Plumbing Question - Noisy Pipes/Water Hammer (houses, closing)

[Chase0909]

Hello,


Before I call a plumber and probably spend more than necessary, I figured this was an okay place to post my question. My house is 1925, been there 3 years, have all copper supply lines, and recently (probably about a month) I've noticed water hammer/hydraulic shock after flushing the toilet, running the sink and the valve closes, and when water is flowing into the washing machine. Being that a lot of people live in old houses with copper pipes, was wondering if anyone has any experience dealing with this personally and can suggest something. I would really appreciate it. I tried turning the main water supply off, left it 30 min for everything to drain out, and then turned it back on--but the noises came back. If anyone can relate, I would be very grateful-----like I said: been here 3 years, and I've never heard these noises until about a month ago. Where I think it's coming from is above the kitchen in the pipes leading up to the bathroom upstairs I am guessing. But the pipes aren't easily accessible, so.. I'm just guessing here.


Thank you

Offhand I would suggest searching the usual search engines such as ERGO (what I call Eeeeeevil Rrrracist Google) and also You Tube usually has lots of various video's on fixing things including plumbing.

When the OP finally decides to call a plumber, I hope that he does NOT call A.J. Perri:

Try shutting off the water supply again and turn on all the taps a little bit, flush all the toilets, etc. Then, with the taps still open a bit and the toilets and such ready to refill, turn back on the water supply. Give it a minute and start closing all the taps. Could be some air in the wrong place of the line. Often, though, the hammer is from somewhere in the walls where a support strap gas got loose and the pipe it flopping around when this or that shut off. For that, you would need to figure out exactly where the noise is coming from and tear open the wall to get at it.

I don't know what a water hammer is but I want one

I had an issue with vibrating pipes. I clamped them all to the beams at various locations and it went away.

No, you don't. It can result in a flood if it gets bad enough. Sometimes you can fix it by adding a water hammer arrester, but a lot of them are way too big.

water hammer has to do with water pressure, when I installed an auto timer on a front hose for the lawn, every time it shuts off, I would hear thunder, water hammering, it's very bad for the pipe if you don't fix it. I was able to installed a small extension, then the hammer was gone.

Usually it means the pressure is too high and when you shut if off all the sudden, it created water hammers.

I would definitely call a reputable plumber.. it's not worth saving some money to troubleshoot yourself.
