I have a 3 level Townhouse house built in '78 and we have been doing work on it so we have had the water off. Yesterday when the water was turned back on the whole house got a bath, water went everywhere I had it turned off and called a relitive to help(He and his father both do Gen contracting and plumbing) after tearing up the ceiling under the two upper baths we found that the leak was a broken connection behide the tub and maybe another leak in the bathroom on the main floor. This plummer wants me to change out every pipe in the house from copper to PVC and start New just incase another leak show up. Does this sound right to anyone else it doesn't to me????
