City Water Flange
Whilst winterizing my TT, I made sure that the RV plumbing anti-freeze went everywhere it needed to go, including the city water
connection.
How did I do that, you ask?
Well, with the system almost fully pressurized with the on board water pump, I pushed in the check valve of the city water connection which forced anti-freeze into the line and out the valve.
Great!! Worked like a charm!
Except that in doing so, the internal "O" ring was dislodged thus rendering the check valve kaput.
So I decided to do some NDT on the valve to see the what for.
Kidding.
Once apart, however, it still leaves me shaking my head to WHY the "O" ring would get dislodged. It sits in a very deep groove of the actual valve.
Anyways....either way.....I'll be more careful next time with that step of winterizing and will install a new flange in the spring.
