Whenever we use the showers in our house, there is always a loud noise, similar to the grinding "eeee" from construction sites. It doesn't matter if we use hot or cold water. Before, it was only happening in the main bathroom, now every bathrooms in the house have this noise. I was wondering if anyone know what the problem might be and how we can solve it?
Probably the easiest way to track down the source of the noise is to use a mechanic's stethoscope, which will cost you about $10 to $15 at any place that sells automotive repair tools.
Basically, a mechanic's stethoscope is similar to a doctor's stethoscope, but it has a metal probe on it. You put the stethoscope on your ears, and the closer the probe is touched to the source of the noise, the louder the noise will be heard through the stethoscope ear phones.
I've been a DIY'er for many years and for it's low cost, a mechanic's stethoscope is an excellent tool to have in your tool box for pinpointing the source of noises of all sorts, especially noises coming from machinery, such as electric appliances like washers, dryers, fridges and air conditioners.
This is what a mechanic's stethoscope looks like:
In fact, the stethoscope shown above is identical to the one I bought close to 20 years ago for $10 (or thereabouts) for locating the source of noises in my laundry machines. All you need is a cheap one costing less than $20, and it'll allow you to pinpoint the source of noises.
It's very possible that the source of the noise is a water supply pipe vibrating inside the wall. In that case, the noise will be heard loudest when the probe is touched to something connected directly to that pipe, such as the Tub & Shower faucet body.
I'd touch the metal probe to the shower head's too. It could be that the source of the noise is the flow restrictors in your shower heads vibrating. More likely, however, it's a pipe vibrating, and that means locating the pipe and anchoring it better than it's anchored now.This message has been edited. Last edited by: Nestor,
If your faucets are the type that have washers that meet with seats, then a likely cause of the noise is loose washers. Before taking any drastic measures, I'd replace the washers and make sure the screws are tight
pipes are loose and plumbing improperly installed no arrester tubes installed at faucets so when water is turned on they vibrate
