A Complete Guide to Fixing Shower Diverter Valves: Easy DIY Solutions

Many people choose to install shower rooms at home because they are very convenient. Nowadays, very few households still install bathtubs. So, how do we repair the shower three-way mixing valve? Today, I will explain this issue in detail, hoping to provide some assistance.

Shower Mixing Valve Repair: When to DIY and When to Call a Professional

1. The shower mixing valve switch handle has a screw hole behind it. Find it, and use a prepared screwdriver to remove the screw inside, allowing you to take off the handle.

2. Once the handle is removed, take off the white plastic piece, the golden metal ring, and the white stainless steel sleeve.

3. After removing the golden metal ring and the stainless steel sleeve, use a screwdriver to detach the plastic components.

4. Next, we’ll see two circular holes at the back of the white plastic component. These holes should connect to the water outlet in the wall. At the interface, you will see waterproof tape wrapped around it. Remove the waterproof tape and then reinstall everything in order. Test to see if there are any leaks.

5. Turn off the water supply and keep the mixing valve dry. If there is still leaking after draining the water, it is likely that there is an issue at the connection point inside the wall, such as a problem with the faucet or the pipe that leads above, possibly due to air in the pipe obstructing the water flow through the mixing valve.

6. In this case, remove the showerhead to allow the air to flow smoothly into the pipe, then quickly pull the switch up and down to drain the water from inside, which should help resolve the issue.

7. After about half an hour, it should stop dripping. Finally, reinstall the shower three-way mixing valve and water valve, which should fix the problem.
