You use that bathroom faucet numerous times a day, and it is quite obvious that the handles may get loose after some time. Furthermore, there are several other reasons why the handle loses grip, and using the faucet becomes challenging.

How to tighten a Moen bathroom faucet handle? To tighten the bathroom faucet handle, you need to tighten the screws that hold it with the main faucet body. First, use an Allen wrench to hold the faucet’s base, and then use a flathead screwdriver to fix the screws.

How To Tighten Moen Bathroom Faucet Handle

However, there may be some other issues why the handle has got loose and that I’ve discussed in this article. Read on to know how to tighten the bathroom faucet handle quickly and make it work as a new unit.

Types of Moen Bathroom Faucets

Moen offers a wide range of amazing bathroom faucets available in different sizes, shapes, and designs. The reason why I’ve listed the types here is that tightening the handle can vary depending on the faucet type you have.

Here are the common Moen bathroom faucet types that homeowners prefer:

1. Double-handle Faucets

The double-handle faucets, including the centerset ones, have a two-handle design, and the entire faucet has a single body unit. Tightening the handle for these faucets is easy, and all you need is a wrench and a flathead screwdriver.

One of the best selling double handle bathroom faucets from Moen is Moen 6410 Eva.

2. Single-handle Faucet

The single-handle faucets are the easiest to fix. These faucets can have a handle on the side or above the spout. There are some Moen bathroom faucets with a spring-loaded handle, and tightening it can be a little challenging.

One of the best selling single handle bathroom faucets from Moen is Moen Sarona Mediterranean.

3. Faucets with Hidden Screws

Faucets with hidden screws are available in both single and double handle options. However, the screws aren’t visible on the top, so you need to remove the main plate first.

Reasons why the Moen Bathroom Faucet Handle Gets Loose

Before I go ahead and explain the possible fixes, it is important to understand the reasons why the handles get loose. The most common reason is age, as you use the faucet multiple times every day, the handle loses its grip on the main body.

Below I’ve listed some other common reasons you need to know about.

1. Stripped Screws

This is a very rare issue but may happen if you rotate the handles with immense force. The faucet’s handle gets wiggly due to the stripped screws, and the handle may also come off sometimes.

Fixing this issue requires a slightly different approach than just tightening a loose handle. You need to replace the screws since the handle will not fit properly on the stripped screw head.

2. Loose Screws

The screws get loose over time, and this is a common issue most homeowners face. Every Moen faucet, be it a single handle or double handle, has inner rings that keep the handle secure. And screws are used to keep these rings packed in place.

If the screw gets loose due to regular use of the faucet, it leaves the ring, and as a result, the handle also gets loose. You’ll see that the handle starts wiggling while rotating, but it won’t come off easily.

3. Corroded Valve Seats

The valve seats aren’t directly connected to the handle, but they accommodate on the washers, which, when worn out, results in leaks. These leaks can lead to damaging the cartridge, which then causes the handle to get loose.

4. Damaged Cartridge

Every cartridge used in Moen bathroom faucets comprises three parts, i.e., the stem, ceramic discs, and bonnet nut. The stem holds the handle with the faucet’s body. If the cartridge wears out over time, it will result in the handle getting loose.

Steps to Tighten a Moen Bathroom Faucet Handle

Tightening a Moen bathroom faucet handle is a simple task, and you can do it within minutes. Below I have mentioned the complete process in detail, with the things you need to fix the loose handle.

Step 1: Gather All Necessary Tools and Items

  • Philips or Hex Screwdriver
  • Allen Wrench
  • Grease or WD40
  • Cartridges
  • Flathead Screwdriver
  • Soft Clothes

Step 2: Turn Off the Water Supply

If you don’t want to end up getting completely wet with water splashes, it would be great to turn off the water supply. Also, rotate the faucet handle gently to flush the leftover water inside the supply lines.

Make sure to plug the sink hole before fixing the handle, as small screws may fall off inside the drain, and it can be a big problem.

Step 3: Remove the Handle

To fix the loose handle, you need to remove it, and the process may vary depending on the type of Moen bathroom faucet you have. For single-handle faucets, you will find the screw in the middle.

There is a plastic cap that secures the screws, remove it using a flathead screwdriver, and then you can access the screws. Moen single-handle faucets usually have hex screws.

On the other hand, for double-handle or widespread faucets, you don’t need to worry about removing any plastic cap. These faucets have two handles, and the screws are under each handle. Turn the handle clockwise, and you can remove it easily.

Step 4: Tighten the Screws

Put the screwdriver on the screws, and check if they are loose. You might need a flashlight since the screws are small and may not be visible without enough illumination.

Tighten the screws using the screwdriver, and then check if it has fixed the loose handle. If the screws don’t move, apply WD40 or some other grease to make the screw rotate properly. To tighten a Moen double-handle bathroom faucet, you need to install the handles back to check if the issue has been resolved.

If the handles still move or wiggle a lot, there is something wrong with the cartridge. Move to step 4, and know how to fix a worn-out cartridge.

Step 5: Clean the Cartridge or Replace It

Sometimes the issue can be fixed by cleaning the Moen bathroom faucet cartridge. You will find the cartridge after removing the handle. Unscrew the screws, and you can easily remove the cartridge. Inspect it, and look for any signs of damage.

If everything looks fine, sediments may have caused the issue. Rinse the cartridge and install it back. Or you can replace the cartridge if there are any signs of damage on the O-rings or other parts of the faucet, such as the stem or the ceramic discs.

Put the cartridge in place, and use screws to secure it properly. Tighten the screws using a hex screwdriver, and you are good to go.

Step 6: Reinstall the Handle and Clean Up

Now you can install the handle back. For widespread or double-handle faucets, put the handle over the cartridge, and rotate it anticlockwise. Make sure to align the handle properly so that it sets into the threads and locks in place.

Lastly, clean the entire faucet using a soft cloth, and you can start using it again.
