Never have winterized one of these. My Royales have had one of these valves at the water heater. I blew it out days ago. But needed to get anti freeze in the water pump. So I put a hose on the pump intake. Put the other end in a gallon of anti freeze. Seems that all the anti freeze is going into the water heater. The system is now protected. But would like to have seen the anti freeze at the faucets. Snow tonight. 15 degrees tomorrow night. Started to cool down. Bob Dunahugh
Winterizing a GM interior GMC. No water heater shut off valve?
- Thread starter Bob Dunahugh
- Start date
I don’t have a bypass and haven’t been motivated to install one, so I bite
the bullet and pour 7 gallons of RV antifreeze into my freshwater tank. The
pump fills up the water heater and then the hot water plumbing, and then I
can run the cold taps to fill them up. I then drain everything. Yes, it’s a
waste, but a pretty small one. I use the 8th gallon to fill the P traps and
pour the remainder into the toilet. Then, I run the macerator to distribute
the pink stuff into the macerator and hose.

Bob,
No pink in faucet, you are going to have a problem. Your going to need a bypass on the water heater or pump in 5-6 antifreeze to fill the
water-heater. Or blow it out with air, but that is not fail safe. Some toilet valves(dometic 310). Wont blow out.
I filled up my fresh water tank today. Tossed a big scoop of rock salt down the toilet and turned on the furnace. Will be staying in and using the
coach this weekend.

I’ve installed a water heater bypass and fresh water tank bypass (at the pump). I bypass and drain the heater - then drain and bypass the water tank. I then pump in enough AF to get pink at all taps/valves. Enough AF goes down the drains to protect them (but we rarely freeze in the winter). This year - I’ll need to also ensure the black tank gets enough AF to protect the macerator.
As others have said - if don’t bypass the water heater, you’ll need enough AF to fill it, before you get pink at the faucets (I don’t want AF in my water heater and don’t want to “waste” that much AF).

I have been doing it your way for the 37 years I have owned the GMC.
Prior to this I used to blow out the lines with air in my Dodge Travco but once had a copper line rupture from freezing of a low spot in the line where water collected and the air just blew past it.
I winterize using one gallon of RV antifreeze with enough left to pour into the drain traps — don’t forget the shower drain.
There are two types of pink RV antifreeze. One is made of propylene glycol. The other contains ethyl alcohol. The alcohol one is cheaper but the propylene glycol is much better. Read the label.
The water tank and water heater bypass valves are the way to do things. You can buy them on Amazon or from about any RV parts store or from Applied GMC.
