The problem with winterizing is that you have to completely purge all water lines and pipes of all water or suffer the consequences. I have used the air pressure blowout method in the past, but that doesn't purge the water in the pump and pressure dome (an add-on I installed).

In addition there is the water left in the "P" traps on all of your drains and don't forget the outside shower. What about the ice maker if you have one or your water filter. You must drain the water heater and if installing antifreeze switch the bypass valve so that you don't waste antifreeze by filling up the WH.

You get the point, it is hard to be 100% sure that you have removed or replaced with antifreeze all of the possible freeze points on your coach.

PLEASE BELIEVE that you must be diligent in doing this process because if you miss something, it can be devastating and costly.

If you need further advice or guidance please ask!!
