Tools Needed: Gather adjustable wrench, screwdriver, pliers, replacement diverter, Teflon tape, and cleaning cloth
Before tackling the task of replacing a Delta push button shower diverter, it's essential to assemble the right tools to ensure a smooth and efficient process. An adjustable wrench is a must-have, as it allows you to grip and turn the diverter's retaining nut with precision, accommodating various sizes without damaging the fixture. A screwdriver, preferably a flathead and Phillips head, will be necessary for removing any screws that secure the escutcheon or handle, depending on your specific Delta model. Pliers, particularly needle-nose or slip-joint, can assist in gripping and maneuvering small components, such as O-rings or clips, that might be difficult to handle with your fingers.
The replacement diverter itself is, of course, the star of the show. When purchasing, ensure compatibility with your Delta shower system by checking the model number and specifications. Teflon tape is another critical component, as it provides a watertight seal between the diverter and the shower arm. Wrap 2-3 layers of tape clockwise around the threads of the shower arm, ensuring a tight seal without over-tightening, which can lead to damage. A cleaning cloth, preferably a soft, lint-free material, is often overlooked but plays a vital role in preparing the work area and components. Use it to wipe down the shower arm, diverter, and surrounding areas, removing any debris, mineral deposits, or old plumber’s tape that could compromise the new installation.
From an analytical perspective, the selection of these tools reflects a balance between versatility and specificity. The adjustable wrench and pliers, for instance, offer adaptability to various sizes and shapes, while the screwdriver and Teflon tape are tailored to precise tasks. This combination ensures that you’re equipped to handle both the expected and unexpected challenges that may arise during the replacement process. Moreover, the inclusion of a cleaning cloth underscores the importance of preparation and attention to detail, as a clean work environment can prevent contamination and ensure the longevity of the new diverter.
Instructively, it’s worth noting that the order in which you use these tools matters. Begin by using the screwdriver to remove the handle and escutcheon, exposing the diverter mechanism. Next, employ the adjustable wrench to loosen and remove the retaining nut, followed by the pliers to carefully extract the old diverter. Once the new diverter is in place, use the Teflon tape to secure it, and finally, reassemble the components, ensuring everything is tightened securely but not overly so. This step-by-step approach minimizes the risk of errors and ensures a professional-quality installation.
Persuasively, investing in high-quality tools and materials, such as a durable adjustable wrench and premium Teflon tape, can make a significant difference in the outcome of your project. While it may be tempting to cut corners, using subpar tools or skipping the cleaning step can lead to leaks, damage, or the need for premature repairs. By prioritizing quality and thoroughness, you not only ensure a successful replacement but also contribute to the overall reliability and functionality of your shower system. This proactive approach ultimately saves time, money, and frustration in the long run.

Shut Off Water: Turn off water supply at the main valve or shower shutoff
Before attempting any plumbing repair, safety and preparedness are paramount. The first critical step in replacing a Delta push button shower diverter is to shut off the water supply. This prevents accidental flooding, water damage, and unnecessary mess during the repair process. Whether you’re a seasoned DIYer or a first-timer, this step is non-negotiable.
Steps to Shut Off Water:
- Locate the Main Valve: If your home has a single main water shutoff valve, it’s typically found near the water meter or where the main water line enters the house. Turn the valve clockwise until it stops to cut off water flow entirely.
- Use the Shower Shutoff (if available): Some showers have individual shutoff valves located near the fixture, often in the basement or behind an access panel. Turn these valves clockwise to isolate the water supply to the shower only.
- Test the System: After shutting off the water, open the shower faucet to release any residual water in the pipes. This ensures the system is fully depressurized and safe to work on.
Cautions:
- Avoid skipping this step, even if you’re in a hurry. Working on a live water line can lead to leaks, spills, or broken pipes.
- If you’re unsure about the location of the main valve or shower shutoff, consult your home’s plumbing diagram or contact a professional for guidance.
Practical Tip: If you’re working on an older plumbing system, the shutoff valves may be stiff or corroded. Use a pair of adjustable pliers for extra leverage, but be careful not to overtighten, as this can damage the valve.
By taking the time to properly shut off the water, you’ll create a safer, cleaner, and more efficient environment for replacing your Delta push button shower diverter. This small but crucial step sets the foundation for a successful repair.

Remove Handle: Pry off handle cap, unscrew handle, and remove escutcheon plate
The first step in replacing a Delta push button shower diverter is to remove the handle, a process that requires precision and the right tools. Begin by prying off the handle cap, which often conceals the screw holding the handle in place. A flathead screwdriver or a specialized tool like a handle puller can be used for this task. Apply gentle but firm pressure to avoid damaging the cap or the finish of the fixture. Once the cap is removed, you’ll expose the screw that secures the handle to the valve stem.
Unscrewing the handle is the next critical step. Use a Phillips screwdriver that fits snugly into the screw head to avoid stripping it. Turn counterclockwise with steady pressure, as these screws can be tight due to mineral buildup or years of use. If the screw resists, consider applying a small amount of penetrating oil (like WD-40) and letting it sit for 10–15 minutes before attempting again. After the screw is removed, carefully lift the handle off the valve stem, taking note of any washers or gaskets that may come with it—these will need to be replaced or reused during reassembly.
Removing the escutcheon plate, the decorative cover surrounding the handle, is the final step in this phase. This plate is typically held in place by screws or clips. If screws are present, unscrew them and set them aside for later. If clips are used, gently pry the plate away from the wall using a flathead screwdriver or a putty knife. Work slowly to avoid cracking the plate or damaging the surrounding tile or wall material. Once removed, the escutcheon plate will expose the valve cartridge and internal components, setting the stage for the next steps in the replacement process.
This sequence—prying off the handle cap, unscrewing the handle, and removing the escutcheon plate—is straightforward but demands attention to detail. Rushing or using excessive force can lead to broken parts or cosmetic damage. Keep track of screws, washers, and other small components in a designated container to ensure nothing is lost. By methodically completing these steps, you’ll gain access to the diverter mechanism, positioning yourself to address the core issue effectively.

Replace Diverter: Unscrew old diverter, clean threads, wrap new one with Teflon tape, and reinstall
A worn-out Delta push button shower diverter can lead to frustrating leaks or water pressure issues. Replacing it is a straightforward DIY task that saves you from costly plumber fees. The process boils down to four key steps: unscrew the old diverter, clean the threads, wrap the new one with Teflon tape, and reinstall it. This method ensures a secure, leak-free connection and extends the life of your shower system.
Begin by unscrewing the old diverter, a step that requires patience and the right tools. Use an adjustable wrench or pliers, but protect the diverter’s finish with a cloth to avoid scratches. Turn counterclockwise, applying steady pressure until it loosens. If it’s stubborn, a penetrating oil like WD-40 can help break the seal. Once removed, inspect the threads for damage or corrosion. Clean them thoroughly with a wire brush or fine-grit sandpaper to ensure a smooth surface for the new diverter.
Next, wrap the new diverter’s threads with Teflon tape, a crucial step often overlooked. Use plumber’s tape (Teflon or PTFE), wrapping it clockwise around the threads in a thin, even layer. Aim for 2-3 wraps, ensuring the tape covers the threads completely but isn’t excessive. This creates a watertight seal without over-tightening, which can damage the threads. For added security, apply a small amount of pipe dope or thread sealant, but avoid overusing it to prevent mess.
Reinstalling the new diverter is the final step. Hand-tighten it first, ensuring it’s aligned correctly. Then, use your wrench or pliers to give it a firm but gentle final turn. Over-tightening can strip the threads or crack the fixture, so stop when you feel resistance. Test the diverter by running water through the showerhead and tub spout, checking for leaks. If everything is secure, you’ve successfully restored your shower’s functionality.
This method is not only cost-effective but also empowers homeowners to tackle common plumbing issues confidently. By focusing on these specific steps—unscrewing, cleaning, wrapping, and reinstalling—you ensure a professional-quality repair. Keep Teflon tape and basic tools on hand for future maintenance, as this process can be applied to other plumbing fixtures. With a bit of care and precision, replacing a Delta push button shower diverter becomes a manageable task for any DIY enthusiast.

Test and Reassemble: Turn water back on, check for leaks, and reattach handle and escutcheon
With the new diverter in place, the moment of truth arrives: it's time to test your handiwork. Before you can declare victory, you must ensure that your repair has not only restored functionality but also maintained the integrity of your shower's plumbing. Start by slowly turning the water supply back on, allowing the pipes to fill gradually. This cautious approach minimizes the risk of sudden pressure spikes that could dislodge connections or reveal hidden leaks. As the water flows, observe the diverter’s operation: does the push button engage smoothly, diverting water seamlessly between the showerhead and tub spout? If so, you’re on the right track.
Next, conduct a thorough leak check, a step that separates a temporary fix from a lasting solution. Inspect all connections, including the diverter itself, the shower arm, and the tub spout. Even a small drip can escalate into a major issue over time, causing water damage or mold growth. Use a flashlight to illuminate hard-to-see areas, and consider running your fingers along joints to detect moisture. If you spot a leak, turn off the water immediately and reassess the connection. Tighten it slightly, but be careful not to overtighten, as this can damage threads or crack components.
Once you’re confident there are no leaks, proceed to reattach the handle and escutcheon. This step is as much about aesthetics as it is about functionality. Align the handle with the diverter’s push button mechanism, ensuring it moves freely without binding. Secure the escutcheon—the decorative plate that covers the wall opening—snugly in place. This not only enhances the shower’s appearance but also protects the internal components from soap scum and moisture. Use a gentle touch when tightening screws to avoid stripping them or cracking the escutcheon.
Finally, step back and admire your work. A successful diverter replacement not only restores your shower’s functionality but also demonstrates your ability to tackle DIY plumbing projects with confidence. Remember, the test and reassembly phase is your opportunity to catch and correct any oversights before they become problems. By taking your time and paying attention to detail, you ensure that your repair stands the test of time, saving you from future headaches and expenses.
