Pressure-Temperature Relief Valve
(Lift handle only when water heater is cold)
• Reinstall the water heater drain plug and
close the P-T Relief Valve when drained.
Close All Drain Valves
12. Close all waterline drains and tank drain
valves to avoid contamination by dirt, insects,
or rodents.
13. Pour about one cup of RV antifreeze down
each drain for the galley sink, lavatory sink,
and shower/tub. This fills the drain trap pipes
to prevent holding tank odors from entering
the coach during storage.
Dump and Clean Holding Tanks
14. Completely drain the sewage and waste water
holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the sewage drain outlet and sewer
hose.
15. Close dump valves and refit the dust cap onto
the sewage drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
