How to Repair a Loose Single Handle on the Kitchen Sink Faucet

It is frustrating to find yourself fighting with a loose kitchen faucet handle while trying to wash dishes. Repairing a single handle on a kitchen faucet is relatively easy depending on the faucet type. Some faucets have a small visible Allen screw close to the handle that attaches the handle to the base. Other faucet types have a cap on top of the faucet that you must remove first before you see a Phillips screw that attaches the handle to the base. Take a look at your faucet to determine what kind of faucet you have.

Remove a Faucet Handle

Step 1

Open the cabinet underneath the sink, and use the shut-off valves to turn off the hot and cold water.

Step 2

Turn on the single handle faucet to release pressure in the water line.

Step 3

Put some rags over the drain holes of both sides of the sink to prevent losing any parts.

Step 4

Remove the screw that attaches the faucet handle to its base. If your faucet has a visible Allen screw close to the handle, use an Allen wrench to carefully remove the screw. If your faucet has a cap covering the Phillips screw, pry the lid off with the standard screwdriver, then use the Phillips screwdriver to remove the screw.

Step 5

Wipe the inside of the handle body and stem with a rag to clean any built-up debris.
