9 Reasons Your Pressure Washer Might Be Losing Pressure

Power Washer Loses Pressure Intermittent

If you’ve ever used a power washer to clean your home, driveway, or vehicle and noticed that the pressure is suddenly dropping periodically, then it might be due to an intermittent loss of pressure. This can happen for a variety of reasons and understanding what they are is key in being able to properly fix the issue. In this blog post we will discuss some common causes of an intermittent power washer losing pressure as well as how to troubleshoot them.

The first thing you should check if your power washer loses pressure intermittently is the hose connection. If either end of the hose isn’t connected securely then there won’t be enough water flowing through it which can cause sudden drops in pressure. Make sure both ends are tightly secured with no air pockets so all the water runs freely from one side to another without any blockages or leaks.

Another possible culprit could be clogged filters on either end of the hose, these filters trap debris like dirt particles or leaves which reduce water flow and cause a drop in pressure when cleaning surfaces such as cars or driveways that have been sitting for some time before washing them off with a power washer. To solve this issue simply remove any accumulated debris from inside each filter by blowing compressed air into them until all obstructions have been cleared out completely.
