We will also provide tips on how to troubleshoot common problems that you may encounter during the installation process. By following these instructions, you can save yourself the time and expense of hiring a plumber.
Before you begin, you will need to gather the following tools and materials:
– New Delta shower cartridge
– Adjustable wrench
– Phillips head screwdriver
– Flat head screwdriver
– Bucket or bowl
– Rags or towels
Identifying the Cartridge Type
Identifying the correct cartridge type is crucial for a successful Delta shower cartridge replacement. Here are some steps to help you determine the type of cartridge your shower uses:
1. Identify the Delta Bathroom Faucet Type
-
Single Handle Faucets: These faucets typically have a single handle that controls both water temperature and flow. They use a pressure balance cartridge, which maintains a consistent water temperature regardless of pressure fluctuations.
-
Dual Handle Faucets: These faucets have a separate handle for temperature and flow control. They use a separate cartridge for each handle, typically a temperature control cartridge and a flow control cartridge.
-
Tub/Shower Faucets: These faucets combine the functions of a sink and bathtub/shower faucet. They may use a diverter cartridge to switch water flow between the sink and bathtub/shower.
2. Remove the Handle
-
Single Handle Faucets: Remove the handle cap using a small screwdriver or hex key. The cartridge retainer clip will be exposed beneath the handle.
-
Dual Handle Faucets: Remove the handle set screws using a screwdriver. Lift the handle off the stem. The cartridge retainer clip will be visible beneath the handle.
3. Inspect the Cartridge Retainer Clip
-
Plastic Clip: Newer Delta faucets use a plastic retainer clip that is either round or triangular.
-
Metal Clip: Older Delta faucets may use a metal retainer clip that is typically round or hexagonal.
Disassembling the Shower Handle
Before replacing your Delta shower cartridge, you’ll need to disassemble the shower handle. Here’s a step-by-step guide:
Step 1: Turn off the water supply
Use the handle under your sink or in your basement to turn off the water supply to your shower.
Step 2: Remove the handle
Delta shower handles are typically secured by a screw or nut. Locate the screw or nut and use a screwdriver or wrench to remove it. Once the screw or nut is removed, you should be able to pull the handle straight off the stem.
| Handle Type | Removal Method |
|---|---|
| Cross Handle | Remove the set screw with an Allen wrench. |
| Lever Handle | Remove the cap and unscrew the handle with a hex wrench. |
| Tub and Shower Handle | Remove the cap and pull the handle straight off the stem. |
Step 3: Remove the trim plate
Once the handle is removed, you’ll need to remove the trim plate. The trim plate is the decorative piece that covers the base of the handle. It is typically held in place by a few screws. Use a screwdriver to remove the screws and then pull the trim plate off.
Testing the New Cartridge
To ensure the new cartridge is functioning correctly, follow these steps:
- Turn on the hot and cold water at the showerhead.
- Check for any leaks around the cartridge or handle.
- Adjust the temperature and pressure to your desired settings.
- Cycle the handle between hot and cold several times to ensure smooth operation.
- Check for any noise or vibration when using the shower.
- If any issues arise, repeat steps 1-6 to ensure proper installation and cartridge function.
- Monitor the cartridge’s performance over time and replace it as needed. Most Delta cartridges have a lifespan of approximately 5-10 years, depending on usage and water conditions. Consider replacing the cartridge proactively if you experience any noticeable decline in performance or water flow.
Troubleshooting Tips:
| Issue | Possible Cause | Solution |
|---|---|---|
| Leaks around the cartridge | Loose or damaged cartridge | Remove the cartridge and reinsert it, ensuring it is securely seated |
| No water flow | Clogged cartridge | Remove the cartridge and clean or replace it |
| Noise or vibration | Damaged cartridge or mineral buildup | Replace the cartridge or remove and clean it if mineral buildup is present |
