Once you've located the appropriate shutoff valves, the next step is to turn them off. This process varies depending on the type of valve. For traditional gate valves, turn the handle clockwise until it stops, which should shut off the water flow. For ball valves, a quarter-turn of the handle should suffice. It's essential to test the water flow after turning off the valves to ensure they are fully closed. Simply open the shower faucet to confirm that no water is coming out. If water still flows, double-check the valves and ensure they are properly shut off.
Shutting off the water supply is not just about preventing leaks; it’s also about safety. Working on plumbing fixtures with the water running can lead to accidents, such as slipping on wet surfaces or being unable to control the water flow during the replacement. By taking the time to locate and turn off the shutoff valves, you create a safer and more controlled environment for your repair work. This precautionary step is a small investment of time that can save you from significant inconvenience and potential damage.
In summary, shutting off the water supply is a critical preliminary step in replacing a push button diverter in your shower. By locating the shutoff valves and ensuring they are properly closed, you prevent leaks, enhance safety, and set the stage for a successful repair. Whether you're dealing with individual shower valves or the main water supply, taking the time to do this correctly will make the entire process smoother and more efficient. Always verify that the water is off before proceeding with the replacement to avoid any unwanted surprises.

Install New Diverter: Wrap threads with Teflon tape, insert new diverter, secure with gaskets and screws
Replacing a push-button diverter in your shower can seem daunting, but with the right tools and steps, it’s a manageable DIY task. One critical phase of this process is installing the new diverter, which involves wrapping threads with Teflon tape, inserting the new component, and securing it with gaskets and screws. This ensures a watertight seal and reliable functionality, preventing leaks that could damage your bathroom over time.
Step-by-Step Installation: Begin by wrapping the threads of the new diverter with Teflon tape in a clockwise direction. Use 3-4 layers of tape to ensure a tight seal, but avoid overwrapping, as excess tape can cause misalignment. The tape should be smooth and evenly applied, covering the entire threaded area. This simple yet crucial step acts as a barrier against water seepage, which is often the root cause of leaks in shower diverters.
Inserting the Diverter: With the threads properly wrapped, carefully insert the new diverter into the shower valve. Align it straight to avoid cross-threading, which can strip the threads and render the diverter unusable. Gently hand-tighten the diverter until it’s snug, but avoid using excessive force. If resistance is felt, stop and recheck alignment to prevent damage. This step requires patience and precision to ensure the diverter seats correctly in the valve body.
Securing with Gaskets and Screws: Once the diverter is in place, secure it with the provided gaskets and screws. Gaskets should be positioned between the diverter and the shower wall to create an additional seal. Tighten the screws evenly, using a screwdriver or drill with a low torque setting to avoid over-tightening. Over-tightening can crush the gaskets or damage the diverter, compromising its integrity. A firm, even seal is the goal—tight enough to prevent leaks but not so tight that it risks breakage.
Practical Tips for Success: Always test the diverter after installation by running water through the shower. Check for leaks around the diverter and at the handle connection. If a leak is detected, turn off the water supply, disassemble the diverter, and reapply Teflon tape or adjust the gaskets. Additionally, keep a small bucket and towel handy during installation to catch any water that may spill from the pipes. This proactive approach minimizes mess and allows you to focus on the task at hand.
By following these steps and tips, installing a new push-button diverter becomes a straightforward process that saves you from costly plumber fees. The key lies in attention to detail—properly wrapping threads, aligning components, and securing them with care. With this guide, you’ll achieve a leak-free, fully functional shower diverter that enhances your daily bathing experience.

Test for Leaks: Turn water back on, check for leaks, ensure diverter functions properly
Once the new push button diverter is installed, the moment of truth arrives: testing for leaks. This step is crucial, as even a minor leak can lead to water damage, mold growth, or increased utility bills over time. Begin by slowly turning the water supply back on, allowing the pipes to fill gradually. This prevents sudden pressure surges that could dislodge the new diverter or cause hidden leaks to worsen. Watch closely as the water flows—any immediate dripping or seepage around the diverter or adjacent fixtures signals a problem that requires immediate attention.
Next, test the diverter’s functionality by pressing the button and switching between showerhead and tub spout modes. Ensure the transition is smooth and complete, with no residual water escaping from the unused outlet. Incomplete diversion often indicates improper alignment or a faulty seal. While testing, run your hand along the diverter’s base and surrounding areas to detect subtle moisture, which might not be visible but can indicate a slow leak. If the diverter feels secure and dry, proceed to inspect the wall cavity or floor beneath the shower for any signs of dampness, especially if the shower is on an upper level.
For a thorough leak test, let the shower run for at least 5–10 minutes while observing all connections and seals. This extended test period allows water pressure to stabilize and reveals leaks that might not appear instantly. Pay special attention to the diverter’s O-ring or gasket, as these components are common culprits for leaks if not seated correctly. If you notice any issues, turn off the water supply again, disassemble the diverter, and reapply plumber’s tape or silicone grease to ensure a watertight seal before retesting.
Finally, consider the long-term implications of a successful leak test. A properly functioning diverter not only prevents water waste but also extends the lifespan of your shower system by reducing strain on pipes and fixtures. If the diverter passes this test, you’ve likely resolved the issue and can enjoy a reliable shower experience. However, if leaks persist, consult a professional plumber to diagnose deeper issues, such as corroded pipes or structural damage, that DIY repairs cannot address.
