Problem: my pressure cleaners ‘pulses’ when I’m not using it
By term pulsing, we mean once you release the trigger on your lance the machines surges and doesn’t idle correctly. However, when you engage the trigger the machine performs as normal. In many cases pulsing is a result of a water leak. Usually there is a leak inside of the pump, trigger or pressure hose. We recommend you inspect these items to attempt and narrow down the problem. If there is no detectable leak, it means your leak is inside of your pump. We recommend you contact your local pressure cleaning repairer.
