I blew out my system last year for a change. I made an adapter to hook my compressor to the water hose connection on the trailer and just turned down the pressure from the compressor to 50 psi, opened all the taps one at a time until they blew clear as well as the toilet. I also have 2 caps under the trailer that are the lowest points in the system, pulled them off until there was no water,pull the plug on the heater and let the water drain.Poured some anti freeze down the drains and good to go, takes all of about 15 minutes.
