SECTION 8
PLUMBING SYSTEM
There are two different water systems in your
RV: the fresh water system and the waste
water system. The fresh water system
consists of the fresh water holding tank, fresh
water connections, water pump, outside
shower assembly (if so equipped), water
heater, faucets, tub/shower, and water
purification system (if so equipped). The
waste water system consists of the waste
water holding tank, sewage holding tank,
drains and toilet.
PLUMBING SYSTEM MAINTENANCE
Recreation vehicles shake and vibrate while
going down the road. It is possible for
plumbing fittings to come loose. Check all
fittings, pressure and waste, for leaks before
each trip or before vehicle storage as part of
your normal maintenance:
□ Inspect all faucets, the water purification
system (optional) and sink connections
(including drain baskets or filters).
□ Remove the access panels. Inspect the
shower faucet fittings and shower drain
lines.
□ Inspect connections at the water pump
and water heater.
□ At the end of every trip, you should drain
any unused water from the fresh water
system.
There are labels affixed to the exterior of the
RV’s sidewall that indicate the locations of the
water system drains and fills. Be aware some
drain valves may be located inside the RV
(once the exterior label is found, go inside to
find the drain corresponding location).
THE FRESH WATER SYSTEM
All water contains contaminant and mineral
particles that can cause fresh water system
odors. Untreated well water is a major source
of water system odors. The fresh water (or
potable water) system needs periodic
sanitization and winterization to take care of
all the components within the plumbing
system and help discourage the growth of
bacteria and other organisms that can
contaminate the water supply.
Never travel with full fresh, black or grey
water holding tanks.
MONITOR PANEL
The monitor panel located in the Command
Center allows you to monitor the fresh water,
grey water, black water and house batteries
levels. These functions are controlled using
the “tact” switches located on the Command
Center faceplate. The monitor panel operates
on 12-volt DC power supplied by either the
converter or house batteries. Sensors
installed in the holding tanks connect to a
resistor assembly (relaying an electronic
message to the display board). No power is
drawn from the house batteries unless a
switch is pushed or turned ON. Fuses for the
monitor panel are located in the fuse panel.
Operation
Press only one “tact” switch at a time. As you
push either the “FRESH”, “BLACK”, “GREY1”
or “GREY2 (optional)” switch, one or more
LED lights will illuminate indicating that
holding tank content level. When pushing the
“BATT” switch, the highest LED light
illuminated indicates the estimated house
batteries condition.
C = charge at 12.7 volts or above
G = good at 12.1 volts or above
F = fair at 11.6 volts or above
L = low at 6.0 volts or above
FRESH WATER HOLDING TANK
DO NOT drink water deemed
microbiologically unsafe or of unknown
quality.
The fresh water tank can be gravity filled or
pressure filled using the fresh water inlet
(called city water). Plastic overflow tubes are
plumbed into the fresh water holding tank to
allow water to flow out of the water tank.
Occasionally, you may see water coming from
