If you leave the Aqua-hot on and the coach plugged in, why do you winterize at all???

I have winterized with air for the last 3 years.....pressure at about 40-50 psi, open all faucets, shower, run washer (if you have one), dishwasher, and don't forget the ice maker. I drain the fresh water tank and open the low air lines with slight pressure after I've done the faucets.

I still put some pink stuff in all the traps.

Don't forget to remove any water filters in the coach.

I also set my aqua hot at 50 degrees since I have power in our unheated barn. Then we simply put in about 50 gallons of water the night before we leave in the winter, xmas eve, and hit the road. De-winterize at the first warm stop.

just a habit I guess. I have a whole house generator on the house in case of a power outage. It really takes me about 10 minutes to blow it out...at least I don't use the pink stuff anymore.....LOL

I use a small portable compressor I got from Harbor Freight. It has a regulator on the output that I can set as low as 5 psi if I need to.

Since water from CG systems is often supplied at 60 psi or more, I use about 35 psi for winterising, so I know I'm not going to blow anything apart. Our MH doesn't have a dishwasher (other than me) and no clothes washer (other than an en-route laundromat).

After draining the water heater and shutting it off with the by-pass valve, I put the compressor onto the water fill port with an adapter that connects a Schrader tire valve to a water hose. With the compressor's outlet pressure at about 30 psi into the water system, I then go around and open the faucets, including the outside shower and the toilet, and let the air blow through. Once it's done, I put the "pink stuff" into the P-traps and I'm done. I figure the small amount of water (maybe two pints) going into the 40-gallon waste tank can freeze without causing any damage.

We rarely get winter days around here where the daytime high temp stays below freezing and the overnight lows are in the mid-20's for just a few days in a row. Thank goodness we aren't in a place where overnight lows are closer to minus 20! We ex-pat British wimps couldn't handle that!

If you have a clothes washer or dish washer, they can't be winterized by using any kind of compressed air. Antifreeze must be used.

Good Luck!

What about the oil from the compressor. shouldn't it be an oil free compressor?

You can pick up an inexpensive air regulator and set it for 40-50 psi. Then you will not damage your water system.

I wouldn't use the on board air compressor or any other air compressor. Use the blower end of a shop vacuum. It has enough pressure to blow the water out without damaging the plumbing. I have also used my shop vacuum on my pool every fall for over 25 years and haven't had any problems.

incidentally, I also use the red RV antifreeze to just make sure no remaining water stuck in some low spot will freeze and damage something. I also pour at least a quart into each tank for the same preventive reason.

My concern would be with the 120 plus PSI in the fully charged system. Maybe bleed down to abt 40psi and you should have enough air to blow out the lines. Doesn't take much.
