SECTION 8
PLUMBING SYSTEM
5. Move the valves to the “Sanitize/Winterize
Lines” position. The low point drains must
be closed for the antifreeze to siphon
through the lines.
6. Insert the garden hose into a container of
RV antifreeze solution (this quantity
should be enough to winterize the RV);
attach the other end to the city water
connection.
To assist the siphoning process, put the
container on a surface approximately two
feet above ground level.
7. Turn the water pump ON.
If the water pump fails to self-prime,
temporarily open the low point drains
(close the low point drains as soon as the
water pump primes [RV antifreeze will
begin draining out] and before continuing
to the next step).
8. Open the hot water line on all the faucets
(kitchen, lavatory, shower and outside
shower) until RV antifreeze begins to flow
continuously.
9. Close the faucet hot water lines and
repeat with the cold water lines on all the
faucets. Do not forget to run RV antifreeze
through the toilet.
When you are done adding RV antifreeze
10. Remove the garden hose from the
container of RV antifreeze.
11. To prevent staining, wipe the RV
antifreeze out of the sinks, shower (or tub)
and toilet using a soft, dry cloth.
To reduce the chance of contamination,
prevent the garden hose from coming into
contact with the ground. If needed, contact
your RV dealer for assistance.

Water from the sinks and shower (or tub) flow
into the gray water (or waste water) holding
tank. Water from the toilet will flow into the
sewage (or black water) holding tank. Certain
floor plans may also have the lavatory
draining into the waste (black) tank.
Drain pipes
The drain pipes have 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. These odors
come from food particles decomposing in the
tank. 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 Jayco independent dealer.
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).

Never travel with full black or grey water
holding tanks. This not only wastes your
fuel but depending on the location of the
tank(s), it can affect your tow vehicle
handling characteristics.
The weight of the holding tank contents is not
calculated into the RV cargo carrying capacity
(this extra weight would reduce your available
cargo capacity). Traveling with full holding
tank(s) could possibly cause you to exceed
the individual tire ratings and/or the RV
GAWR or RV GVWR. Potential damage to
suspension components, such as springs,
tires and axles, could result. If your RV
holding tank(s) are located behind the axles,
the weight of the full tank(s) will reduce the
hitch weight. Motorhome sway and other
handling difficulties can be the result of the
hitch weight being too light.
Dump the gray and black water holding tanks
before traveling to avoid carrying unnecessary
weight. If you are dry camping and cannot
immediately empty your holding tanks, reduce
