As I mentioned in an earlier post I plan on having my water shut off for a few months with the furnace on during some renovations. Now I have been thinking about the possibility of some detrimental effects to my copper piping by doing this. Is this a possibility or am I over stressing this? I suppose I could hire someone to come assist me with blowing out the pipes? I am not very familiar with plumbing and have been concerned with all the grey areas.
