If the motorhome does not have a black tank rinse system,
you can use water from the toilet bowl to rinse the black
holding tank:
1. Ask your partner to flush the toilet several times to
duplicate the action of black tank rinse system. Do this
immediately after dumping the black tank and while
the flexible sewer hose is still connected to the sewer
outlet of the motorhome and to the dump station inlet,
and while the black termination valve is open.
2. This rinsing process may need to be done several
times. Please be sensitive to others waiting to use the
dump station facilities.
Winterizing the Water System
Automotive antifreeze (ethylene glycol) and windshield
washer antifreeze (methanol) are poisonous. Never
use these products in your fresh water system. These
products are harmful and may be fatal if swallowed.
Only use biodegradable RV antifreeze to winterize your
motorhome’s fresh water system.
WARNING
WARNING
Antifreeze can be damaging to internal components of
the water heater. For proper water heater winterization,
drain the water heater tank and bypass the water heater
inlet before adding antifreeze to the fresh water system.
NOTICE
NOTICE
Preparing for colder weather or storage is a very important
part of routine motorhome maintenance. The motorhome
should be winterized at the end of the camping season, or
when exposed to temperatures that will fall at or below
32°F (0°C). Repairs due to freezing water damage are not
covered by warranty. Add only RV antifreeze to the fresh
water system to ensure freeze protection. It may be easier
to winterize the motorhome with another person assisting
you.
1. Level the motorhome and drain the fresh water plumb-
ing system by opening all low-point drain valves and
draining the water heater.
2. Remove or by-pass the potable (drinking) water filter
(if equipped).
3. If you have a dishwasher, ice maker, or washer follow
the appropriate appliance manufacturer’s instructions
pertaining to winterization (and de-winterization):
• Disconnect and cap (or by-pass) the refrigerator
ice maker inlet water line (if equipped)
• Disconnect and cap (or by-pass) the dishwasher
inlet line (if equipped)
• Disconnect and cap (or by-pass) the clothes wash-
er inlet line (if equipped)
4. Turn OFF the water heater switch on the monitor or
multiplex panel.
5. Turn OFF the gas valve at the water heater or turn
OFF the tankless water heater switch.
6. Turn the water heater bypass valves (if equipped) to
the BYPASS position. A tankless water heater may not
have bypass valves.
7. If the water system includes a water valve panel, move
the valves to the WINTERIZE position, as shown on
your water system label.
8. Close the low point drains.
9. Attach a hose to the city water fill and insert the other
end of the hose into a gallon container of RV anti-
freeze (this quantity should be enough to winterize the
motorhome). To assist the siphoning process, put the
container on a surface approximately two feet above
ground level and use a short length of garden hose (15
feet or less).
10. 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.
11. Open the hot water side on all faucets (kitchen, lava-
tory, shower, and exterior shower) until RV antifreeze
begins to flow continuously.
12. Close the faucet hot water lines and repeat with the
cold water lines on all the faucets.
13. Flush the toilet a couple of times until you see anti-
freeze in the bowl.
WHEN YOU ARE DONE ADDING RV
ANTIFREEZE:
14. Remove the water hose from the container of RV
antifreeze.
15. To prevent staining, wipe the RV antifreeze out of the
sinks, shower (or tub) and toilet using a soft, dry cloth.
