Pump Check Valves
Storing pump in water, inadequate flushing, or ingested
debris can cause either of the pump’s two check
valves to malfunction. If the pump does not prime
after 30 seconds, try to jar the check balls loose by
tapping the inlet valve with a small wrench as the
sprayer is on and running.
CAUTION:
Excessive shock will fracture or cause
other damage to the pump.

HINT:
To determine if the inlet valve ball is sticking,
unscrew inlet valve from pump and check it. Inlet valve
can be removed without removing suction tube.
If sprayer continues to cycle (motor and pump run)
after you release gun trigger, the pump valves may be
obstructed or worn. If they are worn, Valve Repair Kits
are available. Consult an ASM authorized service
center.
