Whistling sound form pipes in apartment builiding
Posted by James Kulczycki on February 15, 1999 at 09:03:51:
Although I've read many posts in this forum on a similar theme, none quite address my situation. It's a 35 year
old, 26-floor apartment building. Whenever one of my neighbours (up, down, beside? I don't know) turns on
their water, a very, very loud whistling sound comes from within the wall immediately behind my kitchen sink.
Turning on the water in my apartment makes no difference, nor does turning off the shut-off valves under the
sink. I don't think it is from shower or toilet use due to the random duration of the noise: from a second to
many, many minutes. The sound has gotten louder over time and it is now so loud that it is putting me over the
edge. Of course, the building management is uninterested in helping. One clue as to the cause is that just
before this started six months ago, every toilet, showerhead, and faucet aerator in the building was replaced
with low-flow devices. My amateur assessment is that the low-flow devices are causing a buildup of pressure
(which is quite good) which is somehow casuing this noise. Any ideas out there? My next step is to visit my
neighbours one by one and hopefully they will let me turn on their taps to find out which apartment is causing
this. If I find its more than one, I don't know what I'll do. Please help!
