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

the contents faster and will keep the drain

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
