I have a condo and for the last year off and on I get a banging sound in my pipes. The pipes bang for about 5 seconds, go away, then come back. This pattern can continue for a few hours. The noise can disappear for weeks then come back. Funny thing is there is no water in my unit running when the noise occurs. None of my toilets leak. Could this noise be coming from the unit below me or next to me?? Other people in the building hear the noise as well. Could it be air in the lines, pressure regulator or bad toilet?? thanks Pete
When building was built the plumber probably didnt make holes large enough for PVC pipe expands and con tracts and ma kes a noise. Also water lines could be making noise. People using fixtures above can make pipes noisy by you.
