Troubleshooting
Problem Probable Cause Possible Solution
Liquid chemical or air leaks from
the tank into the pump cylinder.
The check valve on the bottom of
the pump cylinder is unable to seal
properly due to dirt, residue, or
damage.
Remove the pump assembly and
examine the check valve. Clean if
dirty; replace if necessary.
The hose leaks air at the tank
connection.
The hose barb adapter is not
inserted into the tank correctly, the

damaged.
Re-insert the hose barb adapter
correctly, tighten the hose nut, or
replace the O-ring.

Disassemble the shut-off. Inspect
all components. Clean and lubricate
parts as needed. Otherwise, replace
the shut-off.

the tank.

Clean the pump gasket and adjacent
sealing surfaces on the pump
cylinder and tank.
Replace the gasket if damaged.
The nozzle tip leaks. The nozzle seal is missing or
incorrectly assembled.
Re-assemble the nozzle and seal to
