Bought a new Clayton mobile home about 10 years ago. About 20 months ago I got a pinhole leak in the red Pex water line coming out of the water heater. 2 weeks later I got another hole about a foot from the first one. 6 months later I got a pinhole in the water line going to the fridge. It was not pex. After discovering another leak, this time under the floor my plumber checked the water pressure and it was 150. He said that was causing my pinhole leaks and replaced the pressure regulator. A year went by with no leaks and now I have had 2 leaks just in a week. Does anyone know why I I'm getting pinhole leaks? Did the 150 pressure weaken the pipes? I think im going to have to replace all the plumbing. Any suggestions? Thanks in advance!
