How does the pressure washer pump work? 

A pressure washer pump, also known as the high-pressure pump, is an indispensable part of any pressure washer. The high-pressure pump provides water under pressure to be forced through the lance and cleaned onto the surface. This means it must move large amounts of water at very high pressures, which require specific applications, including incompressible flow and non-lubricated pumps.

The pump consists of a series of increasing, decreasing, and reversing cylinders. The main cylinder is the largest one on the shaft, with multiple smaller chambers following it. This allows for constant high-pressure output, as the fluid discharged from the first chamber can be used to power those that follow.

After the high-pressure pump, the fluid enters into a control valve. This valve can be adjusted to fit your needs depending on what you are cleaning. Once the water leaves the control valve, it is pressurized through to the lance, which directs it onto surfaces at an adjustable spray pattern.

How to install a pressure washer pump?

Once the pressure wash system has been turned off, you must drain the high-pressure pump and any other parts which hold pressurized liquid. The liquid needs to be drained from all open ends of the system to build up pressure and possibly cause damage or injury if released under such conditions.

While some pressure washers come with their draining valves, there are other ways to drain the system. The easiest way is by removing the cap of the high-pressure pump and letting water flow out while ensuring that you do not touch any open electrical connections. Another option is to remove the hose that connects the lance to the pump and drain the water into a bucket.

How to check pressure washer pump?

When checking or changing out your pressure washer pump, you can take some simple actions to ensure that it is working correctly. The most basic way is by inspecting the hose which connects the high-pressure pump to the lance on its end. If there appear to be any cracks or damage, you should replace the hose immediately.

If there are electrical connections on this hose, ensure that they are dry and clean to ensure a good power connection between the pump and lance.

When inspecting your pressure washer pump intake port, bring up some soapy water with a spray bottle. As you turn on the machine, you will see bubbles coming up from the pump intake port. If no bubbles are present, you may have an air leak on your system and should check the intake valve for damage. If there is some visible damage or debris on the valve, remove it immediately before it causes more extensive problems with the high-pressure pump.

How to drain pressure washer pump?

If you are still having problems getting everything up to pressure after draining your pressure washer pump and checking these points, you may need to contact a professional technician. The high-pressure pump should take large amounts of water at high pressures without any issue or decrease in output. If there is little to no pressure coming from the system, it may be time for a new pump entirely.

Knowing where the water comes from, how it gets to the high-pressure pump, and what you can do to maintain your system, you are already ahead of many other pressure washer owners. Using this knowledge in combination with any material provided by the particular manufacturer of your pressure washing system, you should have no issues maintaining your whole power washing process.

It will help if you start by learning the different parts of the system, what they do and how they work together to form your pressure washer system. You can also learn how to maintain each part of your power wash machine through simple techniques like draining it after use or making minor repairs like replacing clogged nozzles or intake valves.

With this knowledge, you will use your pressure washer with confidence, knowing that it is safe and working correctly. With an air of confidence, you’ll be able to tackle any cleaning project!
