The on-board water storage tank may also be filled
: through a special filler cap outside the motor home. To
fill the fresh water tank, open the spout, remove vent
. plug, and fill the tank using a potable water hose. Check
, the monitor panel often to determine when the tank
IS
full. If water is flowing from the top vent, your tank is
overfilled. Stop filling. After filling the tank, replace vent
plug and filler cap.
-
Avoid leaving water in the tank when the motor home is
not in use. Turn the water pump OFF before draining the
water tank. Whenever possible, drain the fresh water
tank before traveling. Water in the tank will reduce the
carrying capacity olthe motor home. See "Motor Home
Loading" section of the "ON THE ROAD" chapter.
The Water Pump
The on-board fresh water system is pressurized by a
self-priming, 12-volt DC pump. The pump operates
automatically when the pump power switch is ON and a
faucet is opened. When the faucets are closed, the
pump shuts off. At free flow, the pump draws approxi-
mately 7 to 7-112 amps, and can run dry for extended
periods without damage. A 1 O-amp fuse at the converter
panel protects the pump circuit. See "ELECTRICAL
SYSTEMS" chapter.
Turn the pump master switch ON to pressurize the sys-
tem. When a faucet is opened after the initial filling of the
tank, the water may sputter for a few seconds. This is
normal and is not cause for concern. The water flow will
become steady when all air is bled from the water lines.
Water Filter
Dirt mineral scale, and organic matter are filtered out of
the 'fresh water system by an in-line water filter on the
inlet side of the water pump. If you suspect a clogged
filter, it is easily removed and cleaned.
Inspect the filter after the first 90 days of use; clean if
necessary, and inspect annually thereafter.
Loosen the clamp at the inlet end of the filter.
Pull the water line off the filter.
Unscrew the filter from the water pump.
Turn each end of the filter and pull apart.
Flush out and clean screen.
Reverse procedure to install.
Operate the water pump and check for leaks.
Troubleshooting The Fresh Water System
Water system problems usually fall into two categories:
inherent system problems, and problems caused by
neglect. System problems are usually the result of road
vibration and campsite water pressure variations. Prob-
lems of neglect usually stem from failure to clean filters,
improper winterization, and poor battery maintenance.
Most water system problems can be avoided by consci-
entious maintenance.
Leaks
Vibration, flexing and twisting while traveling can work
pipe fittings loose. Check all plumbing for leaks at least
once a year. If the water pump runs when a faucet is not
open, suspect a leak. Be sure the tank drain valves are
tightly closed. Leaks occur most often around threaded
fittings. If necessary, tighten or clean and tighten the
fittings. Do not overtighten fittings. Connections at gal-
ley and lavy fixtures should not be tightened with a
wrench. They will normally seal with hand-tightening. If
a leak persists at one of the fittings, disconnect it
completely and check for mineral deposits or other
foreign matter at the seating surfaces. Clean the sur-
faces thoroughly and reinstall the fitting.
Connections at the water tank, pump and valves are
made with special clamps. They can be replaced with
standard aircraft type hose clamps.
