Vibrating water lines - any idea?

It sounds like what you're experiencing is "water hammer". It occurs when there a sudden stop of the water. Try closing the faucets or valves slower. You should feel it if you turn off a fire hydrant too fast. It'll make the ground shake under your feet. Water mains have been broken due to the stress.

Hi,

Ok, so I finally got enough wall cut away to access the nuts and I got a wrench large enough to turn them. I loosened the nut ever so slightly and then retightened it a little more than it was, but it has a small drop leak forming every 15 to 20 seconds. I'm planning on swapping this out tomorrow - I'm going to take this regulator out and take it to Locke supply to get a replacement. Will I need to use some of that teflon tape on it or something?

Thanks,

Alan

Hi,

Thanks for all the good advice in this thread - I tackled this on Thursday and it wasn't too bad a job at all. I used a plastic bag to wrap around the pipe and redirect any spilled water forward of the wall and into a pail. Getting the old regulator out wasn't too bad and I took it over to locke supply and picked up a replacement. I had to push it a bit to get it into place, but once I did and tightened the rings real good, everything works great. It says it came preset at 70 psi instead of 50 though.

Glad everything worked out well for you. I haven't been on in a couple of days so I was wondering how your project turned out.
