Noisy new faucet and older tub faucet
We just changed out a pedestal sink to a vessel sink. Bought a new faucet. All the plumbing was hooked up to what was there in the wall. Just new faucet, all new plumbing hooking up to the pipes in the wall. Now, whenever we turn on the water, it is very noisy. No banging or anything like that. Just a lot of noise, as though there is a lot of air going through with the water.
Our house is almost 11 years old. The faucet to one of the bathtubs has always been horrifically noisy for the tub - so much that we can hear it, loudly, upstairs. When the shower diverter is on, it is much less noisy. No banging in the wall. Just lots of noise, very similar (but much louder) than the new faucet.
Any suggestions as to what is causing this and what can be done to lessen the noise? The new faucet is in the powder room and the tub is in the guest room bath - so guests get an earful whenever they come to visit.
