place have had a lot of serious pin holing problems in copper pipe.

We turn off our water when we're away for any length of time but still
had our copper replaced with PVC after having one pinhole develop. The
plumbers around here do a lively business with PVC replacement and
they get to keep the copper as part of the deal. The theory du jour
is that the RO treatment plant changes the PH level of the water just
enough to make it corrosive. I never believed it until it happened to
us.

I had turned our water off when we went to the Shenandoah park. When I returned there
was another puddle on the basement floor. As it turns out, the main shutoff valve has
a leak in it. That leak allowed the pressure to build up and the pin hole to start
squirting again. The leak is slow, and the plumber says it's not worth replacing the
valve. The moral of the story is to shut off the valve but leave a low faucet on so
the pressure will not build if the valve leaks.

It took only 71 years for me to learn that.

Amazing.
