Is your combo tub/shower handle leaking? Don’t despair; you can fix this common plumbing problem in just a few minutes with a few simple tools. The first step is to identify the source of the leak. If the leak is coming from the base of the handle, then it’s likely caused by a worn-out washer. If the leak is coming from the top of the handle, it could be caused by a loose screw or a cracked handle. Once you’ve identified the source of the leak, you can start to make repairs.
Fixing a leak from the base of the handle is relatively easy. You will need a new washer, which can be purchased at any hardware store. Once you have the new washer, simply remove the old washer and replace it with the new washer. You may need to use a pair of pliers to tighten the washer in place. If the leak is coming from the top of the handle, you may need to replace the handle altogether. Replacing a handle is a bit more involved than replacing a washer, but it is still a relatively simple repair. You will need to remove the old handle and install the new handle in its place. Make sure to tighten all of the screws and bolts securely.
Once you’ve made the repairs, turn on the water to check for any leaks. If there are no leaks, then you’ve successfully fixed the leaky combo tub/shower handle. If there are still leaks, then you may need to call a plumber for further assistance.
Identifying the Source of the Leak
The first step in fixing a leaky combo tub/shower handle is to identify the source of the leak. Here are some tips:
- Check the handle packing nut. The handle packing nut is a small, round piece that fits around the base of the handle and helps to seal it against the faucet body. If the packing nut is loose or damaged, it can cause a leak.
- Check the valve stem seal. The valve stem seal is a rubber or silicone washer that sits inside the valve stem and helps to seal the water off when the handle is turned off. If the valve stem seal is worn or damaged, it can cause a leak.
- Check the faucet body. The faucet body is the main part of the faucet and houses the valve stem and handle. If the faucet body is cracked or damaged, it can cause a leak.
- Check the supply lines. The supply lines are the pipes that connect the faucet to the water supply. If the supply lines are loose or damaged, they can cause a leak.
Once you have identified the source of the leak, you can begin to fix it.

The cartridge is a component within the handle assembly that controls the flow of water. A faulty cartridge can cause leaks, so replacing it may resolve the issue. Here are the steps involved in replacing the cartridge:
1. Gather necessary tools and materials:
Tool Purpose Adjustable wrench Tightening and loosening nuts Screwdriver Removing and tightening screws Replacement cartridge Replacing the faulty cartridge 2. Turn off the water supply:
Locate the shutoff valves for the hot and cold water lines underneath the sink or behind the showerhead. Turn the valves clockwise to shut off the water supply.
3. Remove the handle assembly:
Remove the screws securing the handle to the faucet. Use an adjustable wrench to loosen the packing nut behind the handle. Carefully pull the handle assembly straight out.
4. Extract the faulty cartridge:
Use an adjustable wrench to loosen and remove the cartridge retainer nut. Gently pull the cartridge straight out of its housing.
5. Install the new cartridge:
Insert the new cartridge into the housing and tighten the cartridge retainer nut. Ensure the cartridge is properly aligned before tightening.
6. Reassemble the handle assembly:
Reinsert the handle assembly into the faucet, ensuring the cartridge is correctly positioned. Tighten the packing nut and secure the handle with screws.
7. Turn on the water supply and test:
Turn on the shutoff valves to restore water supply. Operate the handle to ensure there are no leaks and the water flow is controlled properly.
Tightening the Packing Nut
If the leak is coming from the handle itself, it is likely that the packing nut needs to be tightened. The packing nut is located behind the handle, and it is responsible for sealing the water around the valve stem. To tighten the packing nut, follow these steps:
1. Turn off the water supply to the shower.
2. Remove the handle by pulling it straight towards you.
3.Locate the packing nut
The packing nut is a large, round nut that is located behind the handle. It is usually made of brass or plastic.
Tighten the packing nut
Use a wrench to tighten the packing nut. Do not overtighten the packing nut, as this could damage the valve stem.
Reinstall the handle
Once the packing nut is tightened, reattach the handle.
If the leak persists, it may be necessary to replace the packing washer. The packing washer is a small, rubber washer that sits inside the packing nut. Over time, the packing washer can become worn or damaged, which can cause the valve stem to leak.
To replace the packing washer, follow these steps:
1. Turn off the water supply to the shower.
2. Remove the handle.
3. Remove the packing nut.
4. Remove the old packing washer.
5. Install the new packing washer.
6. Reinstall the packing nut.
7. Reinstall the handle.Replacing the Handle Assembly
Replacing the handle assembly is a slightly more involved repair, but it is still relatively easy and can be completed in a few hours. Here are the steps on how to replace the handle assembly:
1. Turn off the water supply to the tub/shower.
This is usually done by turning the handle of the shutoff valve located behind the tub/shower.
2. Remove the handle.
This is usually done by removing the screws that hold the handle in place. Once the screws are removed, the handle can be pulled off.
3. Remove the trim plate.
The trim plate is the decorative plate that surrounds the handle. It is usually held in place by screws or clips. Once the trim plate is removed, you will have access to the handle assembly.
4. Remove the handle assembly.
The handle assembly is usually held in place by a nut or screw. Once the nut or screw is removed, the handle assembly can be pulled out. Be careful not to damage the O-rings or gaskets that are located around the handle assembly. Note the position of the handle assembly before removing it, we will need to install the new handle assembly in the same position.
Part Description Cartridge The cartridge is the part of the handle assembly that controls the flow of water. O-rings O-rings are rubber gaskets that create a seal between the cartridge and the handle assembly. Gaskets Gaskets are flat rubber seals that create a seal between the handle assembly and the tub/shower. Adjusting the Stop Screw
Step 5: Tighten or Loosen the Stop Screw
Locate the stop screw, which is usually a small screw located near the base of the handle. Using an Allen wrench or screwdriver, carefully tighten the stop screw clockwise to reduce the flow of water. Alternatively, loosen the stop screw counterclockwise to increase the water flow.
Tightening the stop screw will compress the packing washer, creating a tighter seal and reducing leaks. Conversely, loosening the stop screw will reduce the pressure on the packing washer, potentially allowing for more leaks.
After adjusting the stop screw, turn on the water and check for leaks. If the leak persists, you may need to replace the packing washer or make further adjustments.
Tightening the Stop Screw Loosening the Stop Screw Reduce water flow Increase water flow Compress packing washer Reduce pressure on packing washer Cleaning the Faucet Body
If there is any dirt or grime buildup on the faucet body, it can prevent the handle from sealing properly and causing a leak. To clean the faucet body, follow these steps:
- Turn off the water supply to the faucet.
- Remove the faucet handle by unscrewing the setscrew that is located on the underside of the handle.
- Remove the cartridge or stem from the faucet body. Refer to the manufacturer’s instructions or check online for specific instructions on how to remove the cartridge or stem on your particular faucet model.
- Clean the aerator by removing it from the faucet spout and soaking it in a solution of equal parts vinegar and water for about 30 minutes.
- Clean all the parts of the faucet with a soft cloth and mild dish soap.
- Reassemble the faucet in reverse order of disassembly, making sure to tighten all of the connections securely.
- Turn on the water supply and check for leaks.
Tools You’ll Need Phillips head screwdriver Allen wrench Adjustable wrench Soft cloth Mild dish soap Vinegar Replacing the O-Rings
The O-rings are small, rubber rings that create a seal between the handle and the valve body. Over time, the O-rings can become worn or damaged, allowing water to leak out. Replacing the O-rings is a relatively simple and inexpensive repair that can be done in just a few minutes.
To replace the O-rings, you will need the following tools and materials:
- Phillips screwdriver

Plumber’s tape, also known as polytetrafluoroethylene (PTFE) tape, is a thin, white tape used to seal threaded connections. It’s essential to wrap the tape correctly to ensure a watertight seal.
- Use the correct tape: Verify that you’re using plumber’s tape specifically designed for water applications.
- Unwind the tape: Unwind about 5-6 inches of tape from the roll.
- Stretch the tape: Gently stretch the tape lengthwise by pulling on both ends. This increases its sealing properties.
- Wrap clockwise: When wrapping the tape around the shower handle threads, ensure you wrap in a clockwise direction.
- Apply even pressure: As you wrap, apply firm, even pressure to ensure it adheres properly.
- Overlapping: Wrap the tape with about 50% overlap to create multiple layers of protection.
- Avoid overtightening: Once the tape is applied, hand-tighten the shower handle. Don’t overtighten, as this can crush the tape and create leaks.
- Excessive tape: While it’s essential to use enough tape, avoid using too much. Excessive tape can clog the threads and restrict water flow.
