SECTION 7 –
PLUMBING
Using On-Site Sewer Hook-Ups
The drain hose may remain attached to the
dump outlet and be routed out the bottom of the
compartment while the motor home is parked and
connected to an on-site sewage hook-up.
The center outlet section may be swiveled
downward for better hose alignment and
drainage.
NOTE: Always keep service access passage
closed while utility connection is not in
use.
When using a sewer hook-up, keep the dump
valves closed until a tank becomes full or when
preparing to leave the site. This keeps the solids
in suspension, allowing them to be carried out
with the liquids when the dump valve is opened.
If the valve is left open, the liquids will drain off,
leaving solids in the tank. Should this
accidentally happen, disconnect the hose, fill the
tank about half full with water, and drive a few
miles to dislodge the solids. A few starts and
stops will aid in the process. Then reconnect the
hose and drain in the normal manner.
Holding Tank Level Indicators
See Systems Monitor Panel in Section 4–
Appliances for further information on the
monitor panel and checking tank levels.
See Specifications in Section 1–Introduction
for tank capacities for your model.
WATERLINE & TANK DRAIN
VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the
following illustration.
Drain valve locations are listed in the Water
