In response to Re: loud knocking noises when flushing toilets
: Hi there,

: I have a new bungalow with 2 bathrooms in it. whenever I flush either toilet after the bowl is clean I hear knocking noises coming from the stack. I have had the builder send their contractor out and he is trying to tell me that the noise is because of the plastic pipes and that's the sound they make. What I am wondering is if anyone else has had this problem and what the real reason may be so that I can go back to my builder to get this issue fixed.

: any help would be greatly appreciated.
: James; One possibility is a loose hanger on the vent pipe riser, or not enough hanger clamps. Also it could be the supply water line to the toilet not anchored securely. Keep after the builder,and he will keep after the plumber to correct. Hube
