Iflyfish Posted April 23, 2017 Share Posted April 23, 2017 My '87 Sunrader has anti-freeze in the fresh water tank. I used to winterize my Winnebago View by putting anti-freeze directly in the system via the water pump, bypassing the fresh water holding tank. Two questions. 1. How do I clean the tank/system of anti-freeze, the color is nice for a cocktail with an umbrella in it but I'll pass on it. 2. How do I add anti-freeze to my 87 Sunrader water system without putting it in the fresh water tank. Thanks, Iflyfishwithanti-freezecocktailinhand Quote Link to comment Share on other sites More sharing options...
WME Posted April 24, 2017 Share Posted April 24, 2017 (edited) Well try flush with fresh water, next bleach 1/8 cup per 5 gal, fill 3/4 full and drive around to slosh the bleach mix everywhere, Next a box of baking soda in a 3/4 tank and drive. Finally a 3/4 tank of just water and slosh it around. The quantities of "stuff" is way overkill for just normal spring cleaning because of having anti freeze in it. I REALLY hope it was RV anti freeze in the tank and not auto engine anti freeze. Edited April 24, 2017 by WME Quote Link to comment Share on other sites More sharing options...
Maineah Posted April 24, 2017 Share Posted April 24, 2017 You can add a valve tap to the water pump intake this will allow you to pump antifreeze into the plumbing. You will also have to add a valve to the hot water tank to by pass it or you'll use 6 gallons of the stuff. Or use air pressure to blow the lines out (I use the city water port with a home made fitting and a short hose) you will still have to drain the tank and pump a little antifreeze into the pump but when I do mine I only use about a pint of antifreeze for the entire system. There is no real way other than drain the fresh water tank add water, pump the lines out with the fresh water and repeat that is why I use air to blow the lines out I can taste the antifreeze for weeks other wise, it's non toxic but not real nice stuff.

It is RV anti-freeze in the fresh water tank. Great input! Iflyfishwithcleanwatertank Quote Link to comment Share on other sites More sharing options...

Excellent!! I appreciate your thoughtful response. I am sure this is how my View water system was configured as this is how I used to winterize. I will follow up with your great idea! Thank you.

Leave the low point drains open, shut the suction valve on the pump intake then suck up about a pint of antifreeze through hose fitting behind the valve and call it a day.
