6. 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).
7. Open the hot water line on all the faucets (kitchen, lavatory, shower and
outside shower) until RV antifreeze begins to flow continuously.
8. 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
9. Remove the garden hose from the container of RV antifreeze.
10. 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.
BLACK/GREY WATER SYSTEM
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 motor home. During travel, water from the P-traps may spill and permit odors
into the motor home. 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).
BLACK/GREY WATER HOLDING TANKS
The weight of the holding tank contents is not calculated into the motor home
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 motor home GAWR or GVWR.
WARNING
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
vehicle handlin
