When it comes to shower faucets, a three-handle faucet is quite common. However, if your three-handle shower faucet is not diverting the flow of water properly, it may be time to replace the diverter valve. Fortunately, replacing the diverter valve in a three-handle shower faucet is a straightforward task and makes for a great DIY project. With the right tools and a little bit of knowledge, you can replace the diverter valve in your three-handle shower faucet in no time.

The first step to replacing the diverter valve in a three-handle shower faucet is to shut off the main water supply to the home. This can usually be found at the ground level in front of your home and is the area where the water company checks the meter. Once you locate the main water supply, simply turn the valve clockwise until it is fully tightened and shut off the water pressure.

Once the main water supply is shut off, you need to drain the water lines in your shower to avoid a mess. To do this, open the faucet all the way and let the water flow out of the shower head or spout. It is also important to cover the drain opening in your tub with a cloth or something else in order to prevent any small pieces from falling in when you are working on the diverter valve.

The next step is to access the cartridge. This is the section of piping that connects the faucet handle to the plumbing behind the shower wall. Generally, you will need to pry off the faceplate to remove the faucet handle. This can be done with a flat head screwdriver. Once you have the handle removed, you can remove any faceplates or escutcheon rings that are blocking access to the cartridge and the diverter valve. After this, unscrew the nut that holds the cartridge in place and slowly remove it from the shower wall.

Now you can remove the diverter stem valve. This is the small plastic wedge that is connected to the back of the cartridge with a nut. Remove the nut and the old diverter stem valve and take care not to damage any of the copper piping, as it is usually quite fragile.

To install the new diverter stem valve, place it in the same location and securely fix the nut. Then, reinstall the cartridge, starting from the back parts and slowly pushing it in until it is completely inside the shower wall. Reattach the handles of the faucet, turn on the main water supply and check that the diverter stem valve works properly and directs the water flow where intended.

This guide should help you replace the diverter valve of your three-handle shower faucet with ease. If you cannot complete this task yourself, it is always best to hire a licensed plumber to decide on the best course of action and get the job done properly. Whether you do it yourself or hire a professional, replacing the diverter valve of your three-handle shower faucet is the best way to ensure your shower works properly.
