Keystone RV Forums - View Single Post - Winterizing water line between tank and pump

I usually go through 8L (2 gals approx.) by time I pour some antifreeze into the toilet bowl, all the P-traps, and pump some into the FW city water intake and black flush inlet. I don't put any in the FW or HW tanks.

It's not expensive so if you buy too much, any left over can always be used for next year. Better to buy more than have to stop in the middle of winterizing and run out and get another gallon.
