I have a cold line on one sink and a hot line in another sink. After
the water runs for a few seconds, the water "slams" off with a loud
bang. I can then keep the valve where it is (not turn it back to the
original off position) and turn it again in the on direction and it is
fine. The problem just happens from the initial off position to on.
They are old fixtures and one of them started after I tried to repair
a leak. I changed everything from the shutoff valve, flexible copper
tubing, the seat and valve. It does not appear to be house plumbing
problem as fixtures upstream and downstream work fine. Any clues?
Thanks.

buffalo ny: *"water hammer" *your water pressure may be high. on hot
and cold water, sometimes an air chamber device will be installed so
the rushing water thru the pipe hits the water hammer device to
cushion the shock noise. *other times, the dead end pipe stubs of the
hot and cold supplies are extended vertically above the stops off a
tee sometimes hidden in the wall, and the air inside can cushion the
noise. if those air chambers are waterlogged they won't work, *you can
completely drain the house and let the water out of them. *that's the
cheapest remedy. or you can buy or make inexpensive *"Water Hammer
Arrestor". *search this group for those terms.

I don't think this is a water hammer problem. There was no problem
for 10 years, then immediately after I "fixed it" (I actually did fix
the leak but now I have added this problem) it starts doing this?
Plus it's only on the cold side on one faucet? Weirder things have
happened but I barely even get a knocking sound when the washing
machine shuts off. The think the other poster might be onto something.

When I've had that sort of problem it's been with old fixtures that
use screwed on rubber valve seals. *The screw loosens and when you
first turn it on you get water, but then water gets behind the rubber
seal and forces it back down QUICKLY which makes the slam and shuts
off the water. *When you turn it even farther on you are taking the
slack out of the loose screw so it works ok then. *After you shut it
off you start the cycle over again.

That would explain why it happened immediately after fixing the leak.
The actual seats are metal threaded types (separate from the valve
body.) I doubt they came loose but maybe something within the valve
body (stem ???) I know on my shower they have screw on washers at the
bottom of the stem and maybe that is the culprit. At least I think
that's what you were referring to. I'll going to dismantle it
tonight. Thanks!

Hey I see that you flagged your message for deletion. Keep it, that
solved the problem for me and I am sure will help others in the
future. That was the trick, the washer on the bottom of the valve has
a screw through it that was loose. Problem solved! Thanks a ton!

I set that years ago. I'm not sure it matters anyway, I think Google

Not true. Google does not save those posts, and on more than one
occasion, I've been "short changed" while searching groups for a
answer/solution, because the answer/ solution was given, but the
person responding didn't quote the text.

I OFTEN search this and other groups before asking a question.

I've found answers/solutions dating back to 1994 in some cases.

Now we know where somebody got the idea for the piloted valve. (or may
have, anyway)
