If your kitchen faucet tap is loose, fix it by tightening up the screw on the handle. It requires only the most basic skills and tools to complete this fast fix, which stops wobbly handles for good. If you have a screwdriver and know how to use it, this repair should only take about 10 minutes. No need to call a plumber or contractor --- just roll up your sleeves and get it done today.
Find the small screw located on the base of the tap handle. This is normally located right along the bottom of the handle in lever-style faucets, and on the very top of the handle in round or ball-shaped faucet handles. If there is a cap on your faucet handle, take it out first before your remove the screw.
Tighten the screw with an Allen wrench or a screwdriver --- whichever tool fits into the screw head --- until the handle is securely set on the stem of the cartridge. The stem is the part the handle rests on, and it is located under the handle.
Test the handle by operating it. If the handle is still loose, remove the screw and take off the handle by pulling it off the faucet. Slide on a new replacement handle and tighten the screw securely.
