Identify Diverter Type: Determine if it's a push-button or rotary style for accurate repair
Before attempting any repairs on your Delta shower diverter, it's crucial to identify the type of diverter you have. Delta shower diverters typically come in two styles: push-button and rotary. Accurately determining the type is essential because the repair process, tools, and replacement parts differ significantly between the two. Start by examining the visible components of your shower valve. A push-button diverter features a button that you press to switch water flow between the showerhead and tub spout. In contrast, a rotary diverter uses a knob or lever that you turn to control the water flow direction. Understanding this distinction will ensure you follow the correct repair steps and avoid unnecessary complications.
To identify a push-button diverter, look for a small, round or square button located on the shower valve or faceplate. This button is usually clearly visible and may have a raised or textured surface for easy pressing. When activated, it toggles the water flow between the showerhead and tub spout. If you don’t see a button and instead notice a knob or lever that rotates, you likely have a rotary-style diverter. Rotary diverters often have a more traditional appearance, with a knob that turns clockwise or counterclockwise to change the water flow. Pay close attention to these visual cues to correctly identify your diverter type.
Another way to confirm the diverter type is to test its functionality. For a push-button diverter, press the button and observe if the water flow switches between the showerhead and tub spout. If the button feels stuck or doesn’t change the flow, it’s a clear indication that you have a push-button diverter in need of repair. For a rotary diverter, turn the knob or lever and check if the water flow changes accordingly. If the knob is stiff or doesn’t redirect the water, it confirms you’re dealing with a rotary diverter issue. Testing the diverter’s operation provides practical insight into its type and condition.
If you’re still unsure after visual inspection and testing, consult your shower valve’s user manual or Delta’s product documentation. These resources often include diagrams and descriptions that can help you identify the specific model and diverter type. Additionally, Delta’s website or customer support can provide guidance based on your shower valve’s model number. Taking the time to accurately identify the diverter type will save you time and effort in the repair process, ensuring you use the right tools and replacement parts for a successful fix.
Once you’ve confirmed whether you have a push-button or rotary diverter, you can proceed with confidence to the next steps in the repair process. For push-button diverters, common issues include mineral buildup, worn seals, or a malfunctioning button mechanism. Rotary diverters often suffer from worn cartridges, damaged O-rings, or debris blocking the rotation. Knowing the diverter type allows you to focus on the specific components and techniques needed for repair, ensuring a precise and effective solution to restore your shower’s functionality.

Disassemble Shower Handle: Remove screws and caps to access the diverter mechanism
To begin disassembling the shower handle and accessing the diverter mechanism in a Delta push button shower, start by identifying the type of handle you have. Most Delta shower handles are secured with either a screw or a decorative cap. If your handle has a visible screw, use a screwdriver that matches the screw head (typically Phillips or flathead) to remove it. Turn the screwdriver counterclockwise to loosen and remove the screw, being careful not to strip it. Set the screw aside in a safe place to avoid losing it during the repair process.
For handles without visible screws, look for a decorative cap covering the fastening mechanism. This cap is often part of the handle’s design and may require gentle prying to remove. Use a flathead screwdriver or a thin tool to carefully lift the edge of the cap. Apply even pressure to avoid damaging the handle’s finish. Once the cap is removed, you may find a screw underneath, which can then be taken out using the appropriate screwdriver. If there’s no screw, the handle may be threaded or held in place by a retaining clip, which will need to be released to proceed.
With the screw or cap removed, gently pull the shower handle away from the wall. If it doesn’t come off easily, check for any hidden retaining clips or threads that may still be holding it in place. Some Delta handles have a threaded connection, so you may need to twist the handle counterclockwise while pulling to disengage it. Be patient and avoid forcing the handle, as this could cause damage to the mechanism or the handle itself.
Once the handle is removed, you’ll gain access to the diverter mechanism located behind it. This mechanism is responsible for switching water flow between the showerhead and tub spout. Inspect the area for any visible issues, such as mineral buildup, worn-out seals, or misaligned parts. Take note of the components’ positions and orientations before proceeding with further disassembly or repairs, as this will help during reassembly.
Before moving on to fixing the diverter, ensure all components are clean and free of debris. Use a mild cleaning solution or white vinegar to dissolve any mineral deposits that may be affecting the mechanism’s performance. If you notice damaged parts, such as cracked seals or broken springs, make a note to replace them. Properly disassembling the shower handle and accessing the diverter mechanism is a critical step in diagnosing and resolving issues with your Delta push button shower diverter.
