I noticed under my kitchen sink water was leaking from my sprayer. I also noticed a noise that sound like air pulsating into the sprayer. I noticed that every time it pulsated the sprayer would leak. How do I stop the pulsating air into the sprayer?:confused:

Does this happen at a fast interval or is it rather slow.

There is a valve inside your faucet that controls the spray head, this deteriorate or wear out or sometimes get junk around them and they cease to function properly, you will have to take the faucet apart to get to this valve.

Are you saying the sprayer leaks where the hose connects to the valve body?
If so you have two problems. Is the leak in the hose itself or in the connection where the hose screws into the valve body?
The pulsating could be caused by some crud under the diverter, (see images.)
Remove vthe spout and check and clean the diverter. Reassemble and test. Let me know how you make out, Good luck, Tom
