Friend's house is 6 years old. For the past 2+ years he has had to replace the plumbing around the hot water heater as well has continuous pin hole leaks that keep popping up in a +/-20 stick of pipe in the attack that winds around the AC unit and feeds the upstairs bathroom as well as their master bath. He has had either 7 or 8 pin hole leaks in this pipe in the attack. He has had plumbers and electricians come out to the house to look at it and at one time we thought it was because the plumbing wasn’t grounded because they got a really high amp reading. He had another guy come out and did the same thing and nothing, no amps were detected at all. Currently they only turn the water on in the house when they are cooking or bathing, other than that the water is turned off because they just can’t trust it. His master bedroom and bath are missing sheetrock and carpet sections from the last repair a few months ago and he doesn’t want to spend the money to fix it because another leak will happen and he will have to tear it out again.
