    I have an excell power washer

    I recently broke the hose and had to buy a replacement. The power washer ran great up until the replacement. I bought the proper hose (1x4 x 25") made by briggs and stratton. When I tried it out, the power washer would squirt water through the line but I have no pressure.

    Any idea's on what might be causing this?

    When a pressure washer loses pressure, it is usually because the orifice in the outlet end of the tip is restricted. When the orifice is restricted the pressure inside the pump gets very high. The internal relief valve inside the pump opens and the pump circulates water inside to releave the pressure.

    Try different tips to verify this. Run a small wire through the orifice to clean it and remove the tip and run water through the pump for several minutes to clean out the pump and hose.

    The previous hose has 2600 PSI Max, 179 Bar. The replacement is 3,000psi and 207 Bar. I do not know what the BAR means, could this discrepancy be the cause of my issue?

    Bar is a pressure measurment. European. 1 Bar is 14.7 psi. Is the hose the same diameter?
