Pressure Washer with Low Water Output

If you’re experiencing low water output from your pressure washer, it can be quite frustrating. But don’t worry, we’re here to help! In this article, we’ll guide you through some troubleshooting steps to help you identify and fix the issue. By following these steps, you’ll be able to enjoy the full power and efficiency of your pressure washer once again.

Inspect the Water Source

The first thing you should check is the water source. Make sure that the water supply to your pressure washer is fully turned on and that there are no restrictions or blockages in the supply line. Sometimes, low water pressure can simply be caused by a partially closed valve or a kinked hose. Ensure that the water supply is adequate and uninterrupted before proceeding to the next steps.

Check the Inlet Screen

The inlet screen is responsible for filtering out any debris or particles that may be present in the water. Over time, this screen can become clogged, leading to decreased water flow and pressure. To check the inlet screen, you’ll need to locate it where the water hose connects to the pressure washer. Disconnect the hose and remove the screen. If it’s dirty or clogged, gently clean it with water and a soft brush. Once cleaned, reattach the screen and hose, and test the water output.

Examine the Hose

A damaged or kinked hose can also cause low water output. Inspect the hose for any signs of wear, such as cracks, leaks, or bulges. If you notice any damage, it’s essential to replace the hose to ensure optimal water flow. Additionally, make sure that the hose is not twisted or kinked, as this can restrict the water flow. Straighten the hose if necessary and ensure it’s properly connected to both the pressure washer and the water source.

Inspect the Nozzle

The nozzle plays a crucial role in determining the water output and pressure of your pressure washer. Over time, the nozzle can become clogged with dirt, debris, or mineral deposits, leading to reduced water flow. Inspect the nozzle for any blockages and clean it thoroughly using a small wire or pin. If the nozzle is severely damaged or worn out, it’s recommended to replace it with a new one to restore optimal performance.

Clean the Pressure Washer Filters

Pressure washers often have built-in filters to ensure the water used for cleaning is free of impurities. However, these filters can become clogged, especially if the water source has a high mineral content. To clean the pressure washer filters, refer to your user manual for specific instructions. Generally, you’ll need to locate the filters, remove them, and rinse them with clean water. Once the filters are clean and dry, reinsert them into the pressure washer.

Check for Clogs in the Pump

Another common cause of low water output is clogs within the pump. Over time, debris, dirt, or mineral deposits can accumulate within the pump, obstructing the water flow. To check for pump clogs, you’ll need to refer to your pressure washer’s user manual for guidance. Usually, you’ll have to disassemble the pump partially and clean out any blockages. It’s important to be cautious and follow the instructions carefully to avoid causing damage to the pump.

Examine the Unloader Valve

The unloader valve is responsible for regulating the pressure within the pressure washer. If the unloader valve is not functioning correctly, it can cause low water output. Inspect the unloader valve for any signs of damage or wear, such as leaks or cracks. If you notice any issues, it’s recommended to replace the unloader valve to ensure optimal performance.

Inspect the Pressure Relief Valve

The pressure relief valve is designed to release excess pressure from the pressure washer. However, if this valve is faulty or malfunctioning, it can result in low water output. Inspect the pressure relief valve for any damage, leaks, or blockages. If necessary, consult your user manual or contact a professional to replace or repair the pressure relief valve.

Check for Worn or Damaged Components

Lastly, it’s essential to inspect all other components of your pressure washer for any signs of wear or damage. Check the fittings, seals, and connectors for leaks or cracks. Examine the high-pressure hose for any bulges or punctures. If you identify any worn or damaged components, it’s crucial to replace them as soon as possible to ensure optimal performance and prevent further issues.
