force the contents of the holding tank to
drain properly.
□ If you are at the campground for an
extended period of time and the sewer
hose is connected to a dump site you can
leave the grey tank termination valve
partially open so it drains as you use it,
but remember to NEVER do this with the
black tank termination valve.
There must be sufficient liquids in the holding
tanks to prevent solids from hardening and
potentially cause obstructions. Repairs due to
improper use of the RV termination valves is
not warrantable.
Maintenance
The termination valves
maintenance. Each termination valve has an
O-ring which seals both sides of the sliding
valve. Contact your dealer for a service
appointment if you are not comfortable
performing this maintenance.
□ If the sliding valve does not close properly,
remove the 4 bolts that hold the valve
housing together. Clean and lubricate the
O-ring and moving parts using a silicone
lubricant.
□ The O-rings must be replaced every few
years as they wear and become aged.

2. Before connecting
remove the twist-on bayonet dust cap
(also referred to as a waste cap) that is on
the valve assembly.
3. One end of the sewer hose attaches to the
valve outlet with a twist-on bayonet hose
adapter.
4. The other end of the sewer hose attaches
to a sewer fitting for connection to the
ground level sewer. Some sewer fittings fit
loose while others form a gas tight seal
which is now required in many states.
Once the hose is properly connected on both
ends, dumping of holding tanks requires only
pulling the handles of the termination valves
to the open position. Always drain the black
water holding tank first so the following grey
tank waste water can help rinse any solids or
debris from the dump outlet and sewer hose.
