center. They are used to drain the RV black
tank and grey water tank.
•
When connected to the sewer drain line at
a campground, keep the “black water
termination valve” closed until the holding
tank is at least ¾ full. This should provide
sufficient liquid to assist in complete
draining of the black water holding tank.
You want the black water holding tank
nearly full so that weight and gravity will
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 are
not warrantable.
Maintenance
The termination valves require routine
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.

TTACHMENTS
You will need a flexible RV sewer hose to
connect the RV drain valve to the
campground sewer line or dump station.
Contact your dealer to discuss and purchase
(if needed) a heavy duty sewer hose, sewer
hose extension valve adaptors, sewer
connectors, house adaptors and other various
attachments. Do not remove the following
label from the sewer hose dust cap:
Fig. 8.10 Cap must be securely
For sanitary purposes, you may want to use
disposable non-porous gloves and boots that
can be rinsed off when dumping the holding
tanks.
To attach the sewer hose
Fig. 8.11 Sewer hose dust cap
1. Level the RV.
2. Before connecting your sewer hose
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
