Blacky,
I put a 3 way valve where the water line comes out of the water tank.
I put a quick disconnect fitting for my air line on the other side.
I hook up my air line from the compressor and regulate it at 40 psi.
This blows out all the air as I go around and open up the faucets.
Also take a small screw driver and push open the check vavle on the street wter connection.
I also put a 1/4 turn shut off on the hot water heater to make it a little easier to drain. Get a plastic ball valve because you need to do a little shaping of it.
I had heard that a guys wife hated the after taste of the pink stuff in the water lines and ended up having to sell the trailer, they bought a new trailer and the following year he winterized the pipe with a gallon of vodka, a little more expense but the wife was happy.

Sorry for the delayed reaction here, I just slipped on by this thread somehow after posting that last one. Thanks csshafer, I was not aware that you can limit the output. That would be a great help! I will have to run up and take a look at mine when I get off line here!

I could not find a reducer 3/4" male pipe thread to 1/4"pipe thread female so I used a 3/4" male pipe thread to 1/2" female pipe thread reducer then a 1/2" male pipe thread to 1/4" female pipe thread reducer to screw the 1/4" male pipe npt fitting in to. I expected to be able to find a male or female 3/4"pipe thread adaptor with an npt connection ready made but couldn't.

When you blow out the lines it would seem to put some moisture in just by the nature of a compressor. Maybe someone should make an adapter so a shop vac could be hooked up to suck out the remaining moisture in the lines.
