To start pump after unhooking city water supply or first time use
proceed as follows:
• Fill the fresh water tank.
• Open all valves and faucets except the drain valves. This includes hot and
cold water valves, all faucets and shower.
• Turn the water pump on and wait for the water lines and the hot water
tank to fill.
• Close each faucet when it delivers a steady stream of water
(cold water faucets first).
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 simply tightening the hardware. Check
the following items along with other particulars of your
system.
The water pump will not start/blows the circuit:
• Check the electrical connections, fuse or breaker,
main switch and ground connection.
• Is the motor hot? The thermal breaker may have
triggered. It will reset when cool.
• Is the voltage present at the switch? Bypass
the pressure switch.
• Does the pump operate?
• Check the charging system for correct voltage
and good ground.
• Look 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 connections
(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.
