2.) Turn water heater bypass valve to ‘bypass’ position.

3.) Drain water heater.
4.) If you have a water filter system installed, remove the

filter from the assembly and discard. (You will need to
purchase a new one and install it when dewinterizing
your unit.)

5.) Fill the tank above minimum water pump operation level

with the RV antifreeze. (Use of a long funnel may be
helpful.)

6.) Turn the pump switch ‘ON’ and open the cold water

faucets. Repeat for the hot water side.

7.) Flush toilet until antifreeze is visable inside the bowl and

pour one gallon of antifreeze down the toilet to winterize
the black holding tank.

8.) Pour antifreeze down each shower/tub, lavatory sink and

kitchen sink to fill p-traps.

related sink drain.
