Its is leaking where the sprayer attaches
Underneath the kitchen sink. It is real tight
But still leaks.Wish I wish I could close it off. Do
Not use the sprayer anyway. See attachment

Hi Oneill...

Looking at that I believe you can remove the spray hose connection at the faucet and then pick up a 3/8" and a 1/4" brass cap and teflon tape at home depot and cap the faucet.

If that fails to fix the leak then the leak is up in the faucet itself and you will need to purchase a new faucet.

Questions? Let me know, OK?

PS: Bring the old spray hose with you to home depot so you can confirm the thread size and the size of the brass cap you need and that way only purchase the brass cap you need.
