| Hi Thanks for the quick reply, and sorry for the missed information. Its an American Standard over 20 years old and the noise appears to come from the toilet bowl proper as the water goes through the pipe at the bottom of the water storage unit on top of the lavatory bowl, I believe its called a cistern, into the bowl. I was thinking they may make some sound abrorbing material that one could put onto the lavatory seat cover, as its down when the toilet is flushed. Thanks again for your help |
