Pressure washers: Can your tap cause problems?

If you're a pressure washer owner, you will know that they can provide great cleaning results. They have become essential items for cleaning the garden and outdoor items. However, have you ever wondered if any performance issues could be caused by your garden tap? In this article, we look at how tap issues can affect your pressure washer. 

The importance of your water supply

To understand how tap issues can affect your pressure washer, we need to understand the importance of having a steady water supply. Pressure washers need a continuous flow of water to create the right amount of pressure. If the water supply gets interrupted or fluctuates, it can directly affect how well your pressure washer performs. Depending on the nature of the tap issue, you may need a plumber to assist in rectifying the issue. 

Low water pressure

If your tap is experiencing low water pressure, it can affect your pressure washer’s effectiveness. Insufficient water pressure leads to reduced cleaning power, making it more difficult to remove stubborn dirt and grime effectively. Additionally, low water pressure can cause the pressure washer to continuously cycle on and off, which can strain the motor and reduce its overall lifespan. 

Inadequate water flow

Insufficient water flow, often caused by a partially blocked or corroded tap, can also impact the pressure washer's performance. Without sufficient water flow, the pressure washer can't generate the right pressure to clean effectively. This can make your cleaning tasks take longer and become more frustrating.  

Blocked or partially clogged tap

If you notice a decrease in water pressure or flow, it's possible that your tap is partially blocked or clogged with sediment or mineral deposits. To address this issue, you can try removing and cleaning the tap aerator or contacting a professional plumber for assistance. 

Faulty pressure regulator

Some homes have pressure regulators installed to control water pressure. If your pressure washer is not receiving sufficient water pressure, it's worth checking if your pressure regulator is functioning correctly. A faulty regulator might need replacement or adjustment by a professional. 

Leaking tap

A leaking tap not only wastes water but can also impact your pressure washer's performance. This is because the water may leak out of the tap instead of going through the hose, which can thus affect the water pressure and flow. Fixing the leak promptly can help maintain a steady water supply and ensure your pressure washer functions optimally. Click here to read our blog on 5 ways to stop your outdoor tap from leaking. 

What else can we check to avoid problems?

Firstly, you can check the hose connection to prevent problems from occurring. We recommend inspecting the hose connections between your tap and the pressure washer. Ensure they are securely attached and free from any leaks or blockages. 

You can also use a filter. A water filter can help to prevent debris or mineral deposits from reaching your pressure washer. This can help prolong the life of your pressure washer by reducing the risk of clogs or damage. 

Like with any product, you should also ensure you are carrying out regular maintenance. You can do this by cleaning the nozzles, checking for any leaks, and following the manufacturer's guidelines for care. Regular maintenance ensures the best performance and a longer life for your equipment. 



Your tap is important for the performance of your pressure washer. Any tap problems can significantly impact the cleaning power and efficiency of your pressure washer. By addressing these issues, you can improve the water supply, leading to the best pressure washer performance.
