winterizing

[huskyfan68]

I am trying to winterize new camper since temp is dropping in NJ-
I drained all lines + water heater- I then hooked my compressor up to city water inlet- With it connected with at least 30PSI- I never felt or heard any air coming out of the faucets- Is this normal? Opened all the taps and nothing- So I am wondering if everything is out....

Yup, and you are less likely to leave water behind and have an expensive repair. Don't forget, even if you are successful in blowing out the lines, you need to add antifreeze to the pump and to the drains.

Agree. IF you use your freshwater pump you need to get pink in it. That is why after the walkthrough, and first time winterizing. I don't use the fresh tank, or pump.

Running the pump dry for a couple minutes is sufficient to winterize it--or at least that has yet to fail me. RV water pumps can be run dry without harm, though I wouldn't suggest doing so for hours and hours.

Cool. Good to know.

Pink is not easier for all. it isn't for me. My pump has no winterizing kit, and you can't get to it to unhook the hose from the tank, and hook up one to the pink bottle. So after the first time having to put enough in the fresh tank for it to be picked up. I now only use air. Only take a few minutes, and you don't have to bypass the water heater. Which on my TT is also hard to get to.
35 PIS at the city water inlet, Go to each faucet in turn. let it blow until no more mist comes out, Pour a little pink in the traps, and on tolite seal, and you are done. Can winterize with about 1/2 gal of antifreeze.

Did you flip the valve from your internal pump to city water hookup?

I once saw someone hook up the air hose to the Black tank flush... Just saying

You ought to hear the air coming out somewhere, even if it is going into the tank. I’d winterize with antifreeze, like today, since temps may hit single digits in parts on NJ tonight.

Close low point drains. Bypass WH. Close all but one faucet. Close that faucet and move to the next one open/close and so on.

The air going into your tank will pressurize it and hence backward up the lines to your various outlets(don't forget the outside shower!).

When I do my air blowing in the fall I only open one outlet point at a time. I used 25 psi. I can feel the air come out. So I do not have the tank valves open at the same time as the kitchen faucet for example. I do the tanks last.

I think you will be safe with this approach.

With the low point drains open the air went out them.

It's possible the air is going into the tank. Hook air directly to the water pump outlet line - or any of the faucets- and make sure the WH is on bypass.
