By adding water and using a RV approved deodorizing
agent you will dissolve the contents faster and will keep the drain lines and tanks clean and
free flowing. These chemicals are available at an RV supply store or your dealer.
Drain pipes With Dry Sealing Valve (If So Equipped):
Your RV may be equipped with a dry sealing valve that prevents the escape of odors from
your waste system and eliminates the need for P-traps.
Should the RV drain piping system become clogged and a mechanical cleanout tool is used
to open the drain pipe, it is important that the dry valve be removed before passing the
cleanout tool through the piping.
Passing a mechanical cleanout tool through the waterless valve may cause damage to the
internal seal that may potentially allow sewer gases to escape into the RV interior.
A label has been placed near the location of the waste valve that reads as follows:
USING MECHANICAL DRAIN – CLEANING DEVICES
Vents:
Another important part of this system is the vent pipes and vents that release air from the
grey and black water holding tanks. The exterior vent cap is attached to the roof and must
be kept clear of obstructions to perform as intended. On some models, the vent pipe may be
part of the drainage system referred to as a "wet vent" (water flows downward as air flows
upward in the same pipe).

When connected to the sewer drain line at a campground, keep the "black tank drain" valve
closed until the holding tank is at least ¾ full. This should provide sufficient water to assist
in complete draining of the black water holding tank. Repeat as needed. Never leave the
black tank drain in the open position continuously when connected to the campground sewer
system.
Whenever possible, do not travel with waste in the holding tanks. Liquid or
debris in the holding tank(s) may affect the towing characteristics and may
result in property damage or personal injury.

There are labels on the exterior of the RV indicating the location of the grey tank drain and
black tank drain (also called dump valves). 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.
1. To make drainage easier, level the RV.
2. Remove the sewer hose housing dust cap, and
attach the sewer hose (customer supplied).
