Plumbing Systems
Dump station locations
Dump station locations throughout the United States and
Canada can be found on many websites and publications
including Woodall’s, Rand McNally Camp Guide, Good Sam
Camp Guide, KOA Kampgrounds Camp Guide. Some gas
stations also have dump stations.
If you need assistance with the purchase or installation of a
sewer hose or hose extension, Please contact your dealer.
Vents & Vent Pipes
For the plumbing system to drain properly, the vents and vent
pipes must release air from the grey and black water holding
tanks. Always keep the exterior vent cap on the roof clear of any
obstructions. In some models the vent pipe may be a
wet vent
allowing water to drain downward with air flowing upward in the
same pipe.
Drain Pipes With Dry Sealing Valve
Your RV may be equipped with a dry sealing valve to prevent the
escape of odors from your waste system and eliminate the need
for P-traps. Should the RV drain piping system become clogged,
a mechanical clean-out tool is used to open the drain pipe.
•
It is important to remove the dry valve before
passing the clean-out tool through the piping.
•
Passing a mechanical clean-out tool through
the waterless valve may cause damage to the
internal seal that may potentially allow sewer
gases to escape to the RV interior.
Drain Pipes With P-Traps
The drain pipes may be equipped with a
P-trap
installed to help
prevent odors from escaping into the RV. During travel, water
from the P-traps may spill and permit odors into the RV. By add-
ing 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.
Remove the waterless trap
before using mechanical
drain cleaning devices.
Waterless trap can be
damaged.
