More pinholes
Posted by Steve Spector on October 12, 19100 at 19:35:56:
My area in Montgomery County, MD has had an epidemic of pinholes since our water authority replaced the water mains and flushed some chemical into the system. Our plumber mentioned a pressure regulator as an alternative to replacing the pipes. We are in a ranch house with no basement. The pipes enter by the kitchen, then cross the house in the attic.
The idea is the corrosive gunk and the high pressure combine to drill into weak parts of the pipe to form the pinholes.
A pressure regulator would reduce the process.
Does this make sense?
