Plumbing Systems and Holding Yanks
CAUTION
Overfilling the fresh water tank from a pressurized
source may cause damage to the water system.
Monitor water tank filling continually.
2. Gravity fill -The external gravity water fill
is located on the exterior of the motor
home. The on-board water tank can be
filled here. To fill the fresh water tank,
remove the cap, remove the vent plug, and
fill the tank using a potable water hose.
Fresh Water Tank Fill
Draining the Fresh Water Tank
Avoid leaving the water in the tank when the
motor home is not in use. Turn the water pump
OFF before draining the water tank. Whenever
pos'sible, drain the fresh water tank before tl'aV-
eling. Water in the tank will reduce the carrying
capacity of the motor home. See Motor Home
Loading section of the On The Road chapter.
The main water tank "quick-drain" valve is
located on the end of the water tank.

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. A fuse at
the converter panel protects the pump circuit. It
can run dry for extended periods without dam-
age. See Electrical Systems chapter.
Turn the pump master switch ON to pressurize
the system. 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 Pump Filter
Dirt, mineral scale, and organic matter are fil-
tered 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 running the first full tank
of water. Clean and inspect monthly thereafter.
The filter is located in the utility compartment
behind the service panel.
I. Loosen the clamp at the inlet end of the filter.
2. Pull the water line off the filter.
3. Unscrew the filter from the water pump.
4. Turn each end of the filter and pull apart.
5. Flush out and clean screen.
6. Reverse procedure to install.
7. Operate the water pump and check for
leaks.
Low Point Drains
To drain hot and cold lines:
1. Open hot and cold low point drains.
2. Open the shower handle and faucet until all
water has drained from the lines.
