I'm trying to dull the tapping noise from the pipes in my ceiling.
What materials could I use to deaden the noise? I tried cork tiles
but that had no effect whatsoever on the noise.
I've read that the idea is to use many layers of different materials.
If (and it's a big IF) the pipe noise is due to the need for a pressure
regulator, you MIGHT find it's cheaper to have a plumber install one,
compared to your soundproofing idea. Did you landlord have a plumber take a
look at the situation? Is there a regulator in place? They generally look
like this one:
If you insist on pursuing the soundproofing idea, you may as well do it
right, with products like this:
A regulator wouldn't cause noise. It's a thing that decreases the water
pressure coming in from the supply pipes, bringing it down to a level which
some believe is safer for appliances. I can also eliminate noisy pipes
The noise might be intermittent because the water pressure for the whole
system can vary depending on time of day and how many others are using water
in the building.
Ask everyone you know if they have a plumber they like. Call one of the
plumbers. Some will stop by for free to check out the situation. Be clear
with him on the phone, explaining that it's not your building, and the only
work you're allowed to do might be a regulator or some other thing that
doesn't involve ripping our walls & ceilings. And of course, be sure your
landlord will actually let you pay for the installation of a regulator
before you waste the plumber's time with a visit that will never make him
A regulator for my house costs around $60 at a plumbing supply place. I was
quoted $50 to install it. Nobody but the plumber can tell you the labor rate
for your situation, or if your building might need a regulator whose price
is different from mine.
Pipes are held in place by U-shaped hangers nailed to the beams. Modern ones
may be plastic, but older ones are metal. Metal corrodes. The pipe might be
moving back & forth slightly and making noise as it rubs against the
This doesn't matter, though, because it's not your building, so you can't
open up the walls or ceilings to fix the problem. Have you checked yet to
see if there's a pressure regulator? I supplied you with a picture of one so
you can identify the thing.
A slight tapping noise is not imo likely to be rubbing per se but more
likely thermal contraction/expansion--very similar to the occasional
pop/creak heard in a house's siding when warms up in sun on a cold day.
I had one house w/ a very long horizontal drain run from a sink -- in
it, there was a sound that could be described as a tap that was actually
a drip internally until that drain line finally finished emptying.
It would be a pressure-reducing valve and is a spring-loaded valve that
could be installed to reduce house pressure from the higher-pressure
distribution system. Normally, if these get noisy they make a more
distinct sound than I would describe as a tap, but I suppose if it were
buried in a wall or a ceiling somewhere it could be muffled.

Heating season, perhaps? Apartment (wood) drying out? Were you
there last year at this time? It's kinda hard to troubleshoot
these sorts of things over the Internet. If your super says they
won't fix it there isn't much you can do about it, except ignore it
Sometimes it's not? Well, sometimes you have the condition that
causes the tapping and sometimes not. Sometimes in one place,
sometimes in the other...
A pressure regulator may stop some pipe noise (banging, primarily),
not cause it.
