The dwelling is only 3 months old. 12 Dec 2002 at 11:58 pm #293399 Retired plbg1Participant High pressure and sometimes a bad washer. 13 Dec 2002 at 4:28 am #293400 plumbobParticipant I saw this just recently, it was a washer in a toilet ball cock. I was surprised. Turn the suplly off to a toilet and see if you hear it agian. 14 Dec 2002 at 4:01 am #293401 SelgasParticipant Yup I agree I have had the same problem with washers in ballcocks causing this noise – replacing them has fixed it.
