Whistling, Squealing faucet/pipe on 2nd Floor

[creative1000]

We have a pipe or shower faucet that whistles like crazy when it is off. After we open the faucet at max for 20 seconds and let a bunch of water out, the noise stops. This temporarily fixes the problem for a few hours / days /or weeks when the problem randomly comes back.

Just some preliminary google research says the noise is caused by a pocket of air as a result of a broken seal where the faucet connects?

Should I just remove the faucet, reseal it again with silicone tape, or silicone glue, and put the old faucet back on?

 

or should I replace the entire faucet too?  OR could there be a different solution to the problem?    Note: The faucet isn't leaky or damp, works 100% normal.

Funny you say that,  I had 2 taps where the flow was very poor,

gave them both a couple of taps with a hammer, and flow was

back to normal, did not see anything that came out ,that could

have been blocking them....

Had a similar issue about 6 months ago, also when the taps were closed.

 

Changed/replaced the seal on one of the faucets and that  fixed the noise.

It could be also an air inlet by a leakage somewhere else, the air coming slowly to the higher level.

In the days when the tap washer was a brass fitting, the pulmbers here would give the shank of the valve a hit with a hammer to slightly change the shape of the stem from round( and loose in the valve) to slightly eliptical (and tight fit in the valve).

Mainly though this was to stop squealing when on, not off.

Could work the same though.

Had same problem here. Replace the faucet, problem solved.
