Follow up.... I tried the manual movement of the switch and it still
made the water hammer noise. It feels like on the switch that there's
no slow transition between on and off, it suddenly shuts the water.
Just to be sure..... the noise I hear comes from 1 location in the
basement, it's of the water pipe rubbing against the joist for the
floor (sounds like a rattling/rubbing noise as the pipe shakes for a
second or two). Is there a new ballock I can buy that closes slowly
(do they wear out and now mine closes suddenly or something). I hate
to put too much time/money into this if its only caused by the toilet.
Why would it suddenly start up?


Have you considered simply trying to restrain the pipe so it doesn't
vibrate like that, it should be pretty easy to "tie it down" or jam
something soft between it and what it rattles against.

I've got a feeling that most new fill valves will "snap" closed. The
ancient "ballcock" valves just squeezed the water off more and more as
the float rose, but sometimes would "squeal" for a few seconds just
before they fully closed.
