Vibration induced by road conditions can cause the plumbing or pump
hardware to loosen. Check for system components that are loose. Many
symptoms can be resolved by tightening the hardware. Check the following
items:
The water pump will not start/blows the fuse:
• Check the electrical connections, fuse or breaker, main switch
and ground connection.
• Check the electrical connections at the latching controller.
• Is voltage present at the pressure switch? Bypass the pressure
switch.
• Is the latching controller grounding the water pump?
• Check the charging system for correct voltage and good
ground.
• Check for an open or grounded circuit or motor.
• Check for seized or locked diaphragm assembly (water frozen).
The water pump will not prime/sputters: (No discharge/motor runs):
• Is the strainer clogged with debris?
• Is there water in the tank, or has air collected in the hot water
heater?
• Is the inlet tubing/plumbing sucking in air at plumbing connec-
tions (vacuum leak)?
• Check for proper voltage with the pump operating.
• Look for debris in the pump inlet/outlet valves or dry/swollen
valves.
• Check the pump housing for cracks or loose drive assembly
screws.
The water pump will not shut-off/runs when the faucet is closed:
• Check to see if the fresh water tank fill valve is completely
closed.
• Check output side (pressure) plumbing for leaks and inspect
for a leaky toilet or valves.
• Look for loose drive assembly or pump head screws.
• Are the valves or the internal check valve held open by debris
or is the rubber swollen?
