When the washing machine is running and I imagine drawing water the nearby kitchen faucet makes a humming noise. Noise can also be heard in bathroom it seems from shower faucet.

Same apt and when shower is turn on at high rate the humming starts at the shower faucet. Simultaneously the kitchen faucet will turn on.

I'm not a plumber. This started I'm the last two weeks in a high rise residential building where there has been some maintenance outside the unit where this is occuring.

This issue does not seem to occur at the bathroom sink faucet which is fairly new having been replaced approximately two years ago. The other plumbing I think is at least 20 years old. The water heater is tankless and located in the bathroom.

If there are any other details you need let me know. I don't know if the main valve is inside the apartment unit. My first thought is it needs adjustment to lower pressure for some reason but the question is why now? Again I'm not close to being a plumber.

 

'When the washing machine is running and I imagine drawing water the nearby kitchen faucet makes a humming noise." What happens when you don't imagine?

 

imagine was a poor choice of words. What I meant is when the washing machine is running and it calls for water to enter the machine.

If you are qualified to help because you know something about plumbing then help. Otherwise take it to the BS thread.

 

Those are your words not mine. Difficult to provide help when the problem is not clearly described. I would be a little more humble when looking for help but you seem smart enough to fix it yourself.

 

Reading the grammar and wording of your post asking for help doesn't leave you much room to call others on BS.

"...when shower is turn on at high rate the humming starts at the shower faucet. Simultaneously the kitchen faucet will turn on." I'd say you have poltergeist judging by the mischievous behavior.

 

It's called water hammer and related to pressure regulation. You are right, I don't need assistance on this -- based on the type of assistance I desire. It's too technical and better handeled by a professional plumber. Aight!

 

Yes, for you I think hiring a professional would be a good idea.
