Adjust the rotational limit stop clockwise to increase hot water

To adjust the hot water temperature on a Delta Monitor shower, one of the key steps is to adjust the rotational limit stop clockwise to increase hot water. This process involves accessing and manipulating a specific component within the shower valve to allow more hot water to flow. Start by turning off the water supply to the shower to ensure safety and prevent any accidental spills during the adjustment. Once the water is off, remove the handle and escutcheon plate to expose the valve cartridge. This may require a screwdriver or Allen wrench, depending on your model.

After exposing the valve cartridge, locate the rotational limit stop, which is typically a small screw or tab positioned near the cartridge. This stop is designed to limit how far the handle can turn toward the hot side, thereby controlling the maximum temperature. Using a screwdriver, carefully turn the rotational limit stop clockwise. Turning it clockwise allows the handle to rotate further toward the hot water side, increasing the amount of hot water that can mix with the cold. Be mindful not to overtighten the stop, as this could damage the mechanism.

As you adjust the rotational limit stop, periodically test the water temperature by turning the shower handle to the hottest setting. This will help you determine if the adjustment is sufficient or if further tweaks are needed. If the water is still not hot enough, continue turning the stop clockwise in small increments, testing after each adjustment. Conversely, if the water becomes too hot, turn the stop counterclockwise slightly to reduce the hot water flow.

It’s important to note that the Delta Monitor shower valve is designed with safety in mind, and the rotational limit stop helps prevent scalding. While increasing the hot water temperature, ensure it remains within a safe range, typically below 120°F (49°C). If you’re unsure about the optimal temperature, consult the user manual or contact Delta customer support for guidance. Properly adjusting the rotational limit stop not only enhances your shower experience but also ensures the longevity of your shower system.

Once you’ve achieved the desired temperature, reassemble the shower handle and escutcheon plate, ensuring all components are securely in place. Turn the water supply back on and test the shower again to confirm the adjustment was successful. If the temperature is still not to your liking, repeat the process, making minor adjustments to the rotational limit stop until you achieve the perfect balance of hot and cold water. This method is straightforward and effective, allowing you to customize your shower temperature with ease.
