No More Shaky Handles! How to Easily Tighten a Loose Moen Kitchen Faucet
Having a loose Moen kitchen faucet handle that shakes and wiggles when you turn it on and off can be incredibly annoying. Fortunately, a loose Moen faucet is usually an easy fix. With a few tools and simple steps, you can tighten a loose single-handle or two-handle Moen yourself in no time.
We'll also provide tips to help prevent the problem from reoccuring.
Reasons for a Loose Moen Kitchen Faucet Handle
There are a few key reasons why you may have a loose or wiggly handle on your Moen kitchen faucet:
Worn Out Internal Parts
The frequent twisting and turning of the handle can loosen internal parts over time. The cartridge nut that holds the handle onto the cartridge can become loose. Or the cartridge itself can become so worn down that it causes the wiggle. Deterioration of the stem attached to the handle is another common culprit.
Loose Retaining Screws
On a single-handle Moen faucet, there is usually a cap or bonnet that you have to unscrew to access the cartridge. The screws that hold this cap in place can slowly loosen up from repeated use. On a two-handle faucet, set screws hold the handles in place. These hex screws can also rattle loose and lead to a wiggly handle.
Deteriorated O-Rings
The O-rings inside a Moen faucet handle provide watertight seals to prevent leaks. Over time, these rubber gaskets wear out. When O-rings become cracked or flattened, water can seep through and cause both leaks and handle wiggle.
How to Tighten a Loose Single-Handle Moen Kitchen Faucet
Supplies Needed
- Adjustable wrench
- Socket wrench
- Replacement cartridge, stem, or O-rings (if needed)
Steps to Tighten
Here are the steps to tighten a loose single-handle Moen kitchen faucet:
- Turn off hot and cold water supply lines under sink.
- Pry off the handle with a flat head screwdriver.
- Use an adjustable wrench to unscrew the cap covering the cartridge.
- Grab a socket wrench to tighten the nut holding the cartridge in place.
- If handle is still loose, replace the cartridge with a new one.
- Replace the handle and turn water back on to test.
Tightening a Loose Two-Handle Moen Faucet
Locate Set Screws
On a two-handle Moen faucet, you'll need to find the set screws. Check the underside of each handle. The hex screwheads will either be on the sides or on the bottom.
Tighten Screws
Use an Allen wrench to tighten the set screws in a clockwise direction. Give them a few turns until nice and snug. Turn the water on to check if the handles are still loose.
Still Loose? Replace Stem
If tightening the set screws fails to stop the wiggle, the internal stem is likely damaged. Removing both handles and unscrewing the stems with a wrench allows you to inspect them and replace if needed. Reinstall new stems and handles to complete the repair.
Fixing a Loose Pull-Out Sprayer Faucet
For a loose handle on a pull-out sprayer style Moen faucet, start by using an adjustable wrench to tighten the set screw located just below the front of the handle. If it still feels loose, pry off the handle and tighten the cartridge nut underneath it with a wrench.
Prevent Loose Moen Kitchen Faucet Handles
To help avoid loose handle issues in the future:
- Periodically check screws and tighten as needed
- Replace old O-rings with new rubber gaskets
- Consider installing metal handle adapter kits for added durability
