Pressure washers are powerful tools that can make cleaning a breeze, but sometimes you need to reduce the amount of water they use. Whether you’re looking to conserve water or simply need to lower the gallons per minute (GPM) flow rate for a specific task, there are several methods you can try. By adjusting the pressure, swapping out the nozzle, or adding an attachment, you can effectively reduce the GPM on your pressure washer.

One of the first steps you can take to reduce the GPM on your pressure washer is by adjusting the pressure settings. Most pressure washers have a pressure control dial or knob that allows you to change the intensity of the water stream. By turning this down, you can decrease the GPM without sacrificing cleaning power. Keep in mind that reducing the pressure too much may result in a weaker stream, so it’s important to find the right balance for your specific needs.

Another method to reduce GPM on a pressure washer is by swapping out the nozzle. Pressure washer nozzles come in different sizes and configurations, each with its own GPM rating. By using a nozzle with a smaller orifice size, you can effectively reduce the GPM without affecting the pressure. It’s worth experimenting with different nozzles to find the one that provides the right balance of pressure and flow rate for your cleaning tasks.

If you find that adjusting the pressure settings or changing the nozzle isn’t enough to meet your GPM requirements, you can consider using a pressure washer attachment. Attachments such as foam cannons, surface cleaners, or water brooms can help distribute water more efficiently, resulting in a lower GPM. These attachments are designed to provide a wide coverage area, allowing you to clean larger surfaces with less water. Just make sure to follow the manufacturer’s instructions when using any attachments to ensure safe and effective operation.

In conclusion, reducing the GPM on your pressure washer can be achieved through various methods such as adjusting the pressure settings, swapping out the nozzle, or using a pressure washer attachment. By finding the right balance between pressure and flow rate, you can effectively conserve water and tailor the performance of your pressure washer to meet your specific cleaning needs.

Adjusting Nozzle Size

Another way to reduce GPM on a pressure washer is by adjusting the nozzle size. The nozzle size determines the diameter of the water stream, which in turn affects the flow rate.

Typically, pressure washers come with a range of nozzle sizes, indicated by a color code. The smaller the nozzle size, the higher the pressure and the lower the flow rate. Therefore, by using a smaller nozzle, you can reduce the GPM output.

To adjust the nozzle size on a pressure washer:

  1. Identify the nozzle size you currently have. This is usually indicated by the color on the nozzle.
  2. Refer to the pressure washer’s user manual or the manufacturer’s guidelines to determine the GPM output for each nozzle size.
  3. Select a smaller nozzle size that corresponds to your desired GPM reduction.
  4. Remove the current nozzle by twisting it counterclockwise.
  5. Insert the smaller nozzle by twisting it clockwise until it is securely in place.

It’s important to note that using a smaller nozzle will increase the pressure, so it’s crucial to adhere to safety precautions. Always wear protective equipment such as safety glasses and gloves when operating a pressure washer, especially when adjusting the nozzle size.

Additionally, keep in mind that adjusting the nozzle size may affect the performance of the pressure washer. While reducing the GPM may be necessary in certain situations, make sure that the pressure washer can still effectively clean the surface you are working on.

By adjusting the nozzle size, you can find the right balance between pressure and flow rate to meet your specific needs while reducing the GPM output of your pressure washer.

Using a Pressure Regulator

When it comes to reducing the GPM on your pressure washer, one effective method is to use a pressure regulator. A pressure regulator is a device that controls the pressure of water flowing through the system, allowing you to adjust the GPM to your desired level.

To use a pressure regulator, follow these steps:

1. Purchase a Pressure Regulator

First, you need to purchase a pressure regulator that is compatible with your pressure washer. Look for a regulator that is specifically designed for pressure washers and can handle the water flow required by your machine. You can find pressure regulators at hardware stores or online.

2. Install the Pressure Regulator

Once you have the pressure regulator, you need to install it in your pressure washer system. Start by turning off the pressure washer and disconnecting it from the power source. Locate the water inlet connection on your pressure washer and remove the existing hose or fitting. Connect the pressure regulator to the water inlet connection and tighten it securely.

3. Adjust the Pressure

After the pressure regulator is installed, you can start adjusting the pressure to reduce the GPM. Most pressure regulators have a knob or screw that allows you to adjust the pressure. Turn the knob or screw clockwise to increase the pressure and counterclockwise to decrease it. Gradually adjust the pressure until you reach your desired GPM.

Note: Keep in mind that reducing the GPM too much may affect the cleaning power of your pressure washer. It’s important to find the right balance between water flow and pressure for your specific cleaning needs.

By using a pressure regulator, you can have better control over the GPM on your pressure washer. This allows you to adjust the water flow to match the task at hand and conserve water when necessary. Follow the steps above to effectively reduce the GPM and optimize your pressure washer’s performance.

Cleaning the Water Inlet Filter

One of the most common causes of reduced GPM (gallons per minute) on a pressure washer is a clogged water inlet filter. Over time, debris and sediment can accumulate in the filter, restricting the flow of water into the pressure washer.

To clean the water inlet filter, follow these steps:

  1. Turn off the pressure washer and disconnect it from the power source.
  2. Locate the water inlet filter, which is usually found at the end of the hose where it connects to the pressure washer.
  3. Using a pair of pliers, unscrew the filter from the hose connection.
  4. Rinse the filter under running water to remove any debris and sediment. If necessary, use a brush to scrub away stubborn dirt.
  5. Inspect the filter for any signs of damage or wear. If the filter is damaged, it should be replaced.
  6. Once the filter is clean and in good condition, screw it back onto the hose connection.
  7. Reconnect the pressure washer to the power source and turn it on to test the water flow. If the GPM has improved, then the cleaning process was successful.

Regularly cleaning the water inlet filter is essential to maintain optimal water flow and prevent damage to the pressure washer. It is recommended to clean the filter after every few uses or as needed, depending on the water source and the level of debris present.

Checking for Leaks

Reducing the GPM (gallons per minute) on a pressure washer can help conserve water and optimize performance. One common cause of high GPM is leaks in the system. To reduce the GPM, it is important to identify and fix any leaks in the pressure washer. Here are some steps to help you check for leaks:

Step 1:

Turn off the pressure washer and disconnect it from the power source.

Step 2:

Inspect the hose connections for any signs of leakage. Look for wet spots or water dripping from the connections.

Step 3:

Tighten any loose connections using a wrench or pliers. Ensure that all connections are secure and free from leaks.

Step 4:

Check the hose for any damage or holes. If you find any, replace the hose to prevent leaks.

Step 5:

Inspect the trigger gun and wand for any cracks or damage. Replace any faulty parts to ensure a proper seal and prevent leaks.

Step 6:

Examine the pump for any signs of leakage. This may require disassembling the pump for a thorough inspection. If you find any leaks, replace the seals or O-rings as necessary.

Step 7:

Once you have checked and fixed all potential leaks, reconnect the pressure washer to the power source and test it. Monitor the system for any new leaks and address them promptly.
