Shutting Off Water Supply and Depressurizing Pipes
Before embarking on the task of replacing your diverter valve, it is crucial to ensure that the water supply to your plumbing system is completely shut off. This will prevent any unwanted water from leaking out during the process and avoid potential damage to your property.
Locating and Closing the Main Water Valve
Typically, the main water valve for your home is located in a basement, utility room, or crawl space. It is usually a large, round handle or a lever that controls the flow of water into your entire plumbing system. To turn off the main water valve, simply turn the handle or lever clockwise until it is fully closed.
Depressurizing the Pipes
Once the main water valve is closed, you will need to depressurize the pipes in your plumbing system. This is necessary to release any remaining water pressure in the pipes, making it easier to work on the diverter valve without encountering sudden bursts of water.
To depressurize the pipes, follow these steps:
| Step | Description |
|---|---|
| 1. | Open the highest faucet in your home, typically in the bathroom or upstairs. |
| 2. | Keep the faucet open until water stops flowing. |
| 3. | Open all other faucets in your home, including those in the kitchen, bathrooms, and laundry room. |
| 4. | Let the faucets run until all the water has drained out and air begins to flow from them. |
Removing the Handle and Trim Plate
1. Remove the Handle
Locate the set screw or grub screw on the base of the handle. Using a hex key or Allen wrench, carefully loosen the screw until the handle can be removed. Handle designs may vary, so if you encounter any difficulty, refer to the manufacturer’s instructions.
2. Detach the Trim Plate
Once the handle is removed, you will see the trim plate secured by screws or clips. Using a screwdriver or trim removal tool, carefully unscrew or unclip the trim plate. Be mindful not to damage the surrounding wall or fixtures. In some cases, the trim plate may slide off once the handle is removed.
3. Disconnect the Cartridge
Behind the trim plate, you will find the cartridge housing, which contains the diverter valve. Unclip or unscrew the cartridge housing to access the diverter valve, which is typically a cylindrical or rectangular component with two or more ports. The cartridge may be held in place by an O-ring or a retainer clip. Inspect the cartridge and its housing for any signs of wear or damage.

| Retainer clip | Secures the cartridge in the housing |
Disconnecting the Old Diverter Valve
Step 4: Removing the Bonnet Assembly
Locate the bonnet assembly, which is typically secured by four screws. Carefully remove these screws, but do not detach the assembly yet. Before you can fully remove the bonnet assembly, you need to release the pressure from the faucet. To do this:
| Type of Diverter Valve | Pressure Release Instructions |
|---|---|
| Pressure balance valve | Using a flat-head screwdriver or Allen key, adjust the cartridge retainer to its highest position. This will release the pressure and allow you to remove the bonnet assembly. |
| Thermostatic valve | Turn off both the hot and cold water supply lines to the faucet. Open the faucet to release any remaining water. Adjust the temperature lever to the hottest setting, then turn off the faucet. This will remove the pressure and allow you to remove the bonnet assembly. |
| Single-handle valve | Turn off the water supply to the faucet. Open the faucet to release any remaining water. Pull up on the handle to remove it from the stem. Once the handle is removed, you can unscrew the bonnet assembly from the faucet body. |
Once the pressure has been released, you can proceed with removing the bonnet assembly. Grip the assembly firmly and pull it straight up until it comes free from the faucet body.
Applying Plumber’s Grease
Locate the O-rings on the new diverter valve and apply a thin layer of plumber’s grease to them. This lubrication will help create a watertight seal and prevent leaks.
Installing the New Diverter Valve
Insert the new diverter valve into the faucet body, making sure that the O-rings are properly aligned with the grooves. Tighten the valve into place using a wrench or pliers.
Once the diverter valve is installed, turn on the water supply and check for leaks. If there are any leaks, tighten the valve further or replace the O-rings.
Setting the Diverter Handle
Before installing the diverter valve handle, make sure to position it in the desired orientation. For most faucets, the handle should be aligned so that it faces the shower head when diverted to the shower setting.
Slide the diverter valve handle onto the valve stem and secure it with a screw or set screw. Make sure the handle moves smoothly and easily between the different settings.
Testing the Diverter Valve
Once the diverter valve handle is installed, test the valve by operating the faucet. The water should flow smoothly from the shower head when the valve is diverted to the shower setting and from the faucet spout when the valve is diverted to the faucet setting.
| Diverter Valve Setting | Water Flow Destination |
|---|---|
| Shower | Shower Head |
| Faucet | Faucet Spout |
If the diverter valve is functioning properly, you have successfully installed and set the new diverter valve.
Reassembling the Trim Plate and Escutcheon Plate
Once the diverter valve is in place, you can reassemble the trim plate and escutcheon plate. Start by aligning the trim plate over the valve body and securing it with the screws. Tighten the screws just enough to hold the trim plate in place, but not so tightly that you strip the threads.
Next, align the escutcheon plate over the trim plate and secure it with the screws. Again, tighten the screws just enough to hold the escutcheon plate in place.
Finally, apply a small amount of silicone sealant around the edges of the trim plate and escutcheon plate. This will help to prevent water from leaking out.
