PLUMBING AND BATH FEATURES CONTINUED
GRAY WATER HOLDING TANK (P-TRAPS)
The gray water holding tank is located in the underbelly of the motorhome. It is primarily used
for drainage from the kitchen and bath sinks as well as the shower.
(P-TRAPS) - Each of the sink drains and the shower drain has a water trap (P-TRAP) to
prevent holding tank odors from entering the motorhome. These traps must have water in them
to prevent odors.
When the vehicle is in motion, the water may splash out of the sinks and shower drains. When
the vehicle is stored, the water may evaporate from these traps allowing odors to enter the
motorhome. If this occurs, run water from the faucet(s) into the drain(s), allowing water to fill
the traps again.
NOTICE: Use only RV odor controlling chemicals in the holding tanks. Products
containing ammonia and petroleum will damage the ABS plastic holding tanks and
seals.
It is important that you use as much water as possible each time you flush the toilet.
This will help prevent tissue and other solids from clogging the holding tank outlet.
WASTE WATER DISPOSAL
Both of the holding tanks terminate in a valve
arrangement that permits draining each tank
separately or together. It is recommended to drain
the black water tank first before draining the gray
water tank. This procedure permits the water from
the gray water tank to wash the black water tank
residue from the drain lines.
The valves that open to release the water tanks are
called gate valves (Figure 114.1). The blade that
closed the openings in the sewer drain pipes is
connected to the T-Handle to release contents of
the tank(s) when pulled.
The sewer line must be securely capped off
during self containment use to prevent leakage of
waste materials. Do not pull the either holding
tank gate valve "OPEN" when the protective cap
is installed on the pipe.
