In response to Re: More pinholes
: 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?

You need to Balance your pH. I try to maintain mine to 7.0. I use a chemical injector pump metering from a tank filled with a solution of light soda ash. The water coming from my well is acidic and pinholes develop rapidly around my well pump. To use this method you need a holding take with separate intake (middle of tank) and bottom of tank drawdown.
