Moen Shower Handle Keeps Coming Loose Causes and Fixes

The problem is most likely a loosened screw inside the handle. It fails to retain the inner ring in place. And thus, the handle has a wiggly feel to it. Also, a worn-out cartridge can be a reason. Its stem can be damaged or slippery.

In this article, we’ve included and explained the various causes of the Moen shower handle coming loose and their fixes.

Moen Shower Handle Keeps Coming Loose Causes and Fixes

The most common cause of a defective shower handle is normal wear and tear. Remove the screw cover and tighten the handle screw if the shower handle gets loose. Keeping the screw tight can extend the life of a shower handle.

However, there can be other reasons for a faulty shower handle.

Possible Causes of a Moen Shower Handle Getting Loose

Loose Screw

There is an inner ring in the handle that keeps it in one place. With the help of a screw, the rings are held tight. These rings begin to rotate somewhat if the screw is loosened. To put it another way, the handles no longer feel sturdy. 

Instead, it begins to wiggle as a result of this.

Worn Cartridge

There are three parts in a cartridge body—ceramic discs, a bonnet nut, and a stem. The stem of the cartridge is attached to the handle. When you spin the handle, the stem rotates as well. So a worn cartridge can cause the handle to lose.

Stripped Screws

It is possible to experience wiggling as a result of stripped screws, although this is quite rare. It’s most likely a stripped screw underneath the handle that’s causing the problem. In this case, the screws must be completely replaced. And it is quite easy to remove stripped screws!

Ways to Fix a Shower Handle

Now that we know the causes of the problem, it’s time to fix the problem. It may require 5-10 minutes maximum.

To start the procedure, the following tools are required—

• Soft clothes
• Cartridge
• Grease
• Philip Screwdriver
• Flathead Screwdriver
• Crescent Wrench (optional)
• Hex Screwdriver (optional)

Turn off the Water Supply

Before attempting the repair, turn off the water supply first. Otherwise, the handle will immediately overflow the bathroom. You are not done yet. The supply line is still full of water. 

You have to turn on the handle to drain it completely. This also restores the overall pressure of the handle. After you are done, make sure to plug in the shower drain. Otherwise, you can lose screws or other equipment down the drain.

Detach the Handles

Now that the water is turned off, you have to remove the handles.

There is a screw in the middle of the Moen shower handle. It is sealed off by a plastic cap. After removing the cap, check the screw-type using a flashlight. These handles mostly use a hex screw. You will require a hex screwdriver in that case.

Wash the handle if it is dirty and stained. It will remove any filth both inside and out.

Tighten the Screw Inside

You will need to apply some grease inside the handle and around the stem. While you’re at it, have a look at the screw. Place the handle in its default position if the screws are perfect. After that, use a screwdriver to properly tighten the screws. 

The cartridge is also exposed when the handle is detached. Don’t forget to check while working on the handles. Examine the cartridge stems for any damage or scratches. If the item is damaged or worn out, replace the cartridge.

Reinstall the Handle

The only thing left to do now replaces the handle. Take the handle and firmly place it on the cartridge. Put the screw in. Tighten the handles with a proper screwdriver. Try out the handles to see if they’re up to the task. Turn on the water supply and look for leaks.

FAQ

What’s the perfect way to clean a Moen shower handle?

Use mild liquid dishwashing soap and a damp cloth to clean, then rinse and dry with a soft towel. Don’t clean with ammonia-based cleaners, sodium hypochlorite or bleach, alcohols, abrasives, or other harsh chemicals. Follow the manufacturer’s recommendations for cleaning. After using the cleaners, rinse them well with water.

Why is it so difficult to twist my Moen shower handle?

The most common reason for a Moen shower handle to twist is accumulation. Water-borne deposits, especially calcium, can build up over time and block the screw mechanism inside. Also, residues from toiletry and shower products can make twisting the handle difficult. Besides accumulation, broken rubber around the stem, or internal rust can also tighten the handle.

How to adjust a Moen shower?

First, adjust the temperature range and then the PosiTemp device. Minor modification to the water pressure is required if any foreign material clogs the line. Turn off the hot and cold water lines and remove the balancing pool. Shake it to get rid of any foreign particles.
