-The
external gravity water 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
possible, drain the fresh water tank before trav-
eling. Water in the tank will reduce the carrying
capacity
of
the motor home. See Motor Home
Loadillg section
of
the
011
The
Road
chapter.
The main water tank
"quick-drain" valve may
be located on the end
of
the water tank, or in the
utility compartment.
Water Pump
The on-board fi'esh 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.
It
can run
dry for extended periods without damage.
See
Electrical Systems chapter.
07-2
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. .
1.
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.
Troubleshooting the
Fresh Water
System
Water system problems usually fall into two
categories: Inherent system problems, and prob-
lems caused by neglect.
System problems are
usually the result
of
road vibration and campsite
water pressure variations.
Problems
of
neglect
usually stem from failure to clean filters,
