PLUMBING
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 shutoff 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).
FRESH WATER LINES TO THE KITCHEN
The hot and cold plumbing lines
connecting slideout-installed
components, such as the kitchen
sink and other optional equipment
utilizing the coach water supply,
are typically hard-plumbed within
the slideout.
To ensure flexibility, a braided
hose connects the rigid plumbing
from within the slideout to the rest of the plumbing in
the coach. This hose easily moves with the slideout as it
extends and retracts. The plumbing lines are normally tied
to the flexible drain pipe and extend and retract smoothly
as the slideout travels.
Hot and Cold Low Point Drains
Low point drains are normally located in the water
compartment and are marked “Low Point Drains.” Some
valves are mounted in the water control panel and others
are placed close to the water compartment and marked
with a sticker nearby. Typically the coach has one hot
water low point drain and one cold water low point drain,
which are used to empty the water lines. Open the valves
to relieve water pressure and drain the water lines. Close
the valves for normal operation of the pressurized water
system.
LOW POINT DRAIN CONFIGURATION
EXAMPLES
On coaches equipped with tank rinse low point drain(s),
turning the tank rinse drain valve to the “open” position
will remove pressure and drain the tank rinse line. When
finished using the tank rinse, it is recommended to turn
off the water supply to the tank rinse connection. Open
the valve, and drain off the pressure in the line before
disconnecting the water hose.
