How to Replace a Delta Shower Cartridge

Replacing a delta shower valve cartridge is a fairly simple task that can be accomplished in just a few steps. Here is a detailed step-by-step guide with instructions on how to replace a delta shower valve cartridge :


Step by step shower cartridge replacement

  1. First, turn off the water supply to the shower valve. This is usually done by turning off the shut-off valves located under the sink or behind the toilet.
  2. Next, remove the handle of the shower valve. This is usually done by removing the handle screw or handle cap located at the top of the handle, and then pulling the handle off.
  3. Once the handle is removed, you should see a small cap or plug covering the cartridge. Remove this cap or plug using a flathead screwdriver or a cartridge removal tool.
  4. With the cap or plug removed, you should be able to see the cartridge inside the valve. Use a pair of pliers to gently pull the cartridge out of the valve.
  5. Take the new cartridge and align the notches or splines on the cartridge with the notches or splines on the valve. Insert the cartridge into the valve and use the pliers to gently push it into place.
  6. Once the cartridge is fully seated, replace the cap or plug and the handle of the shower valve.
  7. Finally, turn the water supply back on and test the shower to make sure the new cartridge is working properly.

It is important to note that different shower valves may have slightly different instructions for replacing the cartridge. If you are unsure about any of the steps, it is always best to consult the manufacturer’s instructions or a professional plumber.

how to adjust the temperature setting of the cartridge

To adjust the temperature setting of a delta shower valve cartridge, you will need to locate the temperature limit stop. This is a small screw or dial that controls the maximum temperature of the water.


  1. First, locate the temperature limit stop. This is usually located on the side of the cartridge or on the back of the valve.
  2. Using a flathead screwdriver or an Allen wrench (depending on the type of temperature limit stop), turn the screw or dial clockwise to increase the maximum temperature or counterclockwise to decrease the maximum temperature.
  3. Once you have adjusted the temperature limit stop to your desired setting, turn the water supply back on and test the shower to make sure the temperature is correct.

It is important to note that the temperature limit stop is designed to protect you from scalding hot water. It is always best to set the maximum temperature to a safe level, especially if you have young children or elderly family members who may be using the shower.
