I recently discovered this newsgroup and have a question. I have two
upstairs bathrooms with a wall separating the two toilets (Kohler &
American Standard). The toilets sit back to back against the same
wall. This past summer one of the toilets(Kohler) start leaking at the
base. I had a plumber replace the wax ring beneath the base of the
leaky toilet. While doing so, he replaced the supply line which was a
gold metal one with a plastic supply line since he could not get the
alignment correct and needed the flex of the plastic supply line to make
Now the problem/noise.... ever since the repair, when the Kohler toilet
is filling up after a flush, a high pitch sound/squeal emits from the
pipes in the wall. If you go in the other bathroom, when flushing the
Kohler it is very loud. Actually you can hear it throughout the house.
The Kohler itself is not unusually loud when filling up, just the water
flowing in the pipes in the wall. When flushing the American Standard,
the noise is not that loud when in the other bathroom. Weird.....
