PLUMBING SYSTEM
Depending on your camping trailer model,
there may be two different water systems in
your RV: the fresh water system and the waste
water system. If so equipped, the fresh water
system consists of all or some of the following
components: the fresh water holding tank,
fresh water connections, water pump, outside
shower assembly, water heater, faucets,
shower and water purification system. If so
equipped, the waste water system consists of
all or some of the following components: the
sewage holding tank, drains and toilet.
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:
0 Inspect all faucets, the water purification
system (optional) and sink connections
(including drain baskets or filters).
0 Remove the access panels. If so
equipped, inspect the shower faucet
fittings and shower drain lines.
0 If so equipped, 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
drains 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.
FRESH WATER HOLDING TANK
The fresh water tank can be filled by pressure
filling through the fresh water inlet (called city
water) or by gravity fill. There are plastic
overflow tubes plumbed into the fresh water
holding tank. They allow water to flow out of
the water tank. Occasionally, you may see
water coming from the overflow tubes (located
underneath the RV) when the fresh water
holding tank is filled. This is normal, and is
caused by external circumstances, including
the RV being parked on an incline, or the
motion caused by starting or stopping the RV
during travel.
Do not cap, block or modify the fresh water
tank overflow tubes in any way. Enough water
pressure can build up during the filling process
to damage the plumbing system if the overflow
tubes are obstructed.
FRESH WATER CONNECTIONS
There are two types of direct exterior fresh
water connections in your RV: city water and
gravity fill.

microbiologically unsafe or of unknown
quality.
Never leave the RV unattended while filling
the fresh water system.
