Kitchen faucet hose making noise

Hello, I have a hose attached to my kitchen sink. Every time it is turned on it makes noise that sounds like a hammer. The hot and cold faucets don't make noise and are working fine. The valves are on all the way for the hot and cold. Can someone please help? Thank you.

Has it always done this? How is your water pressure -- both out of the faucet and out of the sprayer? Have you experimented and tried turning the under-sink valves down a bit (in case your pressure is too high)?

This is the side sprayer hose, correct, not a garden hose attached to the faucet spout?

Spray hoses commonly make that thump sound when you release the trigger, it's the sudden stop of water within the faucet that is clunking. The fact that there is no noise with use of the faucet says that the issue is within the sprayer system. IMHO, it's nothing to worry about, but you can replace the valve within the faucet that controls the spray hose. Probably not worth the time or expense though, especially if you have to hire it done, it will be easier and cheaper to change the valve. My plumber just gave me an estimate on a kitchen faucet replacement at $185 to $225, depending on the style of faucet and conditions, faucet not included.

I would be cautious about turning the anglestops down, because most anglestops don't take well to being turned without leaking, and if they're cheap enough and old enough, the stem will snap off in your hand and you'll have a geyser under your sink. This actually happened to me last year when remodeling a bathroom, I expected it, though, and was prepared for it. I had demoed the old tile counter and left the sinks intact weeks before, until the new top was delivered AND the plumber was there.

At any rate, it is not wise to play with anglestops, unless you are certain that they will not break in your hand or leak afterward. If you replace an anglestop, be sure to use a ball valve style, they're a little more expensive, but they will NEVER leak, no matter where you adjust them, and they will always turn off 100%. Best way to go. 8-)

Yeah with multi-turn plunger-style supply valves, one must exercise them twice a year or so just to break away the mineral buildup. Just turn them all the way off and back on again.

Yikes, $225 is pretty expensive to replace a faucet. If that's a three hour job that is $75 an hour, but then again that is what you pay for automotive repair labor too I guess.

The hardest part of faucet replacement, of course, is the loosening and tightening of those lock washers from under the sink. Very awkward to work under there.

I got a white enamel cast iron sink in my kitchen. Never again. Stainless steel all the way from now on--it is so much more practical.

Cast iron sinks are quieter- especially with faucet-sprayers. I like them for top-mount only, and only on solid truly flat countertops. Otherwise I'm a stainless guy too ;)

@ the OP, a single 'thunk" when starting or stopping the sprayer isn't unusual but if it's sounding like a machine-gun the diverter mechanism in the faucet has gone bad. That usually means a new faucet as almost all of those are non-repairable.
