City water inlet ?

[CLewis]

This is the 1st RV we have had that had a antifreeze inlet just below our city water inlet. My question is we winterized our RV yesterday thru this inlet. Do we have to run antifreeze thru the city water inlet?? On our other RV's we pumped it thru the system either by hand pumping thru the city water inlet or there was a hose by our water pump and we pumped it thru that way. Just wondering. Thanks Cyndi

shouldn't be any reason to, especially if you blew it out with air first. The purpose of the antifreeze inlet is to use the on-board pump to pull antifreeze into system, where city water doesn't need pump

Dave,
We didn't blow out the lines. We just ran antifreeze thru them.

I think you need to "burp" the city water inlet so the connector/check valve doesn't freeze. I found a YouTube video that shows how.

I guess there is a small possibility, depending on how system is set up, there could be a bit of water in the line between the city and switching valve

[davel1971]

did you bypass water heater, drain water heater and low point drains before you pumped antifreeze through?

[CLewis]

Yes we did bypass the water heater and drained it and opened low point drains,.

If you look at the city inlet there is a hose washer with a screen on it take that out then look in you will see a small button like piece of plastic, push it with your finger but make sure your out of the way because it may spray you. You should see a little antifreeze drip out. If you blew it out you should be ok but it's nice to know you are defiantly ok.

Yes! Youroo!!

When i "burped" mine, pressing the plastic button did nothing with my water pump turned off, when I turned water pump back on and pressed it, then I got the spray you talk about.

If there is pressure it will spray you. But without you may get a dribble

Thanks everyone. My husband pushed it good thing he stood to the side. He got a big spray of water then he saw the antifreeze. RV all done now just waiting for the Jersey freeze and for 2015 camping season - Can't wait!!!
