low spray pressure
-Water turned off.
-Nozzle is not installed, is plugged, or sized
incorrectly
-Inlet chemical injection valve is open without the end
of the pickup tube inserted into detergent.
-Priming of pump after run dry.
-Dual wand valve is open.
-Leaky discharge hose or quick coupler. Water
sprays out around nozzle.
-Inlet strainer clogged.
-Belt slippage.
-Unloader valve worn or improperly adjusted.
-Air leak in inlet plumbing.
-EZ start valve is leaking.
-Turn water on.
-Install nozzle, clean or replace with proper size
-Close soap valve or submerge detergent pickup tube into solu-

-Check valve seat on unloader.
-Reseal fittings and inspect inlet hoses for air leaks.
Pump runs but there
is erratic, fluctuating
pressure
-Inadequate incoming water supply.
-Stuck inlet or discharge valves.
-Restricted inlet or air entering the inlet plumbing on
pump.
-Leaking High Pressure seals
-Leaking Low Pressure seals
-Remove hose to check for internal leaks. Increase water supply
flow.
-Clean out or replace worn valves.
-Check fittings and hose for airtight seal, clean inlet strainer
screen.
-Replace seals.
-Pressure feed the pump & replace seals if water leaks from
pump head.
