Winterizing the line from the park water

[Ham_Bone]

It used to be that when one winterized an RV they had to make sure that the anti-freeze being pumped into the water system by the water pump also came out (backwards) through the "park" water inlet. Usually this was done by defeating the one-way valve at the hose bib fitting and allowing the anti-freeze to come out. Today I winterized my trailer exactly per the manual. There was NO mention of doing this, so I didn't. Put my mind to rest and tell me that step isn't done any longer.

I never had antifreeze exit through the fitting like that. I usually just hook up a hose to my city water fitting and run a little antifreeze into it when I finish doing all of the stuff inside as a precaution. There have been years where I didn't even do that and I was ok. Getting more cautious in my old age.

Good luck,
Don

I been RV'ing since 2007. I fail to see why everyone goes to all the trouble of using anti freeze. What I've been doing without any problems, if we're staying in the RV in freezing weather, I'll just let a cold water valve drip all night long, if the water is flowing through the lines it doesn't freeze. If the RV is in storage I just drain the water tank, the hot water heater, and open the two line drains, all the water's drained out. 5 minutes, zero cost.

It may be unnecessary if your city water inlet runs downhill to a low point drain before going back up inside your camper. The only way to know for sure is to check, but that usually means accessing the underbelly to do so.

I ran into the same dilemma. I winterized per the manual, and this wasn't mentioned. After looking back through this site and seeing that, I went back out and popped the screen off the city water inlet. Sure enough, the little button to defeat the check valve was there, so I flushed a little more anti-freeze out of it.

I have no idea why they wouldn't include that in the manual if it was necessary, but I figured it couldn't hurt to do it.

The check valve could be damaged when doing this step.

I will second that...
Here in Ontario, Canada, we have up to 6 months of the year with below freezing temperature

The check valve won't get damaged if you turn off the pump and open a faucet to relieve the pressure. You only need a few drops of the pink stuff to come out of the check valve.

im thinking if you connect the out side hose connection to the park connection if the connect would force anti freeze into the line ? when im home I use compressed air to blow out that line and the black tank flush . but I haven't had to do that for the last 3 years as we go south for the winter your thoughts on this big bill

So Youroo, Just cause I now live in Fl. what makes YOU think I don't RV up North, and for your information it does freeze here in Northern FLorida.
Besides, Water freezes at 32 degrees. It doesn't make any difference if it 30 or minus 30, the water has frozen, expanded and turned to Ice.
Again why don't you, and others do like I do and just drain your RV's water lines, water heater, tanks, etc when storing your RV's? It's Easier and Less Expensive than buy anti freeze and pumping into your lines.
