Squealing shower?

Question

I just moved into my new house, and had replaced the shower head, as the old one was not working. The flow/pressure was very low - when the diverter on the faucet was pulled, most of the water still came out of the faucet, rather than the shower. So, I replaced the faucet with a brand new one with diverter. The shower now works great, but it makes a loud squealing/whistling noise. How can I fix this? There does seem to be a small gap between the new faucet and the shower wall; could that be the problem, and if so, how can I fix it?

Answer 1

I had a similar, intermittent problem at my old house.  I found that once the noise started, if I pushed the diverter plunger down just slightly, it would stop the noise.  A few drips of water or a small stream might come from the faucet after doing so, but not enough to affect the shower head pressure.  Of course it's not a permanent solution, but on the rare occasion the noise occurred, this did the trick for me.

I doubt the small gap between the faucet and shower wall has anything to do with it.  However, it might be a good idea to seal that gap with some caulk so water doesn't enter your wall cavity.
