Hi,

Anybody have any ideas for me on this problem? I've never encountered it
before. If I turn on a sink facuet or bathrub facuet, let it run for a
little bit, and then shut it off, the toilet will run for a little bit and
then stop.

Ever heard of this? What causes it? My only thought is that perhaps the
filler valve is week and the "water hammer" effect of the momentum of the
water suddenly shut off at the sink is causing the pressure to trip the
water valve momentarily.
