PLUMBING
The Fresh Water System consists of the fresh water holding tank, water pump, valves, connection hoses,
and fresh water plumbing lines. This system is responsible for providing potable water for drinking, cooking,
bathing, and all other activities that require clean water. The capacity of your fresh water tank may vary,
depending on the coach model and year.
Fresh Water System
Fresh Water Lines and Low Point Drains Overview
This article provides a basic overview of Fresh Water Lines and Low Point Drains.
Fresh Water Lines
Fresh water lines are used to distribute potable water
throughout the coach. The hot water lines are typically
red in color or translucent with red lettering. The cold
water lines are typically blue in color or translucent with
blue or black lettering.
HEATED FRESH WATER LINES
Fresh water lines located beneath the slideout floor are
typically heated to prevent freezing (i.e. refrigerator water
supply). The water lines are routed in the heated water
bay and inside the heated living area as much as possible.
Heated fresh water lines are typically used on floorplans
with bath fixtures or a refrigerator containing an ice
maker or water dispenser located in a slideout. Heated
water lines are used to connect the plumbing from
the basement area to the refrigerator where the water
lines are exposed under the slideout. The 12 volt power
to the heated water line is usually fused in the cord
compartment fuse panel in diesel coaches and on the
firewall fuse panel on gas coaches.
Some coaches may be equipped with a Manabloc water
distribution manifold that allows water to be shuto
ff
to
individual water lines. For more information about the
Manabloc, refer to Newgle.
Some coaches may incorporate inline water valves on
some water lines which may include the water spigot to
the generator area or other non-heated compartment
bays, ice maker water lines, and/or inline water filters. The
valve(s) could be located various places depending on the
coach year, model, and floorplan (i.e. under the kitchen
sink, under the dinette booth, in the false pantry floor
bottom, under the couch, or in the basement).
