10 - PLUMBING SYSTEMS
It is not necessary to add antifreeze to the toi-
let since the flush valve will be closed.
Do not add automotive antifreeze or caustic
chemicals such as bleach or laundry deter-
gents into the toilet bowl or holding tanks.
Although these products may have a deodor-
izing effect, they may damage plastic and
rubber parts in the system.
NOTE:
As an alternative to totally draining
the plumbing system, you may winter-
ize tanks and lines by pumping non-
toxic RV antifreeze through the sys-
tem. This product is available from
your dealer and from most RV supply
stores. Follow directions on the con-
tainer to determine the correct
amount to use for your coach.
16. Place a bucket beneath the sewage drain
valve outlet and re-drain the sewage and
waste holding tanks of any clean water that
entered during “blow-out” procedure.
Close dump valves to prevent valve shafts
from rusting and to prevent entry by rodents
and insects. Refit the dust cap onto the drain
outlet.
Your drainage and fresh water systems are now
totally winterized.
Winterization Valve
Your coach is equipped with a manually
operated water line winterization system for
your convenience in winterizing fresh water
lines.
The system features a diverter valve and
draw tube in-line between the tank and water
pump, and uses the water pump to draw non-
toxic RV water system antifreeze into the water
lines. This feature is located in the water pump
compartment.
To Fill Lines with RV Water Line Antifreeze:
•
Turn water heater by-pass valve to by-pass
position.
•
Remove and save the protective cap from the
end of the draw tube (clear vinyl hose).
NEVER use automotive antifreeze/
coolant in your RV water system.
Auto antifreeze contains ethylene
glycol which, if ingested, can cause
blindness and can be fatal.
Leave by-pass valve handle in NOR-
MAL FLOW position if draining
water and blowing out water lines.
Place in BYPASS position ONLY
when using antifreeze solution in
water lines.
