Is your pressure washer losing power when you squeeze the trigger? Frustrating, right? Before you start stressing, let's break down the common reasons behind this issue and simple solutions. From nozzle clogs to inadequate water supply, we've got you covered. In this guide tailored for beginners, we'll unravel the mystery behind why your pressure washer is losing pressure and equip you with the knowledge to restore its full blasting power. Say goodbye to weak water streams and hello to effective pressure washing!
There are a few reasons your pressure washer might lose pressure when you pull the trigger.
If the machine is old, the seals could be worn out, allowing water to leak past them and into the pump. This would cause a loss in pressure.
Another possibility is that the intakes for the pump are blocked or restricted, preventing water from flowing into it properly. This could also lead to a loss in pressure.
Finally, there could be an issue with the unloader valve regulating water flow through the pump. If this valve is defective, it could cause water to bypass the pump altogether, resulting in a loss in pressure.
Whatever the reason, if your pressure washer is losing pressure, it's best to take it to a qualified technician for repair.
