My kitchen sink sprayer assembly is loose. In order to get it tightened properly, I need a very small basin wrench. All of the wrenches I have found are too large to fit into the tight spot where the nut is located. Where can I find a small basin wrench that has a head no larger than 1 inch across (outside measurement)?

Can try the ridgid plastic nut basin wrench... Click on the AOL link below:

Although your nut may not be a plastic nut that it fits.

Might also try a deep socket on an extension with a ratchet.

Otherwise, you could try holding the nut tight to the deck from underneath with a long rod and have a friend tighten the spray assembly by turning it clockwise.

Finally, you could also use an ADHESIVE CAULKING around the perimeter, clean it well and let it dry overnight... should hold pretty good for you.

Let me know what you think...

MARK

Just to clarify. Are talking about the trim piece that the spray handle fits into, or are you talking about the spray hose where it connects to the bottom of the facuet. If you are talking about where it connect to faucet, then you may be able to use a small pair of vise grips to tighten the nut. Doesn't have to be overly tight, just enough to not leak. Please correct me if I'm wrong or let me know if I'm right.

Thanks for the info. I will try these ideas

Both Mark and mygirlsda have given good advises if that wouldn't work for you, I will add my two cents, you can buy a crowfoot wrench to fit the nut open the link below, good luck
