DE-Winterizing the water system-
Before using a water system that has been winterized, you should fully
rinse the freshwater tank.
Screw on the sprayer head if it was removed during winterizing.
Fill the freshwater tank and drain it by removing the drain cap.
Fill the freshwater tank again.
Turn on the pump switch and run the faucet for at least 1 gallon of
water.
Run the sprayer for about one minute.
Run the side water outlet for at least one quart of water.
The water may still have a slight RV anti-freeze odor or taste, but RV
anti-freeze is non-toxic.
If you feel the odor or taste is still too strong, drain the tank again,
refill, and run the faucet, sprayer and side outlet.
