Pressure washers are an essential tool for cleaning various surfaces, from cars to decks and patios. However, for a pressure washer to work effectively, it needs to have the right amount of pressure. The pressure is controlled by the pressure washer pump, and sometimes, you may need to adjust it to get the best results. In this article, we will look at how you can adjust the pressure on your pressure washer pump.
Before we dive into the process of adjusting the pressure, it is important to understand the different types of pressure washer pumps. There are two main types of pressure washer pumps: axial cam pumps and triplex pumps. Axial cam pumps are commonly found in residential pressure washers, while triplex pumps are mostly used in commercial pressure washers.
The process of adjusting the pressure on your pressure washer pump will differ depending on the type of pump. We will start by looking at how to adjust the pressure on an axial cam pump.
Adjusting the Pressure on an Axial Cam Pump
Step 1: Turn off the Pressure Washer
Before you start adjusting the pressure on your pressure washer pump, make sure that the pressure washer is turned off and unplugged from the power source. This is important for your safety.
Step 2: Locate the Pressure Regulator
The pressure regulator is usually located on the pump. It is a small knob that you can turn to adjust the pressure.
Step 3: Adjust the Pressure
To adjust the pressure, turn the knob clockwise to increase the pressure or counterclockwise to decrease the pressure. It is important to make small adjustments and test the pressure after each adjustment until you find the right pressure.
Step 4: Test the Pressure
Once you have made the necessary adjustments, turn on the pressure washer and test the pressure. You can do this by spraying water on a surface and observing the pressure. If the pressure is too low or too high, repeat the adjustment process until you get the right pressure.
Adjusting the Pressure on a Triplex Pump
Adjusting the pressure on a triplex pump is a bit more complicated than on an axial cam pump. Here are the steps to follow:
Step 1: Turn off the Pressure Washer
As with an axial cam pump, turn off the pressure washer and unplug it from the power source before you start adjusting the pressure.
Step 2: Locate the Unloader Valve
The unloader valve is a small valve on the pump that regulates the pressure. It is usually located near the pressure gauge.
Step 3: Adjust the Pressure
To adjust the pressure, you will need to use a pressure gauge and a wrench. First, connect the pressure gauge to the pump using a quick-connect fitting. Then, turn on the pressure washer and let it run for a few seconds to build up pressure. Once the pressure has stabilized, use the wrench to turn the adjustment knob on the unloader valve. Turn it clockwise to increase the pressure or counterclockwise to decrease the pressure. Again, make small adjustments and test the pressure after each adjustment until you get the right pressure.
Step 4: Test the Pressure
Once you have made the necessary adjustments, turn off the pressure washer and disconnect the pressure gauge. Turn the pressure washer back on and test the pressure by spraying water on a surface. If the pressure is too low or too high, repeat the adjustment process until you get the right pressure.
In conclusion, adjusting the pressure on your pressure washer pump is an important step in ensuring that you get the best results when cleaning different surfaces. Whether you have an axial cam pump or a triplex pump, the process of adjusting the pressure is relatively easy, as long as you follow the steps outlined in this article. Remember to make small adjustments and test the pressure after each adjustment until you get the right pressure. Happy cleaning!
