Not enough pressure through the hose - Pressure Washers


Answers :

This issue usually comes from a clog in the output of the pump. Isolate the clog by checking one item at a time.

\015\012With the engine OFF, disconnect the output hose from the pump. Turn the output fitting to an open and clear area and startup the engine. If pressure and volume are good then you have a clog in the hose or the gun. Reconnect the hose but unscrew the gun. Test again. If tests OK the gun or the tip is clogged. Reconnect gun and disconnect tip...etc.

\015\012Going back to the first test, if pressure and volume are NOT good at the pump outlet fitting, you have a stuck unloader valve in the pump. Add a few ounces of penetrating oil to the SUPPLY hose fitting and restart the engine. Allow the oil to flow thru the entire unit. Repeat several times if needed. For preventive measures, always add some LIGHT oil to the supply hose and startup the unit after each use. This will keep calcium buildup to a minimum.
