We’ve been hearing disturbing sounds that reverberate throughout our ground floor / kitchen for a few weeks now. It was tied to our powder room and happens whenever the toilet tank fills up.
In the beginning, I attributed it to inconsistent water pressure caused by repairs being made to a large/major water main break a few streets away. The husband, however, thought it had to do with the fill valve - I wasn’t convinced. Whenever it happens, we turn off the supply valve, the noise stops, and we turn it on again.
A couple of weeks later, I came across a set of reels in FB posted by a plumber content creator and got a name for what we have been experiencing, “water hammering”. And now that I have a name for it and have read / watched more posts, I realize it’s not a benign issue as it may cause joints inside walls to loosen up.
I gave husband the go signal and pushed him to order the replacement valve and we replaced it this weekend and we were able to replace it successfully, thanks to the internet.
It leaked a bit the first time we installed the new part but we redid it and pushed down slightly on the valve while we tightened the locknut underneath the tank. Teflon tape also helped prevent leaks.
So far so good.
