Delta shower cartridges are a common repair item, and they’re relatively easy to replace. If your shower is leaking or not working properly, it may be time to replace the cartridge. Replacing a Delta shower cartridge is a simple process that can be completed in about 30 minutes. Here are the steps on how to do it.
To begin, you will need to gather a few tools. You will need a Phillips head screwdriver, an adjustable wrench, and a pair of needle-nose pliers. You will also need a new Delta shower cartridge. Once you have all of your tools and materials, you can begin the repair process.
First, you need to turn off the water supply to your shower. There should be a shut-off valve located behind the showerhead. Once the water is turned off, you can remove the showerhead by unscrewing it from the shower arm. Next, you need to remove the handle. There will be a small screw located on the side of the handle. Remove the screw and then pull the handle straight off.
Now you can remove the cartridge. There will be a retaining clip located around the base of the cartridge. Use the needle-nose pliers to remove the retaining clip. Once the retaining clip is removed, you can pull the cartridge straight out of the shower body. To install the new cartridge, simply insert it into the shower body and tighten the retaining clip. Then, replace the handle and the showerhead. Finally, turn the water supply back on and check for leaks.
Identifying the Shower Cartridge Type
Before you begin replacing your Delta shower cartridge, it is essential to identify the correct cartridge type. Mismatched cartridges may not fit properly and can lead to leaks or other issues. Here’s a detailed guide to help you determine the type of cartridge you need:
Handle Type
The handle type is a crucial indicator of the cartridge type. Delta offers three primary handle styles for showers:
- Single-Handle Faucets: These faucets have a single lever that controls both water volume and temperature.
- Two-Handle Faucets: These faucets have separate handles for hot and cold water.
- Valve Trim Only: These faucets require a separate valve body (not included with the cartridge).
Cartridge Series
Delta shower cartridges come in several series, each designed for specific handle types and faucet models. To determine your cartridge series, locate the model number stamped on the faucet or valve body. The model number typically starts with an alphabetic character followed by a series of numbers.
| Handle Type | Cartridge Series |
|---|---|
| Single-Handle Faucets | 1300, 1400, 1700, 500 |
| Two-Handle Faucets | 500, 550, 600, 1300, 1700 |
| Valve Trim Only | 550, 600, 1300, 1700 |
Spindle Length
The spindle length refers to the distance from the center of the cartridge body to the top of the stem. It is measured in inches and is critical for ensuring proper water flow and temperature control. Your faucet’s model number will also include the spindle length information.
By following these steps, you can accurately determine the type of Delta shower cartridge you need. This information will ensure that you purchase the correct replacement cartridge for your specific faucet.
