What You'll Learn
Identify Delta Faucet Model
Identifying the correct Delta faucet model is the first crucial step in adjusting the water flow for your Delta shower faucet, such as the 87966 model. Delta faucets come in various designs and series, each with unique features and components. To ensure you are working on the right model, start by locating the faucet’s identification markings. These are typically found on the faucet itself or in the installation manual. For shower faucets, the model number is often stamped on the rough-in valve body, which is hidden behind the wall or trim plate. If you cannot access the valve directly, check the original packaging, receipt, or warranty documents for the model information.
Another method to identify your Delta faucet model is by examining its design and features. Delta’s shower faucets often belong to specific collections, such as the Monitor or Trinsic series, each with distinct aesthetics and functionalities. For instance, the 87966 model is part of the Monitor series, known for its pressure-balancing valve. Look for visual cues like the handle style, spout shape, and finish, as these can help narrow down the model. Additionally, Delta’s website offers a visual identifier tool where you can compare your faucet to images of their products to find a match.
If you’re still unsure about the model, consider removing the faucet handle and trim to inspect the cartridge or valve. Delta uses different cartridges for various models, and identifying the cartridge type can help determine the faucet model. For the 87966, the cartridge is typically a Monitor pressure-balance cartridge, which is distinct from other Delta cartridges. You can compare the cartridge to Delta’s product guides or consult their customer service for assistance.
Once you’ve identified the Delta faucet model, specifically confirming it as the 87966, you can proceed with adjusting the water flow. This model often requires accessing the valve to adjust the flow restrictor or replace components. Knowing the exact model ensures you use the correct tools and replacement parts, avoiding potential damage or incompatibility issues. Always refer to Delta’s official documentation or contact their support team if you encounter difficulties during the identification process.
In summary, identifying your Delta faucet model, such as the 87966, involves checking markings, examining design features, inspecting internal components, and using online resources. Accurate identification is essential for successfully adjusting the water flow and maintaining the faucet’s functionality. With the correct model information, you can confidently proceed with troubleshooting or repairs, ensuring optimal performance of your Delta shower faucet.

Locate and Remove Handle
To begin the process of adjusting the water flow for your Delta shower faucet model 87966, the first crucial step is to locate and remove the handle. Start by identifying the handle assembly, which is typically the lever or knob you use to control the water flow and temperature. On the Delta 87966 model, the handle is usually located at the center of the faucet, directly above the spout. It is often secured with a decorative cap or a small screw that may be hidden underneath. Carefully inspect the handle for any visible screws or caps that need to be removed to access the underlying components.
Once you’ve located the handle, the next step is to remove the decorative cap, if present. This cap is usually at the center of the handle and can often be pried off gently using a flathead screwdriver or a specialized tool designed for this purpose. Be cautious not to scratch or damage the finish of the handle. If there is no decorative cap, look for a small screw underneath the handle. This screw is typically recessed and may require a Phillips or Allen wrench to remove. Loosen and remove the screw carefully, setting it aside in a safe place to avoid losing it during the repair process.
With the decorative cap or screw removed, you can now proceed to take off the handle itself. Grip the handle firmly and pull it straight up and away from the faucet body. In some cases, the handle may be tight due to mineral deposits or corrosion, so a gentle wiggle or slight twisting motion may be necessary to free it. If the handle still resists, avoid applying excessive force, as this could damage the handle or the faucet mechanism. Instead, consider using a handle puller tool, which is specifically designed to remove stubborn faucet handles without causing harm.
After successfully removing the handle, inspect the area beneath it for any additional components, such as an adapter or O-ring, that may need attention during the adjustment process. Take note of the handle’s orientation or any markings that indicate its proper positioning for reinstallation. This step ensures that you can reassemble the faucet correctly once the water flow adjustment is complete. Properly removing the handle is essential, as it grants access to the cartridge or valve assembly, where the flow adjustments will be made.
Finally, set the handle aside in a clean, safe location to prevent it from being misplaced or damaged. With the handle removed, you now have clear access to the internal components of the Delta 87966 faucet, allowing you to proceed with the necessary steps to adjust the water flow. Always handle the components with care to avoid disrupting any seals or mechanisms that could affect the faucet’s performance. This meticulous approach ensures a smooth and effective adjustment process.

Adjust Temperature Limit Stop
Adjusting the temperature limit stop on a Delta shower faucet model 87966 is a straightforward process that ensures your shower water doesn’t get too hot, preventing accidental scalding. The temperature limit stop is a safety feature built into the faucet’s cartridge, and it can be adjusted to suit your preferred maximum temperature. To begin, ensure the water supply to the faucet is turned off to avoid any mishaps during the adjustment process. You’ll need a few basic tools, such as a flathead screwdriver and possibly needle-nose pliers, depending on the accessibility of the cartridge.
Start by removing the faucet handle to access the cartridge. This typically involves unscrewing a screw cover on the handle and then loosening the set screw underneath. Once the handle is removed, you’ll see the cartridge assembly. The temperature limit stop is usually a small plastic or metal piece located on the side of the cartridge. It may be held in place by a clip or screw, depending on the model. Carefully inspect the cartridge to identify the limit stop and the mechanism securing it.
To adjust the temperature limit stop, first release the clip or screw holding it in place. Once freed, you can rotate the stop clockwise to decrease the maximum temperature or counterclockwise to increase it. Make small adjustments and test the water temperature after each change to ensure it’s set to your desired level. Be cautious not to set the temperature too high, as this can pose a safety risk. Once you’ve achieved the desired temperature, reattach the clip or screw to secure the limit stop in its new position.
After adjusting the limit stop, reassemble the faucet by reinstalling the cartridge cover and handle. Ensure all screws are tightened securely, but avoid over-tightening to prevent damage. Turn the water supply back on and test the shower to confirm the temperature adjustment was successful. If the water is still too hot or not hot enough, repeat the process to fine-tune the limit stop.
Regularly checking and adjusting the temperature limit stop is essential for maintaining a safe and comfortable shower experience. If you encounter difficulty during the adjustment process, consult the Delta faucet manual or contact customer support for model-specific guidance. Properly adjusting the temperature limit stop not only enhances safety but also ensures optimal performance of your Delta shower faucet 87966.

Clean or Replace Cartridge
To address water flow issues with your Delta shower faucet model 87966, one of the most effective steps is to clean or replace the cartridge. The cartridge is a critical component that controls water flow and temperature, and over time, it can become clogged with mineral deposits or wear out, leading to reduced flow. Begin by turning off the water supply to the shower to avoid any accidents during the process. Locate the faucet handle and remove it by unscrewing the screw or prying off the cap to access the cartridge. Delta cartridges are typically held in place with a retaining clip, which you’ll need to remove carefully using needle-nose pliers.
Once the cartridge is exposed, gently pull it out of the valve body. Inspect it for signs of damage, such as cracks or excessive wear, or for mineral buildup that could restrict water flow. If the cartridge appears damaged, it’s best to replace it with a new Delta RP32104 cartridge, which is compatible with the 87966 model. However, if the cartridge is in good condition but clogged, proceed with cleaning it. Use a mixture of white vinegar and water to soak the cartridge for about 30 minutes to dissolve mineral deposits. Scrub gently with a soft-bristled brush to remove any remaining debris, ensuring all ports and channels are clear.
After cleaning or replacing the cartridge, reassemble the faucet by inserting the new or cleaned cartridge back into the valve body. Reattach the retaining clip to secure it in place. Reinstall the handle and tighten the screw or cap securely. Turn the water supply back on and test the shower to ensure the water flow has improved. If the flow is still inadequate, double-check that the cartridge is properly seated and the retaining clip is correctly installed.
Replacing the cartridge is a straightforward process, but it’s essential to use the correct replacement part for your Delta model 87966. Always refer to Delta’s official documentation or consult a professional if you’re unsure about any step. Regular maintenance, such as cleaning the cartridge annually, can prevent flow issues and extend the life of your shower faucet.
In summary, cleaning or replacing the cartridge is a key step in adjusting water flow for your Delta shower faucet 87966. By carefully removing, inspecting, and either cleaning or replacing the cartridge, you can restore optimal water flow and ensure your shower functions efficiently. This task requires basic tools and attention to detail but can save you from more extensive plumbing issues down the line.

Reassemble and Test Flow
Once you’ve made the necessary adjustments to the flow restrictor or cartridge to regulate the water flow on your Delta shower faucet 87966, the next critical step is to reassemble the faucet and test the flow. Begin by carefully placing the cartridge back into the valve body, ensuring it is aligned properly with the notches or grooves. Gently push the cartridge all the way in until it sits flush. Reattach the metal sleeve or retaining clip that holds the cartridge in place, making sure it snaps securely into position. This ensures the cartridge remains stable and functions correctly.
Next, reinsert the spout or showerhead assembly, depending on which component you removed during the adjustment process. Thread it back onto the valve body by hand, ensuring it is aligned correctly. Tighten it gently with a wrench or pliers, being careful not to overtighten, as this could damage the threads or seals.

If the flow is still not to your liking, you may need to repeat the adjustment process. However, if the flow is satisfactory, let the water run for a few minutes to ensure there are no leaks around the handles, spout, or escutcheon plate. Wipe away any excess water or debris to inspect the connections thoroughly.
If you notice any leaks, turn off the water supply again and disassemble the faucet to check the seals, gaskets, or threads. Replace any worn components if necessary. Once you’re confident there are no leaks, test the flow again to ensure it remains consistent across all settings. Pay attention to both hot and cold water to confirm the temperature balance is correct.
Finally, after confirming the flow and ensuring there are no leaks, your Delta shower faucet 87966 should be fully functional with the desired water flow. Regularly check for any signs of wear or reduced performance in the future, as this will help maintain optimal functionality. Reassembling and testing the flow carefully ensures that your adjustments are effective and that your shower operates smoothly for years to come.
