I am entertaining the thought of installing one of the rain-type shower heads in a second floor bathroom. I am trying to figure out if this is a good idea, due to the fact that the house is USDA Zone 5, with winters temps that can get below zero. My thinking is that as long as I install the water line with a little bit of pitch, the water should drain out of the line through the shower head and not freeze in the pipe.
Is my thinking correct?
Are there any other "gotchas" I should be aware of?
