Why is my unit not reaching high pressure?

Cause Solution
Diameter of garden hose is too small. Replace with a 1" (25 mm) or 5/8" (16 mm) garden hose.
Water supply is restricted. Check garden hose for kinks, leaks, and blockage.
Not enough inlet water supply. Open water source fully.
Spray nozzle is not powerful enough. Select a higher pressure nozzle.
Pump is sucking air. Check that hoses and fittings are airtight. Turn "OFF" machine, and purge pump by squeezing trigger gun until a steady flow of water emerges through the nozzle.
