Before we understand the reasons for the breakdown of sinks, let's first consider the variety of devices of this type. Different types of sinks are used depending on the needs of the user. The difference is in the way of operation and productivity. This range of high pressure washers needs to be described in more detail:

  • the main purpose of washing cars (cars, trucks), special equipment;
  • further in importance: washing of courtyards, workshops, building facades, using a high-pressure extension hose;
  • the third function (for industrial devices) pumping out liquid from flooded places;
  • using a special brush nozzle, you can clean the sewer using a pipe cleaning kit;
  • by adding special tools, you can organize the foam treatment of various painted surfaces using a jet tube with a nozzle.

There are several types of sinks:

  • household - this is the most acceptable equipment for cleaning dirty surfaces mechanically in any hard-to-reach places. The difference between domestic and industrial washes is only in their compactness and mobility, low weight and size, which allows you to enjoy the result of cleanliness yourself, to save time at home, in the country, in the garage.
  • with water heating - designed for organizing cleaning of hard surfaces by double washing (high pressure, hot water).
  • without heating water. For example: Karcher K2 minisink
  • autonomous - access to the power grid is not necessary, performance is provided by a powerful gasoline engine. For example: autonomous device Karcher HD 9/23 G of the Advanced series

After winter, car enthusiasts often face the problem of building up operating pressure in a car wash. It seems that the car wash is working (the engine is noisy), but the pressure of the jet is not enough for efficient operation. In such cases, most often the reason lies in the malfunction of the bypass valve.

But before repairing, you should rinse and clean the nozzles well. If the removal of contaminants did not help, then this means that the bypass is jammed, and it releases pressure into the return line, as a result of which, even after releasing the trigger of the gun, the pump continues to work forcing the water to circulate in a circle. To check, you can simply change the jet nozzle to a mud cutter, the problem remains, so we can safely proceed to the repair.
