Camping in a Class B when it gets cold...

I agree. I installed a "T" fitting and valve with a short piece of vinyl tubing on the input side of the water pump. After I blow out the lines thoroughly and close off the tanks, I stick the end of the vinyl tubing into a jug of antifreeze, turn on the water pump and pump just a few cups of antifreeze into the system for my piece of mind. I still haven't used up my gallon of antifreeze in several years.

Do you happen to remember whether the damaged valve was left open or closed? I always leave mine open, and have wondered whether it matters or not.

I thought I was being smart last fall and left my faucets open after winterizing to avoid cracking. This spring I was filling my freshwater tank and finally noticed that my kitchen sink faucet was still open with water running but the damn corian sink cover was still on. It took awhile to clean that mess up. I will probably close the faucets from now on. LOL

Closed.

It broke on the shower fixture side of the valves, so only leaked (behind the wall) when the shower valves were opened. Didn't find the leak until we were at a campground & taking a shower, of course.

My guess is that leftover water ran back down the shower hose into the valve after blowing it clear, then froze and cracked the back side of the fixture on the low pressure side of the valves.
