How To Replace A Shower Cartridge [Step By Step Guide]

Surprisingly, it is really quick to repair different problems that suddenly pop up with your bath and shower cartridge. If you have trouble turning the faucets on or off or regulating the temperature, you will possibly need to fix or replace your faucet cartridge.

You will easily find whether your single-handle bathroom and shower hob cartridge is a form of the cartouche, ball, or disk when you turn off the water flow and go for the removal of handle and escutcheon.

Notice that the hard water and mineral deposits can be the reason behind the faucet issue before you go for shower cartridge replacement. So, instead of asking how to replace a shower cartridge, get ready to give a cursory look to this article.

If the depots are clear when the faucet is disassembled, use vinegar to soak the cartridge until it is reassembled. Otherwise, you would need to patch or replace a certain section with a faulty cartridge.

The cartridge manufacturers create different designs, so when you buy the parts of replacement, make sure it fits your cartridge. If the damage is severe, the whole cartridge will have to be replaced.

How Are Cartridge Valves?

Cartridge valves are one of four types of valves inside a roller holder and are especially suitable for shower rollers. A cartridge has holes that regulate flow and temperature when the handle is turned, and it provides a more accurate control than other types of ropes.

One of their benefits is that it is easy to recycle cartridges, as long as the effort does not impede mineral deposits and corrosion. Follow our below steps to find out how to move a tub or shower cartridge to ensure your bathroom equipment’s smooth running.

What Steps To Follow For Shower Cartridge Replacement

1. Cartridge Control Access

Whichever model of faucet you’ve got, the water source must be turned off before you disassemble or scalded it. Then you have to find out how to detach it up, and it is not always easy.

The cartridge lies just behind the handle, but the attachments that carry the handle are difficult to remove. Look for an Allen nut in an unnoticed position, such as below the lever, if there is no cap hiding a retaining screw. The rest of the attachment is simple once you locate and remove it.

2. Removing the Handle

Stop the water flow to the mount before you begin, and turn the faucet on until the water stops flowing. You can use a hex wrench to remove the handle. Remove the screws that hold the escutcheon and take it out.

3. Remove The Retaining Clip

If a chrome sleeve remains, detach or remove the chromium. To remove the retaining clip that aids in holding the cartridge in its place, use a small screwdriver.

3. Cartridge Removal

With pliers, some cartridges can be quickly removed. Others require a special pulling bracket for a particular brand of the faucet (usually available in hardware shops or home centers).

When the cartridge is tapered (which operates by its tapered form rather than by a number of grooves), remember the orientation of the cartridge when you remove it so that it can be placed back in the same direction.

When you re-install the cartridge, give a 180 degrees turn to it to make sure the fitting is tight.

4. Substitute O-Rings

Look for cartridge mineral deposits and, if possible, soak them in vinegar for cleaning. Adjust the O-rings and other worn parts as necessary if the cartridge has a good condition. Use a thin coat of silicone to clean the O-rings before reinstallation (it doesn’t cost any more to replenish the cartridge).

5. Fresh Cartridge Installation

Put the new or rebuilt cartouche in the body of the roller, as originally oriented. Slide through the clip and substitute the handle and fix it. If your shower cartridge has no anti-scald valve, a regular cartridge in an older valve can, in some cases, be replaced by a new anti-scald cartridge.

Due to its painful and hazardous scalding water, plumbing codes also need new shower rods that prohibit very hot water from flowing. Others have a thermostatic system that minimizes the flow of hot water when required, or an anti-scald moisturizer prevents cold water from turning off.

Check that your valve normally has an anti-scald valve. You can often hear a click by faucet signaling that the device has a valve to counter scald.

Things Do You Need To Complete Process


The way the valve cartridge is replaced can differ depending on which company made the valve. If you have a Moen valve, you should know that Moen makes replacement parts.

They can be found in most home and storage facilities. They sometimes have a cartridge removal method so that the substitute cartridge is obtained before the work is started.

Tools You Need:

  • Screwdriver
  • Shower Cartridge Puller
  • Caulk Gun
  • Flathead Screwdriver
  • Keep a Towel to keep the tools

A Quick Review

  • For the earliest model of a single-handle shower valve, these instructions are applied. Follow the instructions of the manufacturer for your valve style.
  • Begin with the removal of the shower handle. In general, there is a covering plate with a flathead screwdriver. Hold the handle close and shake off with the same screwdriver and loosen the screw behind the cover plate.
  • Remove the plate from the escutcheon by cutting it.
  • Look to see if there is a shower valve water shutdown. Otherwise, shut off the water from the primary water source.
  • The cartridge in the shower valve has a short clip. Pry that up carefully.
  • To work the old cartridge back and forth carefully, use a cartridge removal tool before it can be removed safely from the wall. With the replacement cardboard, the cartridge removal tool can be incorporated.
  • Using a pair of tongs to pull out of the wall carefully until the cartridge is free. Don’t force this out. If it is damaged during removal, the whole valve may be broken, and the whole thing needs to be replaced.
  • Put some grease on your substitute cartridge and stick to the valve carefully.
  • Please put the small clip in the new cartridge.
  • To achieve a waterproof seal, apply a silicone bead and a foam bead on the back of the scoop.
  • Screw back into place the cover plate and manage the tub.
  • Switch on the water supply.
