Drain Noise

[AlmostDone]

I have three bathrooms. Two are upstairs, one is downstairs.

Over the last couple of months, I have been getting odd noises from the drains in the upstairs baths. They share a stack. The downstairs was treated as a branch. I have been getting a strange noise like a faint whistling or squeak noise. I can't say it occurs at any particular time. Sometimes I hear it right after turning off water, but sometimes I will hear it even though water has not been running or anything flushed for a while.

Thoughts?

Sometimes when a faucet is turned on partially a vibration will be created causing a whislte or singing of pipes. If the facet if opened further the singing shouild stop. Other than during rough in using rubber mountings frequently when passing through studs etc. I know of no other means to stop the singing. You might try a rubber mounting on the pipes under the faucet connections that you are hearing the singing. Sometimes this rubber mounting creating a tighter mount where it comes through the wall or flloor will eliviate the singing. Singing is normally due to cavitation of partially opened or resricted water flow.

Best I have maybe someone else will step in with a better answer.

Good Luck

Thanks once again for the response. Let me ask this. As I continue to hear this noise from time to time, I'm beginning to think it's coming from the toilets. Does that make any difference in your diagnosis?

I do not believe it changes anything in my thoughts. I did forget to mention that an anti surge valve installed in that area may help the sounds and cavitation involved.

Just a thought

I suspect the fill valve in one of the toilet to be the culpert

Go to each toilet and gently push the float down a very slight amount and see if you can get it to make a noise

If you have Fluidmaster fill valves, replace the diaphragm by turning off the water to the toilet, then rotate the top cap on the valve about 1/4 turn CCW and you'll see the daiphragm inside the cap

WG, being new to country living neighbor asked me if I know of any reasons why well pump may run to long in his estimation? apparently installed a new pump with brother in law and set pressure switch accordingly?? Also stated that pump will run some times without drawing water for anyreason.?? Had nothing to offer him? can a pump be to small? Could he be somehow loosing pressure from pressure tank, where water would(I have no idea how?)seep back into well causing pump to upstart againand again. I guess I either do not know what actually stops the water from draining back into well is their somesort of check valve to stop this?? He had asked me if bladder in pressure tank could be bad? know nothing about this either. Thanks Much
