7 Steps on How to Identify Delta Shower Faucet Cartridge Model
Step 1: Gather Necessary Tools:
Before starting the process of identifying your Delta shower faucet cartridge model, make sure you have the following tools on hand:

Adjustable Wrench:
You will need an adjustable wrench to loosen and tighten the cartridge.
Screwdriver:
A screwdriver is needed to remove any screws holding the faucet handle or trim plate in place.
Pliers:
Pliers can be useful for removing any small parts, such as retaining clips, during the process.
Flashlight:
A flashlight will come in handy when inspecting hard-to-see areas inside your shower faucet.
Step 2: Turn Off the Water Supply
Before removing any parts of the shower faucet, turn off the water supply to prevent leaks or water damage. Locate the main water shutoff valve in your home or use the individual shutoff valves for the bathroom if available. Turn the valves clockwise to close them completely.
Once the water is turned off, open the shower faucet to release any residual water trapped in the lines. This step ensures a safe and dry working environment as you proceed with identifying the cartridge model.
Step 3: Remove Handle and Trim Plate
To access the shower cartridge, you’ll need to first remove the handle and trim plate. Begin by locating the screw or screws that secure the handle to the faucet. These are often hidden under a decorative cap, which can be gently pried off with a flathead screwdriver. Once exposed, use the appropriate screwdriver to loosen and remove the screws, then carefully pull the handle away from the wall.

Next, take off the trim plate, which is typically held in place by a series of screws. Unscrew these using a screwdriver, being cautious not to strip or damage them. Once the trim plate is free, put it aside along with the screws to ensure no parts get misplaced. Removing the handle and trim plate will expose the cartridge and allow for further steps in the replacement process.
Step 4: Identify Cartridge Model
With the cartridge now exposed, take a close look at the part for any identifying marks or numbers. Most cartridges have a model or manufacturer number engraved on the body, which will help you find the correct replacement.
If you’re unable to locate a clear identifier, consider referencing the faucet’s user manual or taking a photo of the cartridge to show at a hardware store. Ensuring you identify the correct cartridge model is crucial for a successful replacement and seamless functionality.
Step 5: Remove Cartridge
To remove the cartridge, begin by loosening any screws or fasteners holding it in place using the appropriate tools, such as a screwdriver or an Allen wrench. Carefully pull the cartridge straight out of the housing, applying steady pressure to avoid damaging surrounding components.
If the cartridge is stuck or difficult to remove, try gently rocking it back and forth or use a cartridge puller if necessary. Take your time during this step to ensure the housing remains intact and ready for the replacement cartridge.
Step 6: Install New Cartridge
Before installing the new cartridge, ensure that it matches the specifications of the old one and is free from any defects or debris. Align the new cartridge with the housing, making sure the grooves or notches line up properly.
Gently insert the cartridge into the housing, applying even pressure until it is securely seated. Once in place, tighten any screws or fasteners that were removed earlier to secure the cartridge. Double-check that the cartridge is correctly installed and can move or function as intended without resistance.

Step 7: Reassemble the Faucet
After the new cartridge is successfully installed, reattach the faucet handle, faceplate, and any other removed components in the reverse order of how they were removed. Turn on your water supply and test your shower for any leaks or malfunctions. If everything looks good, congratulations! You have successfully replaced your Delta shower faucet cartridge.
