PLUMBING
The fresh water fill valve located in the service
compartment near the water hook-up determines whether
the city water is going through the water system or into
the fresh water tank. The excess water will be vented from
an overflow vent pipe onto the ground when the tank
capacity has been reached. This pipe is installed in the
fresh water tank to prevent tank rupture from overfilling.
Fresh water tank drains are located a few inches in front
of or beside the fresh water tank and are connected to
the fresh water tank with a 1/2” or 1” water line.
Whenever possible, drain the fresh water tank before
traveling or only carry what you will need to get to your
destination. Water in the tank will reduce the carrying
capacity of the coach. All of the water should be drained
from the fresh water system when the coach is not in use
for more than one week to prevent stagnant water and
reduce organic growth. To drain the fresh water tank,
open the low point drain valve located near the fresh
water tank.
Fresh Water Tank and Drain
This article provides a basic overview of the fresh water tank and drain. This tank is used to hold fresh potable water for use
throughout the water system and is usually located on the floor of the water compartment; however, some coach floorplans
may be equipped with a water tank located in another compartment. The fresh water tank is filled from the city water hook-
up with a hose or hose reel.

CONFIGURATION EXAMPLES
Fresh Water Valves
The article provides a basic overview for the Fresh Water Valves in a coach. The rotating “Fresh Water Valve” located in the
water compartment is used to pressurize the fresh water system in your coach, as well as to fill the fresh water tank when
the coach is connected to city water.
If you leave this valve in the manual tank fill position,
you may experience low water pressure while
operating the water pump.
IMPORTANT
!
The Fresh Water Valve position determines whether the
water supply fills the tank or pressurizes the fresh water
system in the coach. Simply rotate the “Fresh Water
Valve” to the appropriate position to perform the desired
function.
FRESH WATER VALVE EXAMPLES
Auto Fill
For coaches equipped with an Auto Fill function, the
coach must be connected to a pressurized water source
and have the Fresh Water Valve in the “Auto Fill” position.
In addition to turning the valve, the coach must also have
the Auto Fill function enabled within the tank monitoring
system. This function is used to automatically fill the fresh
water tank and shut o
ff
the water supply based on the
tank levels. The system will turn on the Auto Fill valve
when necessary and turn it o
ff
when the tank reaches
capacity.
Both the Precision Circuit Digi-level and the KIB TMSC-
100 systems control the electric auto fill valve via the
monitor panel in an overhead panel and are fused in the
12 volt house fuse panel. The KIB TMSC-100 system’s
circuit board is typically located in the shore cord
compartment, and the Digi-Level does not use a separate
circuit board.
