DIY car wash

Do you want to build a car wash with your own hands?

DIY car wash

In order to build a car wash with your own hands, you need to spend a lot of effort, time and money.

This is quite a difficult task, since you will face many difficulties associated, oddly enough, not with the construction of the building itself, but with obtaining permits from a huge number of city services, which can take years.

Don’t be surprised, these are very realistic deadlines, and this is only if everything is in order with you, otherwise you will not receive a building permit.

Do-it-yourself car wash – how to choose the right plot of land?

Next, you will need to select a plot of land for the construction of a car wash that would meet a huge number of different criteria.

Here are a few basic ones: Firstly, the land plot must have a specific purpose, which will indicate that a car wash will be built, and not a restaurant or gym. If the land plot does not have a designated purpose or needs to be replaced, this is much more difficult.

In this case, we recommend that you immediately come to the selected site with a specialist and determine whether it is generally possible to build a car wash in this place? What will be the distance from residential or private houses to a car wash, etc.

Secondly, all necessary communications must pass in close proximity to the site: gas, electricity and water supply to ensure the functioning of the car wash. And precisely in the vicinity, because you will have to pay for each linear meter of communications supply.

Thirdly, the land plot must be located in a busy place with a large flow of cars, so that it has convenient entry and exit. For example, next to a Shopping or Business Center, on busy avenues and streets, next to a large concentration of cars, for example, parking lots, car markets, car parks, etc.

Do-it-yourself car wash – what is the deadline for obtaining permits?

As mentioned earlier, the entire process of obtaining the necessary permits for the construction of a car wash, on average, will take 1.5 years or more. Especially if you are not going to resort to the help of various private companies that help speed up the process, but will do everything yourself.

Then the construction process will begin, where it is necessary to take into account many important factors so that the construction does not drag on indefinitely.

How to avoid many problems at the preparation stage and speed up the construction of a car wash as much as possible, read the article: building a car wash - project development, purchasing a plot, etc.

Waterless car wash – car wash start-up time is 2 weeks, total cost from RUB 99,900

Nowadays, an interesting alternative to conventional water washes has emerged - waterless washes, which do not require connection to water, electricity or sewerage.

The car is completely washed without using water.

Thus, such car washes can operate anywhere in the city, and an even bigger advantage is that there can be an unlimited number of them in different places in the city.

How to wash cars using this method is described in more detail in the technology section.

DIY high pressure car wash

DIY high pressure car washing is our topic today. If a high-pressure car wash is more common for your car, you can do it yourself. The main advantage of high-pressure car washes is the creation of a directed jet of liquid, which effectively washes away dirt from the surface; see here for more details on how to wash a car.

The high-pressure jet appears thanks to a high-performance pump and is formed by a special tip.

Just always remember about environmental friendliness when washing your car! The engineering and construction complex disposes of car wash sludge, removes and disposes of sludge sludge, which is so harmful to the environment. And washing a car with your own hands spoils nature!

This type of car wash can be purchased, but it is better to assemble it yourself.

To do this, you must first buy parts to assemble this device. The most important and expensive part of a car wash is the pump. It must be highly productive. In addition, this pump must develop a pressure of up to 200 bar.

When choosing this part of the system, it is important to pay attention to what materials were used for their production. The best option is if the working part of the pump includes pistons made of durable metal or ceramics and brass cylinder heads. The KShM inserts should provide a large support area.

To save money, car washes are assembled from a compressor, which is a faster option, but in this situation the compressor does the work of the water pump.

Another important part is the electric motor. A home car wash must have an electric motor with a power of 220 watts, or single-phase. This is the safest type of connection, which saves significant money.

Some car washes install condensers and single-stage gearboxes. These elements make the device easier to use and increase its service life, although they are not required.

Do-it-yourself high-pressure car wash - we need a coupling. This element connects the pump and the electric motor. The best option for a high-pressure washer is a “soft” coupling, which compensates for the axial misalignment of the shafts. This type of coupling is a fuse when the gearbox or pump jams.

An important design element is the water container. In order for the pump to operate evenly and smoothly, it needs a certain volume of water. A tank connected to a water supply is used as a container for this.

At the outlet of the tank, a special fine mesh is installed, which is used as a filter. This is necessary to protect the pump from dirt and maintain its operation. The washing effect can be significantly improved by adding detergent to the tank.

A necessary element is a regulator indicating the pump's performance. In many cases, the regulator is sold with an auto-unload valve. This device, if necessary, redirects water back to the container to avoid overloading the pump.

When creating a car wash yourself, use a frame as a base for the parts. In addition, you need to buy high-pressure hoses, as well as a gun with a nozzle. When the elements are installed on the frame and connected, the assembly of the car wash can be considered complete and you can start using this device.

DIY car wash. How to make a car wash: tips, recommendations

Washing your car with a rag and a bucket is, of course, good, but it is a somewhat outdated method.

Have you ever seen a car being cleaned in car washes in this old-fashioned way? If yes, then don't go back there again. They clearly skimp on quality and neglect their employees.

So, in this article we will talk about how to do a car wash with your own hands. The thing is very interesting and useful.

Features of a high pressure car wash

We can say that such equipment is not a luxury. Today this is already a necessity. The fact is that this is the only way to properly wash the engine compartment, underbody and body of the car. But most importantly, this requires virtually no effort. All that is required of you is 20 minutes of attention.

As for the design, there is nothing complicated about it. There is a high-performance pump that creates pressure in a container with liquid. The jet comes out directed through the use of a special tip. Everything is quite simple and effective.

In addition, a self-made car wash can also be used for household needs. Wash the windows in the house, spray the flowers against parasites, etc.

Well, now, in fact, let’s move on to the main part of this article and figure out what is needed in order to assemble such equipment and how to do it.

Main components of a car wash

Although we will assemble the equipment ourselves, that is, in our workshop, we will need purchased parts, which, unfortunately, are often not possible to find in our garage. The first thing we need is a high-performance pump. It should create a pressure of 100 to 200 bar.

Such equipment will be quite productive and will be perfect for achieving our goals. When choosing a pump, you need to pay attention to what material it is made of. For example, the piston group is metal or a ceramic alloy, and the block heads are brass.

Of course, you can go the alternative route and use a compressor instead of a high-pressure pump. It will be cheaper, but the system will be less productive.

Motor selection

We can't do without a good engine. It makes sense to choose a single-phase motor of low power. By the way, you can find it in your garage or remove it from an old washing machine or similar equipment. In general, a power of 200-300 watts is quite sufficient.

A single-phase motor is an order of magnitude safer than a three-phase motor in terms of connection and somewhat more economical, so we will focus on it. But whether your car wash will have a condenser and gearbox is up to you to decide. Such equipment can extend the service life of the system, but will significantly complicate the design.

In addition, these elements are not at all mandatory; everything will work fine without them. In any case, doing a car wash yourself is not that difficult. Let's move on to the practical part.

DIY high pressure car wash

Before proceeding directly to assembly, you need to acquire additional elements. We will need a coupling to connect the pump and the electric motor. It is best to take a so-called soft coupling, which will compensate for a slight deviation of the shafts from alignment.

Another important element is the water container. In this case, a plastic tank is the ideal solution. It is easier to carry than metal, and in terms of durability it is not inferior to the latter.

It needs to be connected to the water supply network so that there is always water in our container. At the outlet of the tank we install a fine mesh that acts as a filter. It will protect the pump from damage by foreign bodies.

Well, now let’s see how to assemble a high-pressure car wash with your own hands.

Assembly of the structure

In general, there is nothing complicated here. By the way, it is advisable to install a performance regulator. This element is optional.

The fact is that it comes complete with an automatic unloading valve, which, if something happens, relieves pressure and takes the load off the pump. A regulator is necessary in order to change the pressure in the system.

Therefore, you can set it to maximum - and the jet will be very powerful - and to minimum - in a weak operating mode.

A metal frame is used as a single base for all assembled parts and assemblies. An electric motor, a pump and a gun with a nozzle are attached to it. All this is connected to each other using high-pressure hoses.

Pay attention to the quality of the connections, as they will be subject to serious stress during operation. After the structure is assembled, the mini-car wash is ready for use. Check it out. If everything is in order, then you can use it.

In case of insufficient pressure, we check the tightness of the connections and the operation of the pump.

Homemade car wash and its features

We have already figured out that it will be much cheaper to buy all the parts and assemble them yourself and get ready-made equipment. But I would like to note that a homemade car wash has a number of features.

Firstly, its repair is significantly simplified. In particular, we are talking about replacing failed components. Secondly, you can use any attachment.

If you need to get a concentrated stream, one type is suitable, if diffused - another.

Many people make mistakes at the stage of connecting the sink to the central water supply. The fact is that the length of the hose should not exceed 7 meters. This will eliminate possible pressure surges. If you neglect this requirement, then nothing good will happen.

In the case when a mini-car wash operates from a tank, you need to carefully select its volume. It is advisable to take a container of at least 30 liters and equip it with a check valve so that during operation it is possible to build up pressure.

If you often wash a heavily soiled car at low temperatures, you will need a homemade car wash foam generator. The price of purchased equipment is about 5-9 thousand rubles. Agree, the amount is not small.

It can be made from a regular plastic sprayer, which is then connected to the sink.

Need to take into account

In general, we have figured out how to make a car wash. As you can see, there is nothing complicated. But there are a few simple rules that will help extend the life of such equipment. It is periodically necessary to check the reliability of connections, including threaded ones. If they are loose, don't forget to tighten them.

Since the tank has a filter element in the form of a mesh, it will gradually become clogged. If you do not clean it, it will eventually reduce the flow of water to the pump. Remember to periodically inspect the filter and change or clean it if necessary. Well, when assembling the structure, use popular drawings of car washes, one of which you can find in this article.

They will help you figure out what's what and carry out the installation correctly.

Conclusion

Doing a car wash yourself is not difficult. You can sit and think much longer: “Shouldn’t I do the sink myself?” If you finally take it and start, the assembly work will be completed in a few hours.

In any case, it makes sense to remember that your car's paintwork does not last forever and needs to be carefully maintained. By the way, many car enthusiasts do not recommend using car washes with a pump that creates a pressure of more than 200 bar.

If such equipment is used at full capacity, there is a possibility of damaging the car’s paintwork. And the load on the engine and working parts of the units increases significantly.

Even if there is a need to create high pressure, use it in short-term modes. In principle, this is all that can be said about how to build a car wash.

Do-it-yourself car washing: how to wash a car at home?

Content:

The appearance of the car worries every owner, so car washing is an important procedure that absolutely all fans of four-wheeled vehicles face. Today there are many services that provide similar services. However, they are not cheap, so most owners carry out this process with their own hands at home.

This procedure is very simple and does not require much time, but still some points should be taken into account if washing is done with your own hands. Not only the appearance of the car, but also the durability of the paintwork depends on this. Improper washing with your own hands can not only ruin the appearance of the car, but also reduce the time until the next body repair.

Separately, it is worth saying a few words about the frequency of washing the car, since some attach great importance to this issue. Basically, the opinions of car enthusiasts here are divided into two sides. One of the parties follows a simple rule: if you get dirty, wash yourself. Others believe that excessively frequent car washing is harmful to the paintwork.

Both sides have reason to think so, but in essence, the whole matter is in the psychology of each individual car enthusiast, and the car can be washed as often as you like. You just need to follow the basic rules that will help preserve the paintwork.

And the opinion is dubious when a dirty car retains its original appearance for a longer time - under the influence of dirt and dust, the varnish gradually deteriorates. Here you can give only one correct advice, which will be difficult to argue with.

Its essence is this: if it is not possible to wash the car in the proper way, that is, there are no equipment or detergents, then it is better to postpone washing until a more convenient opportunity.

The situation is approximately the same with do-it-yourself winter car washing. When caring for your car in the cold season, you should also follow the advice above. Additionally, we can recommend not washing the car with hot water, not using excessively high jet pressure and paying special attention to drying the body.

To properly wash a car with your own hands, you need to prepare:

a source of running water with a normal pH level;
flexible hose and special nozzle with different water spray modes;
container for dissolving car detergent;
the detergent itself – shampoo or gel;
soft clean sponge;
a set of rags for drying glass and paintwork;
polish based on wax and rags for applying it.

If you have the opportunity to purchase household cleaning equipment, the process will be much easier. However, the majority make do with the means that are on the list. You should pay attention to the detergent - in no case should you buy the cheapest one. It is also important to periodically refresh your wash sponge and rags.

Before you start washing your car, you need to position it correctly. Direct exposure of the sun's rays to the surface of the body should be avoided. This leads to the formation of streaks and damage to the paintwork due to the optical refraction of light through water droplets. It is advisable to keep the body itself in a cool place for a while so that it cools down.

Next, you should soak the layer of dust and dried dirt. At this stage, under no circumstances should you use brushes or even a sponge, as grains of dirt and sand will act as an abrasive - no worse than sandpaper.

This will soon lead to fading of the paint and the formation of cobwebs in the form of small and deep scratches.

Washing a car with your own hands begins with simply wetting the entire surface; it is advisable to repeat this procedure several times.

After this, you can treat the body with detergent. In case of severe contamination, direct contact of the sponge with shampoo and the surface should be avoided. It is better to first squeeze out the foam at some distance and give the chemicals time to work.

After this, you can rinse the car again and reapply the foam. Now you can use gentle movements of the sponge over the surface. When washing using special products, you need to ensure that the foam does not have time to dry out.

That is, washed areas must be rinsed in a timely manner with copious amounts of running water.

Throughout the entire process of washing a car with a sponge, it should be washed and moistened in a detergent solution as often as possible, this is especially true for glass.

The car should be washed from top to bottom, conditionally dividing it into individual parts - roof, windows, hood, and so on. The sills and rims are washed last. At the same time, you should avoid cleaning the discs with brushes, as many do.

Their coating is also sensitive to mechanical stress, and they can be damaged very quickly.

After the car is completely cleaned of dirt with detergent, it is rinsed generously with clean running water. In this case, it is necessary to carefully treat all cavities that are intended for drainage of rainwater. Rinsing should be continued until clean, clear water without impurities comes out of the drains.

After this procedure, you can begin drying. You can first collect water from the surface using a soft silicone scraper. If there is none, then the water is collected using a rubberized rag. Thus, the entire surface is brought to a completely dry state without streaks.

To ensure the best washing effect, it is advisable to cover the car with a layer of wax-based polish. This does not need to be done every time - it will be enough to carry out the polishing procedure once every three washes.

To do this, the liquid product is gradually applied to the surface of a separate part of the car (roof, hood, door, etc.), and then rubbed until a deep shine is obtained.

This treatment will help to better preserve the paintwork, increase the intervals between washes and give the car an attractive appearance.

Do-it-yourself high-pressure car wash – access around the clock + video

Do you know that if your car is more accustomed to a high-pressure car wash, you can also provide it with such luxury with your own hands without special stations?

Features of a high pressure car wash

Why are most special stations equipped with this type of washing? This is due, first of all, to the fact that with the help of this device you can wash the body, underbody, suspension, engine and engine compartment without making much effort.

The main positive feature of a high-pressure car wash is that a directed jet of liquid easily and effectively washes away dirt from the surface of an object.

This jet occurs as a result of the operation of a high-performance pump, and is formed by a special tip.

Such a device will be useful not only for washing cars, but also for various household needs. So the intention to acquire your own system will solve many everyday problems, especially if you have a plot of land with a spacious house at your disposal.

At least cleaning street communications and paths will happen many times faster. There are many stores that sell this type of product, but it is much more pleasant to make a high-pressure car wash with your own hands.

Moreover, this process is not particularly complicated.

Do-it-yourself high-pressure car wash - basic elements

The first thing you need to do is purchase all the parts that you will need to assemble the device. The most important and expensive part of a car wash is the pump. It must be highly productive. In addition, such a pump must develop a pressure of up to 100-200 bar.

When choosing this part of the system, it is very important to pay attention to what materials it is made of.

The most optimal version of the working part of the pump should look like this: the pistons are made of durable metals or durable ceramics, the block heads are cast from brass, and the liners of the crank mechanism need to be provided with a large support area.

Another important part is the electric motor. For a home car wash, it is best to use a 220-watt electric motor, that is, single-phase.

This type of connection is safe and significantly saves money. Some car wash designs require the presence of condensers and a single-stage gearbox.

These items may make the device easier to use and also increase its service life, but they are not required.

Collecting additional elements for a car wash

When creating a car wash with your own hands, you will also need a coupling. This element connects the pump and the electric motor. For a high-pressure washer, the best option would be to use a “soft” coupling, since it can compensate for the misalignment of the shafts along the axis. In addition, this type of coupling plays the role of a fuse in case the pump or gearbox jams.

An important element in the design is the water container. After all, in order for the pump to operate smoothly and uninterruptedly, it must receive a certain volume of water.

Most often, a tank is used as a container, which is connected to the water supply network. At the outlet, a special fine mesh is installed in the tank, which acts as a filter. This is necessary to prevent dirt from getting into the pump and disrupting its operation.

The washing effect can be significantly improved by adding detergent to the tank.

A necessary element is also a pump performance regulator. In most cases, the regulator comes complete with an automatic unloading valve. This device is needed to, if necessary, redirect water back to the container to avoid overloading the pump.

Also, in the process of creating a car wash with your own hands, a frame is used as the basis for all the parts. In addition to this, high-pressure hoses are required for operation, as well as a gun with a nozzle.

After all the elements are secured to the frame and connected to each other, the work on the car wash can be considered completed and you can begin to use this device.

Do-it-yourself car washing

Every car owner knows that a car needs to be looked after. And not only maintain its working technical condition, but also a neat appearance.

The easiest way is to go to a car wash and leave your car in the hands of professionals for cleaning. But not all car owners prefer this method. For certain reasons and circumstances, some people want to wash their car with their own hands.

How to properly carry out a water procedure without damaging the car?

Mini-wash makes work easier

Having a high pressure washer simplifies the job of cleaning your car from dirt. If you want to save time, you can simply rinse the car. To do this, use a mini-wash water jet to spray the car.

Start with the roof, go down the body, and at the end, spray the arches and wheels with water. Moreover, the flow of water must be directed towards the car at an angle of 45 degrees. After the procedure, the car can be wiped down, but it is not necessary.

Here everything depends on desire and weather conditions.

Full car wash

If thorough washing is required, the process becomes significantly more complicated. To begin with, the car body, wheels, arches and bottom must be completely doused with water to remove most of the dirt. To carry out quality work, you must first eliminate point contamination. This is done by applying special auto chemicals for various purposes:

for rubber;
for disks;
for plastic parts;
for removing insect marks and other stains.

After applying the necessary chemicals to the car, it is recommended to wait a couple of minutes so that the products are absorbed and the expected effect is obtained. Then we pour car shampoo into the foam generator and put it on the high-pressure apparatus.

The nozzle simultaneously supplies car chemicals and water, turning them into foam, which we cover the entire car with. According to the technology, it is applied with a ladder from the bottom up and remains on the car until it begins to drain.

You will have to wait about two minutes, then we begin to wash off the foam in the same way as we applied it - from the bottom up, using a ladder.

The culminating stage of cleaning a car with your own hands is to thoroughly rinse it and wipe it dry. You need to start this procedure from the roof of the car and go down. Upon completion of washing, the body can be treated with protective wax. And renew the visible part of the tires with a special ink.

What auto chemicals are suitable for a mini-wash?

There are many car shampoos on the shelves today. But if you plan to wash your car using additional equipment, then you should choose a special product for high-pressure washers.

This chemistry forms a good foam and is endowed with properties for the highest quality cleaning of a car from various contaminants.

And to ensure maximum shine for a clean car, it is better to choose a wax with an intense water-repellent effect.

Do-it-yourself car wash without additional equipment

To wash your car with your own hands, you need to stock up on a rag, a sponge and a bucket. There should also be a source of water within walking distance. If there is a water supply nearby, then a watering hose will come in handy, which will replace a bucket. We begin washing with our own hands with water douches. We completely soak the car, starting from the top. Don't forget about the wheels and the bottom.

After preparation, dilute car shampoo in a bucket of water and apply foam to the car. You must use a DIY cleaning product. After a short wait, the shampoo must be completely rinsed off the surface of the body and the car wiped with a prepared damp cloth. If desired, the paintwork can be waxed and the tires treated with ink.

When carrying out the procedure yourself, you must use a special car shampoo for hand washing as the main cleaning agent.

As for the rest of the auto chemicals - waxes, polishes, means for removing local contaminants, ink - when choosing them, it does not matter how you want to wash the car.

The same products are suitable for both DIY washing and using a high-pressure apparatus.

Where can you wash your car yourself?

The methods for washing a car with your own hands are quite simple and straightforward. But difficulties may arise with the location of the procedure. The point is that you can’t wash your car just anywhere.

There are legal restrictions on the territory of the Russian Federation, for violation of which real fines are issued.

Moreover, similar laws exist in Kazakhstan, and in Belarus, and in a number of other countries.

Federal law prohibits washing a car in environmentally protected areas and near any bodies of water. It is legally stipulated that you can wash your car yourself only in places specially equipped for this. This should be a concreted (asphalted) site with the possibility of running water and a sewer system with filter cleaners.

It turns out that it is illegal to carry out procedures simply on the street. But there are not so many places that meet these requirements. You can use the self-service service that is offered at some professional car washes. All conditions have been created there, the necessary equipment is available. But there are time limits, which is not always convenient.

An alternative could be areas in a closed garage complex, allocated for these purposes and equipped accordingly. It will be convenient to wash your car here. But the site is not accessible to everyone. The lucky ones are the owners of a private house or cottage. It is not prohibited by law to wash a car on your own territory.

Dangers of washing your car yourself

If you decide to wash the car yourself, to avoid unwanted consequences, you should consider some points:

When washing by hand, do not rub the body too hard with a sponge; you can scratch the paintwork with fine abrasives that are part of the dirt.
If you have recently painted your car, you should not use a mini-wash; the paint will come off under strong water pressure.
In winter, you need to wash your car only with cold water, otherwise the glass, mirrors, headlights, and paint on the car may crack due to sudden temperature changes.
You can start washing your car in the cold season only when you have managed to wash off the ice crust from all treated surfaces of the car, otherwise the procedure will be useless.

Happy water treatments!

How to make a mini high pressure washer?

A DIY pressure washer can be created using inexpensive parts. Such units have become widespread.

Using the device, you can wash the terrace of your house or cottage, wash your car, and do many other operations that require the presence of high-pressure water. Anyone who has basic tool skills can do a wash.

In appearance, the homemade unit looks like a small portable suitcase or a floor polisher. Its body is made of silumin or plastic.

Diagram of a high pressure washer.

How does this type of washing work?

An electric motor is installed inside the unit, the shaft of which is connected to a plunger swash plate. When moving, the plunger describes a reciprocating trajectory.

At the upper and lower sections of this curve, the valves open alternately: suction and high pressure. Through these devices, water enters the hose and then into the sprayer.

What are the technical characteristics of such a sink?

Assembly diagram with open and closed bypass.

To determine the required power of such a device, you need to know how often you plan to use it.

With a high frequency of work with such a washer, its power should be increased - the performance of the device increases along with the increase in the pressure of the water jet.

The efficiency of the entire device depends 75-85% on fluid flow. The required amount must be supplied to the unit, otherwise the sink may fail.

The temperature of the water used must be within the operating range applied in the pump design. Typically this indicator varies within 55 degrees. Creating such a sink does not take much time and saves money. The advantages of creating such a homemade unit are as follows:

The device does not contain highly complex components.
It's easy to use.
The efficiency of such a unit is on par with samples purchased on the construction market.
Low probability of damage to any treated surface.
Possibility to carry out independent repairs of the device if necessary.

Scheme of a homemade mini-wash.

You can make a sink from such parts as:

High pressure pump.
Electrical engine.
A special coupling that connects the first two positions.
Tank for water and detergents.
Main frame.
A gun equipped with a nozzle.
High pressure hoses.
Various attachments.

Such a unit works on the following principle: after the unit is connected to the water supply network, the water goes into a container where it is pumped through a pump. Then it is fed to hoses and through them is directed to a gun with a nozzle, through which any surface, for example, a car hood, is cleaned.

What parts are needed to assemble such a device?

First you need to buy a pump. This is the main detail of homemade units of this type. It should have fairly high performance at a pressure of 0.1-0.2 kilobar.

Particular attention should be paid to the material from which it is made. You need to choose a model in which the head on the cylinder block is made of brass, and the pistons of the pump itself are made of high-strength steel or ceramics.

The duration of operation of the created sink depends on this.

Washing power diagram.

The other main part of the unit is the electric motor. As its speed increases, the performance of the washing pump also increases. For such devices, electric motors with a power of 2-3 kW at a shaft speed of 1.5-2 thousand revolutions per minute are best suited. To ensure reliable engine starting, it can be equipped with starting capacitors.

The coupling must be soft: if the pump or electric motor jams, it will act as a fuse.

The water tank can be selected from 5 to 22 liters. It is advisable to install a filter at the outlet of this vessel. Usually this role is performed by a fine mesh. It traps unwanted particles in the water and prevents them from entering the pump.

The frame is the base on which all the elements of the sink are attached. Most often it is made from curved pipes. You can attach a stop and wheels to it, which will make it possible to move the sink. The frame has handles for carrying it around the work site.

For hoses, plastic and rubber hoses with reinforcement inside are best suited. Their thickness is selected to the average diameter. All their connections in the unit must be sealed and made of material that is not afraid of corrosion.

A pistol with a nozzle must be selected so that its trigger operates smoothly, without jerking. Tips are bought ready-made . The sink can be equipped with several nozzles that will create the desired jet shape.

How to properly operate a homemade sink?

Handmade homemade car wash.

In order for the unit to operate for a long time without breakdowns, the following recommendations must be followed:

Before work, you should always check all connections and fastenings for reliability.
If there is a filter device at the outlet of the water tank, then it must be cleaned of particles and dirt every day after work.
There is no need to frequently use the washer in maximum power mode, as this sharply increases the load on the pump and can cause its failure.
To protect the washer from power surges, you can equip it with a battery.
When the device is in working position, the gun must always be in the operator’s hand.
It is better not to allow children near the sink: this can lead to an accident.
Water jets should not be directed at people or animals.
This device must not be used in temperatures below zero degrees Celsius.

If repairs are needed, you can do it yourself. But this is only if the design of the sink is known. Most often, the seal wears out in the pump itself. This can lead to a sharp drop in its performance. In this case, it is necessary to disassemble the pumping device and replace all gaskets.

Some designs of such devices have a pressure regulator. When its seals (rubber rings) wear out, the water pressure decreases and the density of the liquid stream decreases.

Technological process of device assembly

Tools needed for work: tape measure, electric drill, hacksaw, wrenches, bolts, nuts, washers.

The main point when creating a structure is the grounding device. To make it, you need to use a flexible cable with three cores. It must be double insulated. Then it must be connected to a plug with a grounding terminal. After this, you can connect the device to the main ground loop.

Then they proceed to installing the sink on the frame. The sequence of operations is as follows:

Install an electric motor with a starting device. This is done using bolts inserted into the corresponding holes on the frame.
Install the electrical cable.
Place the pump and mount the coupling on the motor shaft.
The gun with the nozzle is attached to one of the high-pressure hoses, which extends from the pump outlet.
Attach a water tank to the frame. It is necessary to ensure that all connections are tight.
Complete the installation by installing all high-pressure hoses.

Now comes the stage of checking the operation of the device. To do this, the sink must be connected to the main water supply using a hose, which should be 7-8 meters long. Open the tap and draw water into the tank. After this, the electric motor is turned on. The pump should pump water through the hoses to the gun.

They pull the trigger and see whether the density of the emerging stream of liquid is satisfactory or not. If everything is in order, then using nozzles you can get different types of jets for cleaning different surfaces.

If the water does not come out in the volume that was expected, then you need to check all the fasteners and seals and then repeat the check again.
