winterizing finality

[citiznmikem]

I have winterized the lines of my trailer, the toilet, inside shower, outside spray port, left anti freeze in the traps, toilet bowl, but I just read a blurb yesterday about putting anti freeze in the city water inlet valve. when I depress the button behind its filter screen, some water came out, but I can't figure out how to get a/f into it. Can I suck anti freeze into the inlet side of water pump and backflush line to city water inlet that way, or is there a check valve involved. Any advice would be appreciated as I'm running out of time with this very recently purchased trailer.

Where is this valve you are talking about??

This one-way valve is inside your city water inlet. It allows water to flow into your RV and prevents water from flowing out when you use your onboard water pump. It can trap water in the tubing leading to the RV plumbing if it is not installed so water drains out when you open your low-point drains.
I've never bothered to push it in to open it manually because often doing so causes it to stick open or break. I've gotten by for several decades without bothering it and never had it freeze and break anything.

I found it on eBay for $4.95 plus $3.95 shipping. They have other listings for this item at different prices. It shipped quick, and I had it in about 2 days.

We have a jump box with a compressor. Just hooked it up and evacuated the water out of the lines. GREAT little gizmo to have on hand!

G'luck!

That's twice what I paid for mine,also brass fitting. I paid $3.99 at a local RV supply shop.

I finally found a generic manual online and it states to turn on the water pump to pressurize the fresh water system, then... "with the system pressurized, press the check valve in the city water inlet until you see anti freeze flowing out, also open the lowpoint drains until you see anti-freeze flowing out" I'll try that in the morning and see if it works. Thanks everyone.

Exercise caution pushing the valve in, often it causes it to break-cheap plastic item.

Since I winterize using my water pump it is really a no brainer. When I press the little button I try to remember to stand clear as it will not dribble, it will spurt and usually the back end of the spurt is AF.

Do you have the manual, and if so, did it recommend adding af to the city water inlet? I've never done this to my previous mh nor my current tt and never had a problem. Might be overkill.

I have never addressed this either. Never thought of it
and never a problem. You most likely are fine.

"Burping" it like you have already done is all that is required.

I would have guessed that the low point drains would have removed any water from that location.

I just blow some air into that connection and put pink stuff everywhere else. CW has a fitting that screws into the connection with an inlet suitable for a compressor. Actually, a tire pump might work also.
