A few weeks ago my kitchen faucet started dripping, no big deal change the valve seat and spring; leak fixed. Then the bath-tub, same problem, same repair. Then the bathroom sink...same deal. Then the toilet valve...removed & new one installed.
Common finding was that none of the parts removed & replaced seemed worn or defective.
Yesterday, I noticed a puddle of water atop the water heater at the inlet connection, pulled of insulation and found some serious corrosion between copper fitting and tank (a separate problem) but a new leak also.

Last night, the bath tub faucet started dripping intermittently again.

I'm starting to suspect that we're getting high water pressure surges that are enough to bypass the valve seat seals & springs. Going to put a pressure gauge on system today to check.

Anybody experience this type of problem? Thanks.
