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 the connection.
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.....
Any ideas???
THANKS!!
