Whistling noises in plumbing usually originate from flow restriction points. In the case below it is likely to be the faucet handle valve. A new valve washer may eliminate the noise.
I have not read if PEX tubing would transmit less noise, but being plastic it appears to me that it should dampen it. - Gil Laster, Charlotte, NC --- Original Message: Our kitchen sink makes this discordant whistle that doesn't bother me unless I'm eating. Can't hear it but 3-4 feet away from the sink, not farther. So, I was wondering, does copper flex, or the pex tubing make more or less sound than standard copper pipe?
