APPLIANCES & INTERIOR FEATURES
8-10
causing a slight increase in water pressure. This
may cause the P-T valve to “weep” until the air
pocket is manually replaced.
OPERATE THIS VALVE ONLY WHEN
THE WATER HEATER AND COOLING SYS-
TEM ARE COLD!
To Replace the Air Pocket:
1. Turn off the water heater switch and incom-
ing water supply (city water and/or demand
pump).
2. Open a faucet in the motor home to relieve
water pressure.
3. Pull the handle of the P-T valve straight out
and allow water to flow until it stops.
4. Let the handle of the P-T valve snap shut.
5. Close the faucet and turn on the water supply
before switching the water heater on.
Manually operate the pressure temperature re-
lief valve at least once a year.
Anode Rod Replacement
The drain plug is also a replaceable anode rod,
which protects your water heater from corrosion.
It serves as a “decoy” for harmful elements that
could deteriorate the tank.
Check the anode rod at least once yearly. If the
anode rod is mostly eaten away, put in a new one.
Hard water with high levels of iron and/or sulfate
will eat away the anode rod more quickly, so
more frequent inspections may be needed. Anode
rod/drain plugs are available from your Winneba-
go Industries dealer or an authorized Suburban
service and parts center.
Do not operate the water heater without the
anode rod protection. Do not replace the anode
rod drain plug with a drain plug that does not con-
tain an anode rod.
WATER HEATER BY-PASS VALVE
Your coach is equipped with a water heater
by-pass valve for easier winterization of water
lines using RV antifreeze. The valve is located
behind the access panel on the side of the refrig-
erator cabinet toward the front of the coach.
NOTE: Your coach is not equipped with this
valve if you have the optional automatic
winterization system.

CAUTION
Leave by-pass valve handle in NOR-
