It's really not the air pressure that moves the water out, it's the air FLOW. As soon as you open a faucet, pressure drops very quickly, unless you have a VERY large capacity compressor and/or air tank.

Thus the reason we all say 'REPEAT'

My point is that you don't need a check valve to " hold" the pressure.

And my point it that it sure makes it easier to do it by yourself.

Then yours must attach to the air hose. Mine does not.

winterizing

If I missed something, excuse me, but the little part that connects your air compressor to the city water connection is available at most any RV parts counter for under $10 so your compressor stays hooked up and running while you go around opening and closing valves.

It takes 2 gallons of anti freeze to do the lite, so I do not bother with the air.

Mine has no way to leave the air hose connected unless someone stands there and holds it. I use the rubber tipped blow nozzle to pressurize the system. Guess I could get brass fittings and rig it with a quick release but just never needed to. The whole process takes about 10 minutes.

We don't really have winter so we still use ours during the winter months. We just blow it out between trips and don't mess with antifreeze.
