Winterizing coach what do you think?

[Dave1956]

Thanks for all the great responses! I will take a long look at the coach this weekend and see what access I have to the pump. We will be using the coach several time coming and going from Colorado to Texas, so I need to winterize a couple of times. Thanks.

I like this adapter for the city water connection that allows the compressor to run without having to stand there and hold the air hose.

That limits the amount of yucky taste you have to put up with in the spring and protects the pump. On my current rig, I don't use one because the drain line method on my Chinook actually involves turning a couple of ball valves and the pump pulls water from the tank and the adjacent line through the drain valve and will do so until it runs dry.

Oh - and concerned about running your pump dry? At least in my case, Shurflo says it is safe to allow it to run dry. Classic Series Water Pumps - SHURflo

Been using the Air Pressure system on my Old Beast the last 14 years and have never had issues- - 40 wind chills last year for over a week.
