City water valve winterizing?

[emerald 34]

So completely new to class A.
Bought a winterizing hose kit. City water valve won't accept anti freeze. Help. No manual.

Did you turn on your water pump to begin vacuum of the antifreeze? BTW…..welcome aboard.

No sir. Did not know that.

No problem. I am not sure how your class A is set up but you will want to purge your water tanks and lines of the residual water. I use a air compressor set at 45 psi and open my low drain points and fresh water gate valve then put air into the lines to purge as much as I can. Then I set my Nautilus system to winterize and start pumping in my antifreeze (RV grade) and then systematically go inside and open each faucet independently first cold then hot until the pink stuff flows. This includes any outside kitchen faucets or spray ports. You will need probably about 4-5 gallons of antifreeze to perform this. As to your hot water heater……it’s subjective whether to run antifreeze through it or not. Mine is a tankless so I just remove the drain plug and filter and drain water but not run antifreeze through it.

Good luck and it is not hard once you get the routine down. Beats paying a dealer $150 to do it being a simple thing.

I don’t winterize so I’m not as familiar with the procedure as @Germanrazor, but my 2010 Bay Star had a tank-type water heater and it had a water heater by-pass valve (as they all should) so the coach could be winterized without wasting anti-freeze filling it up - just shut off water to it and drain it, ensuring the propane is off of course. It’s my understanding that this is the prefered method.

There is a metric butt-load of youtube videos on winterizing.
