Your shower is one of the most important fixtures in your bathroom. It’s where you start and end your day, and it should be a place where you can relax and rejuvenate. However, if your shower cartridge is faulty, it can make your showering experience a lot less enjoyable.
A faulty shower cartridge can cause a variety of problems, including drips, leaks, and temperature fluctuations. If you’re experiencing any of these problems, it’s important to replace your shower cartridge as soon as possible. Replacing a shower cartridge is a relatively simple task that can be completed in a few hours. In this article, we’ll provide you with step-by-step instructions on how to replace a Delta shower cartridge.
Before you begin, you’ll need to gather a few tools and materials. You’ll need a Phillips head screwdriver, an adjustable wrench, and a new Delta shower cartridge. You can purchase a new cartridge at your local hardware store or online. Once you have all of your tools and materials, you can follow the steps below to replace your shower cartridge.
Identifying the Faulty Cartridge Type
Identifying the faulty cartridge type is crucial to ensure a successful replacement. Here are some steps to help you pinpoint the issue:
1. Determine the Delta Shower Model: Locate the model number engraved on the trim plate or handle. This will help you identify the specific cartridge type used in your shower.
Once you have determined the shower model, you can refer to a cartridge identification chart or contact Delta customer service to confirm the correct cartridge type. Here is a table summarizing common Delta shower cartridge types:
| Cartridge Type | Description |
|---|---|
| RP46074 | Single-handle, pressure-balance cartridge for Delta Monitor series showers |
| RP47475 | Two-handle, pressure-balance cartridge for Delta Wynford series showers |
| RP72140 | Single-handle, thermostatic cartridge for Delta TempAssure series showers |
2. Assess Cartridge Failure Symptoms: Observe the symptoms that prompted the need for replacement. Common signs of a faulty cartridge include difficulty adjusting water temperature or flow, leaks, or a lack of hot water.
3. Remove the Cartridge Assembly: To inspect the cartridge, you will need to remove the handle and trim plate. Shut off the water supply and follow the manufacturer’s instructions for accessing the cartridge assembly.
Removing the Escutcheon and Handle
To begin the replacement process, you’ll need to remove the escutcheon and handle. Here’s a detailed guide on how to do it:
1. Shut Off Water Supply
Before you start, ensure the water supply to the shower is turned off. Locate the shut-off valves under the sink or behind the shower access panel and turn them clockwise to close.
2. Remove the Screws
Using a screwdriver, carefully remove the screws holding the escutcheon in place. The location of the screws may vary depending on the model. Usually, they’re either behind the handle or under a small cap.
3. Pull Off the Escutcheon
Once the screws are removed, gently pull the escutcheon towards you to detach it from the shower body. It may be held in place by a rubber gasket. If you encounter resistance, wiggle the escutcheon side to side while pulling to loosen it.
Below is a table summarizing the steps for removing the escutcheon and handle:
| Step | Description |
|---|---|
| 1 | Shut off the water supply. |
| 2 | Remove the screws holding the escutcheon. |
| 3 | Gently pull off the escutcheon and disconnect the handle. |
Installing the New Cartridge
Re-attaching the handle is the final and supposedly easiest step, but it’s also where things can become complicated. Delta faucets come in a variety of styles and with different handle configurations, so the steps to re-attach the handle may vary slightly depending on the model you have.
Generally, you will need to align the handle with the index mark on the cartridge and then push it onto the stem. You may need to apply some pressure to get it to fit snugly. Once the handle is in place, secure it with the handle screw. Be careful not to overtighten the screw, as this can damage the cartridge.
Tips for Installing the New Cartridge
Here are a few tips to help you install the new cartridge successfully:
| Tip |

1. Align the Handle
Carefully align the handle with the cartridge stem. Make sure it is facing the correct direction.
2. Screw on the Handle
Tighten the handle onto the stem by turning it clockwise. Do not overtighten.
3. Attach the Escutcheon
Slide the escutcheon over the base of the handle and cartridge, aligning the screw holes.
4. Insert the Screws
Insert the screws into the holes and tighten them using a screwdriver.
5. Secure the Escutcheon
Tighten the escutcheon to the wall by turning the screws clockwise.
6. Check for Leaks
Turn on the water supply and check for any leaks around the handle or cartridge.

Restoring Water Supply
After replacing the shower cartridge, it’s essential to restore the water supply to ensure functionality. Follow these steps for proper water supply restoration:
1. Turn on the Cold Water Supply
Locate the cold water supply valve under the sink or near the shower. Turn the valve clockwise to open and allow cold water to flow into the plumbing system.
2. Turn on the Hot Water Supply
Similarly, locate the hot water supply valve and turn it counterclockwise to open. Allow hot water to flow into the system.
3. Check for Leaks
Once both valves are open, check for any leaks around the cartridge, handle, or showerhead. Tighten any loose connections or fittings if necessary.
4. Test the Temperature
Turn on the shower and adjust the handle to achieve the desired water temperature. Ensure that both hot and cold water are mixing correctly.
5. Reset the Showerhead
If the showerhead has a built-in flow restrictor or aerator, it may need to be reset for optimal water flow. Remove the showerhead from the hose and shake it gently to dislodge any debris. Reattach the showerhead and turn on the water to test.
6. Adjust the Flow Rate
If the water flow is too high or too low, adjust the flow rate limiter on the showerhead or valve. Consult the manufacturer’s instructions for specific adjustment procedures.
7. Check for Obstructions
If water is still not flowing properly, check for any blockages in the pipes, hoses, or showerhead. Remove and clean the components as needed.
8. Advanced Troubleshooting
If the above steps do not resolve the water supply issue, consider the following:
| Problem | Solution |
|---|---|
| Low water pressure | Check for clogged pipes, faulty pressure regulator, or inadequate water supply from the main. |
| Water temperature fluctuation | Inspect the mixing valve and thermostatic cartridge for proper operation. Adjust the temperature settings as needed. |
| Persistent leaks | Replace faulty O-rings or gaskets. Check for damaged or misaligned components. |
If the issue persists despite troubleshooting, it’s recommended to consult a qualified plumber for further assistance.
