Hi everyone. One of the showers in my house has a problem. When we are using it it starts making a loud-pitched squeling noise. I have already replaced the shower head with a new one, but that did not stop the noise. This is a tub/shower combo unit. I would like to attach a picture but I can't figure out how to do that on this forum (???). The unit is Moen brand, and may be 15 years old.

The diverter is on top of the tub spout. I do not have a shower wand or arm or anything like that. Just a simple showerhead and single hot/cold handle that does not pull out to adjust the amount flowing. Just on/off and temp adjustment. The noise does increase as the handle is turned increasingly hot or increasingly cold.

Any suggestions on what to do to stop this noise? It is driving us nuts.

Also, what is the "cleanout" on the tub body there for?

Thank you everyone for your time and help!!! I really appreciate it.

Thanks for the quick reply.

I had the same problem.
Found the filter/strainer on my Rinnai tank less heater partially blocked.
After cleaning the strainer the noise stopped.
Guess the lower water pressure some how created the sounds.

 

Can anyone give me any information on what might be causing my problem and how to solve it?

Thanks!

 

No expert, but perhaps the valve assembly itself is at fault? That wouldn't be such an easy fix though. Does the sound go away when you remove the shower head?

 

Thanks for the reply. So I switched out the cartridge earlier today and the sound is still there. No improvement. I also flushed out the pipes with no cartridge or shower head in place and not much junk came out into the water. Yes, the noise stops when I remove the showerhead or run the tub only. It is a single valve tub/shower unit with a diverter built into the spigot. (I should note that I already replaced the shower head and that didn't help either). My plan is to replace the spigot/diverter next and see if that does anything. It looks ok inside the spigot but I guess one of the O-ring seals could be worn or something.

Anybody have any ideas or suggestions? This is getting frustrating. Am I missing something here? Thanks!!
