Working in the kitchen with a wobbly kitchen faucet can be really annoying and burdensome.
And even after tightening the faucet, they can come loose again. “So why does my kitchen faucet keep coming loose?” you may be asking. Here are the reasons;

  • Loose screws: The kitchen faucet base and head are held in place by a bolt that’s under the sink. When the nuts that secure the bolt come loose, the faucet will become wobbly. This is as a result of the threads of the nuts becoming damaged.
  • Loose faucet base: Due to excessive use, the faucet handles that are attached to the base could loosen up. And this can result in a loose base, wobbly kitchen tap, and leaks. A loose base can also cause the water lines to rupture.
  • Worn-out O-rings: The O-rings secures the kitchen faucet handles in their right position. After extended usage, the O-rings can wear out and become loose. This will also result in a wobbly kitchen tap.

And if you have stained kitchen cabinets, then add protective layer on the outside as well as you don't want to get the stain or cabinet door damaged.

Step 3: Slide under the sink and find the nut

Now slide into the empty sink cabinet on your back, and turn your flashlight on.
Then locate the bolt on the roof of the cabinet. The position of the bolt should be directly under the kitchen faucet base. This is the nut that you will tighten.

Step 6: Check that the faucet base is tight

When you’re done tightening the bolt, come out from under the sink to check if the kitchen faucet is tight or it still moves around.

Tools you’ll need to DIY a loose kitchen faucet handle

  • Flathead screwdriver or knife
  • Flashlight
  • Hex head wrench (Allen wrench or key)

Steps to Easily Tighten Kitchen Faucet Handle

Step 1: Empty everything in the sink cabinet

First things first: remove all the items in the sink cabinet so you can embark on the work.

Step 2: Turn off the water supply valves

To avoid soaking yourself with water should anything break or go wrong, turn off the water supply valves.
This will also prevent water from gushing out when you turn the kitchen faucet on. So as a safety precaution, always turn the water valves off.

Step 3: Identify the kind of faucet you have

Some kitchen faucets are secured with a hex head screw: many others are secured with a Philips head screw.
But if you can’t find the screw head, you’ll have to take out the decorative cap in the handle to discover the kind of screw you have.
To remove the decorative cap in the handle, you’ll have to slide the edge of your flathead screwdriver or knife under the cap and pop it open.

Step 4: Tighten the screw

The way you’ll tighten the screw depends on the type of screw in your faucet handle.
If the set screw is located at the base of the handle, use your hex head wrench (Allen wrench) to tighten it by turning it clockwise.
And if the set screw is underneath a decorative cover, use your hex wrench or Philips head screwdriver to tighten the kitchen faucet handle accordingly. Hold the faucet handle in position and screw in a clockwise manner.
Caveat: the reason we closed the water supply valves before we began to work is that, when using a hex wrench, you might need to turn on your faucet handle.

  • Allen key or hex head wrench
  • Rubber seals
  • Screwdriver
  • Pipe wrench
  • Old toothbrush
  • New O-ring
  • Heatproof silicone plumber’s grease

Now, these are the steps to tighten a single handle kitchen faucet at home.

Screws are mostly used to attach the handles of faucets to the faucet cartridge. And sometimes, a decorative cap is used to hide the screw.
Remove the cap and unscrew with a hex head wrench or an Allen wrench. Then gently take out the kitchen faucet handle.

Once you’re done cleaning and replacing the damaged parts, reassemble the faucet and tighten the screws.
