Winterizing with Antifreeze Method
Requires non-toxic RV antifreeze in the water lines and does not require any special tools.
Use ONLY RV ANTIFREEZE in your fresh water system for freeze protection. No other
product or commodity should be used.
1. Turn power to the water heater OFF (both electric and LP Gas switches).
2. Level the recreation vehicle and drain the fresh water plumbing system (see Draining
the Fresh Water System).
3. Set the water heater bypass valves to
BYPASS
– Refer to appropriate water heater
bypass diagram for your model.
4. Make sure the “fresh water tank drain” and “low point drains” are all closed.
5. Refer to
Fig 1 : The siphon valve should be turned ON. The water tank shutoff valve
should be turned OFF. This will prevent antifreeze from entering the water tank.
6. Place the end of the clear plastic hose into a container of RV antifreeze.
7. Turn the water pump switch ON. Antifreeze will siphon into the water lines when a
fixture is opened. To aid in siphoning, place the antifreeze container on a flat surface
2 feet above the ground.
8. Beginning at the fixture location farthest from the pump (which would include the out -
side shower (if equipped), open the hot faucet until antifreeze runs out, and then shut
off the faucet. Open the cold faucet and shut it off when antifreeze runs out. Repeat
this procedure for all hot/cold fixtures. This would also include an outside kitchen sink
if equipped.
9. Hold open the lever on the toilet until antifreeze runs into the bowl.

siphon valve OFF.
11. Pour 1 cup of RV antifreeze into all sink drain P-traps.
NOTE: Antifreeze should never enter a tank type (storage) water
heater.
