Tapping noise in wall after flushing upstairs toilets


We have two toilets upstairs. After flushing either toilet we hear a tapping noise in the walls on the main level of the house. The noise is a rapid tapping and tailors off within five or so seconds. We are trying to figure out the cause of this problem. Could this be a broken pipe strap? Should we be concerned that the pipes could separate?

Tapping noise in wall after flushing upstairs toilets


A couple things come to mind. Since the toilet water is cold, the pipe (especially PVC) could be contracting as a reaction to the addition of the cold temperature. May just be the pipe scraping against a stud or a hanger/clamp. May also be water dripping down the pipe and hitting a fitting in the lower living area. Since it goes away so quickly, this would be my guess.

Tapping noise in wall after flushing upstairs toilets


it could also be somthing wrong with the shut-off switch were directing water to the toilet.... it happened to me before when I need to change the shut-off switch for a sink to get rid of a big noise.... however, it happens to me with the hot water supply switch though.... not sure if cold water switch will be the same...
