Richard Padgett has noticed that his water pipes rattle when a toilet flushes, and upon investigation it appears to be a pressure problem (water pressure too high in his house). FCWA (Fairfax County Water Authority) is coming tomorrow (Wed, 3/16) to test the water pressure at the street to house level.
If anyone is having similar issues and would like it reported to FCWA, please enter a comment to this post with your name and street address and Richard will report it to FCWA.
Meanwhile, Richard, keep your head above water. hahaha
