Water Systems
SECTION SEVEN
The water pump is operated by the water pump switch
located on the monitor panel . Do not allow the pump to
run with an empty fresh water supply tank . Operation of
the pump without water may damage the water pump .
To operate the pump:
• Fill the fresh water tank .
• Turn on the water
pump
from
the
monitor panel .
• Open faucet valves to
purge system of air .
• Close each faucet
when it delivers a
steady stream of water .
• It will take several
gallons to fill the water
heater tank .
WATER PUMP TROUBLESHOOTING
Vibration induced by road conditions can cause the
plumbing or pump hardware to loosen . Check the water
pump system for components that are loose . Many
symptoms can be resolved by tightening the hardware .
Check the following items:
Water pump will not start or blows the fuse:
• Check the electrical connections, fuse or breaker,
main switch and ground connection .
• Is voltage present at the pressure switch on the
pump? If voltage is present, the pressure switch
may be faulty . As a test, temporarily bypass the
pressure switch .
• Check the charging system for correct voltage and
good ground .
• Check for an open or grounded circuit or motor .
• Check for a seized or locked diaphragm assembly
(water frozen) .
Water pump will not prime or sputters
(No discharge/motor runs):
• Is the pump inlet strainer clogged with debris?
• Is there water in the tank or has air collected in the
water heater?
• Is the inlet tubing and plumbing sucking in air at
plumbing connections (vacuum leak)?
• Check for proper voltage with the pump operating .
• Check the pump housing for cracks or loose drive
assembly screws .
Water pump will not shut-off or continues to run
when the faucet is closed:
• Check to see if the fresh water/tank fill valve is
completely closed .
• Check the output (pressure) side plumbing for
leaks and inspect for a leaky toilet or valves .
• Look for a loose drive assembly or pump head
screws .
Water pump is noisy or rough in operation:
• Check for plumbing that may have vibrated loose .
• Does the mounting surface multiply noise
(flexible)?
• Check for mounting feet that are loose or
compressed too tight .
• Look for loose pump head to motor screws .
Water pump is rapid cycling:
• Look for restrictive water flow in the faucets or
shower heads .
WARNING
Before leaving the motorhome for an extended
period of time (i .e . overnight or longer), be sure that
the city water and water pump have been turned
off . Damage from neglect will be the responsibility
of the owner, not the manufacturer .
CAUTION:
Do not continue water pump operation when the
fresh water holding tank is empty . Damage to the
water pump may result .
