Over time, it can become faulty or worn out, leading to reduced water pressure, leaks, or the inability to fully switch between the faucet and showerhead. Fixing a shower diverter is a straightforward process that can save time, money, and the need for professional assistance.

Needed Materials

Replacement Shower Diverter

In order to fix a faulty shower diverter, you will need to purchase a replacement diverter. This can be found at most hardware stores or home improvement centers. It is important to make sure you get the correct size and type of diverter for your specific shower setup.

Type of Diverter for Your Specific Shower

Wrench

A wrench will be needed to remove the old diverter and install the new one. The size of the wrench needed may vary depending on the type of diverter and shower system you have.

Plumbers Tape

Plumbers’ tape, also known as Teflon tape, is an essential material for preventing leaks when installing a new shower diverter. This thin white tape is used to create a tight seal between the threads of pipes and fittings. Wrapping the tape around the threads of the shower diverter is recommended before installation.

7 Steps on How to Fix Shower Diverter

Step 1: Turn Off the Water Supply 

Before starting any work on your shower diverter, it is essential to turn off the water supply to prevent leaks and water damage. Locate the main water shut-off valve in your home or the specific shut-off valve for the bathroom.

Turn the valve clockwise until it is fully closed. Once the water is off, open the shower faucet to drain any remaining water in the pipes. This ensures a dry and safe working environment as you proceed with the repair.

Step 2: Remove the Diverter Handle and Plate 

To access the diverter mechanism, you will need to remove the handle and any attached trim plate. Start by locating the screw on the handle, which is often hidden under a decorative cap. Use a flathead screwdriver to gently pry off the cap if necessary.

Once exposed, unscrew the handle screw using the appropriate screwdriver and pull the handle straight out. Next, remove the trim plate by unscrewing the mounting screws that secure it to the wall. Gently set aside the handle and plate, keeping track of all screws and small parts to ensure a smooth reassembly later.

Step 3: Inspect and Clean the Diverter Valve

With the handle and trim plate removed, you can now access the diverter valve. Carefully examine the valve for any signs of wear, mineral buildup, or debris that may be obstructing proper function. Use a flashlight if necessary to get a clear view of the valve components.

Carefully Examine the Valve

To clean the valve, gently scrub away any visible deposits with a soft brush or an old toothbrush. For stubborn buildup, soak a cloth or sponge in a vinegar solution and apply it to the affected areas. Rinse thoroughly with water to remove any residue and ensure the valve is free of debris before proceeding. If the diverter valve is damaged or excessively worn, consider replacing it to restore optimal performance.

Step 4: Replace O-Rings or Washers

Inspect the O-rings or washers on the diverter valve for signs of wear, cracking, or damage. These small components are critical for creating a proper seal and preventing leaks. If they appear worn or brittle, carefully remove them using a small flathead screwdriver or a pick tool, being cautious not to scratch or damage the surrounding parts.

Replace the old O-rings or washers with new ones that match the exact size and specifications of the originals. Apply a small amount of plumber’s grease to the new pieces to ensure a smooth fit and to extend their lifespan. Once installed, double-check that they are seated securely in place before moving on to reassemble the valve.

Step 5: Reassemble the Diverter Handle and Plate

Begin by carefully aligning the diverter handle onto the valve stem. Ensure that it is positioned correctly and fits snugly into place without forcing it, as misalignment can cause damage. Once the handle is seated, secure it using the screw removed earlier. Tighten the screw firmly but avoid over-tightening to prevent stripping or damaging the threads.

Next, reposition the decorative plate over the valve area, ensuring it covers the opening evenly. Attach the plate using the screws you set aside, tightening them evenly to keep the plate flush against the surface. With the handle and plate reassembled, test the diverter by gently turning the handle to confirm it moves smoothly and engages correctly.

Step 6: Test the Diverter

Turn on the water to test the functionality of the diverter. Start by setting the handle to each available position and verify that water flows correctly to the intended fixtures, such as the showerhead or tub faucet.

Check for any leaks around the handle or the decorative plate, as well as proper water pressure. If you notice any issues, double-check the handle’s placement and ensure all screws are secured properly. Once the diverter is operating smoothly, the installation process is complete.

Step 7: Seek Professional Help

If you have followed all of these steps and the diverter is still not working properly, it may be time to seek professional help. A plumber or experienced handyman can diagnose and fix any issues that you are unable to handle on your own.

Following these steps on how to fix shower diverter problems can save you time and money, and help you avoid potential water damage from a malfunctioning diverter. Remember to always turn off the water supply before attempting any repairs, and don’t hesitate to seek professional assistance if needed. Keeping your shower diverter in good working condition will ensure a satisfying and efficient shower experience every time.
