My wife was walking in the kitchen barefoot and noticed around one wall the tile was warm. Then she went into the adjoining bathroom and the tile in there was also warm, both in an area about 3 feet square. Water and light bills were only $10~$15 more than last month. The house was built in 1978 with copper plumbing throughout. I'm thinking we have. a small leak in the hot water line feeding the bathroom. I've called a foundation repair company (Olshan's) and they're coming on June 1st to check it out.
Was wondering if any of y'all have had a similar problem and what it took to fix it. Not looking forward to jack hammering the floor in the house, but don't know of other options. There are 90* elbows on some of the exposed piping I've seen in the house, so I don't think sleeving is possible.
TIA,
