Using coach air to blow out water system

Have searched here and google to find out if anyone has used their onboard air to winterize. My new to me 2004 Monaco Dynasty has a fitting for air but the manual only talks about using it to blow up toys. I've found a adapter to attach an air line to the water system and would think you could use a regulator on to bring the pressure down from 120 to 30-40 psi. Guess question is if anyone else has ever done this.

Have not use coach air but see no reason one could not, but make sure it is regulated to the 40# area.

If you have an AquaHot system, don't rely on blowing out the fresh water loop. Water can collect at a low point in the tubing. If it freezes & splits the copper, that's a $8,000-$10,000 boo boo.

I use MH air (self installed) for this purpose. I live in a temperate climate relatively speaking so I do not use anti freeze. I can move my MH to a plug in when faced with extended freezing weather.

Thanks for the reminder. I do have the Aquahot and read in the manual that you still needed to add antifreeze after blowing out the lines along with adding a little to the black/grey tanks.

I'd be kinda worried about blowing any contamination from the air system throw my water lines. The requirements for brakes and tires are totally different than potable water.

I would not use the onboard compressor to blow out the water lines. The onboard system uses a compressor with a crankcase that is kept lubricated by engine oil. Any blowby vapor that passes the compressor's piston rings will enter the air tanks and thus the fresh water system of the RV when used to blow out the lines. I carry a small oiless compressor in a storage compartment to winterize the water system when needed.

A water/oil separator should eliminate any contamination

A hundred bucks spent at Harbor freight or Lowes for a nice # 150 compressor would be a good tool to have for many things ..
But , of course taking air from the Motorcoach, will work too. Be sure to regulate the pressure as others have suggested . Using the motorcoach air for tires or air tools is not as convenient as a stand alone compressor

Thanks

Appreciate all the input. Guess I'll have to weigh price and space on weather to buy a separate compressor or rig a regulator and oil/water separator system for coach air. I'll let you know which I decide.
