Another suggestion ?
I have exposed pipes as well. My camp is built into a side of a hill on stilts with the back section of the lower level exposed. Have always closed down the end of October and have never had a problem with broken pipes. As SAMIAM mentioned, it would take a few days of cold temperature to do some damage.
Just a thought though, could you use the "insulator" that can be put around the pipes. Does it work for cold as well as hot.
