Operation - Water Temperature

How can I make sure my shower is safe?
Follow these tips:
- To avoid dangerously hot temperatures, make sure your water heater is set at 120° F or below.
- Install a pressure balance tub and shower valve, such as those found in the broad selection of the Brizo® Monitor® series.
- Set the valve's adjustable rotational limit stop to prevent the temperature handle from being turned to dangerously hot levels.
- Test the tub/shower water with your hand before bathing.
-
How do I set the adjustable rotational limit stop?
Follow these steps:
- Let the water run until both hot and cold water is fully mixed.
- Rotate the handle fully counterclockwise to the hottest position.
- Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.
- If the water temperature is above what is allowed by your local plumbing code (110° F or 120° F), remove the temperature knob on 1700/1800 series, and rotate the rotational limit stop clockwise. For every tooth the rotational limit stop is rotated clockwise, the water temperature will decrease approximately 2° F. Note: If water temperature is too cool, rotate the limit stop counterclockwise.
- After verifying water outlet temperature, snap temperature knob into place.
Make sure cold water flows from the valve first. make sure water (at the hottest flow) does not exceed the temperature allowed (see steps 1-4 above).

The water in the shower is either hot or cold; I can't get any temperature in-between. What's wrong?
The spool and sleeve, the part of the Scald-Guard pressure balance valve that blends the hot and cold water, may not be working properly. This is often caused by mineral deposits that build up over time.
To solve, follow these steps:
- Shut off water supply.
- Remove temperature knob, cover and handle.
- Twist and pull sleeve to remove it.
- Unscrew brass bonnet nut.
Remove cartridge. Soak cartridge in a 50/50 vinegar and water solution for 24 hours to remove any mineral deposits. Note: Unless both hot and cold water supplies are turned on, the pressure balance valve will allow only a dribble of water to flow through the valve.
-
What is a Scald-Guard valve?
A Scald-Guard valve is a Brizo® shower valve feature that keeps you and your family safe from dangerous water temperature fluctuations in the shower and bath. These fluctuations may occur when a toilet is flushed or an appliance, such as a dishwasher, is turned on when the shower is being used. When set correctly, the Scald-Guard valve keeps water temperatures within a pleasing ±3° F, wWhen inlet water temperature is set correctly. This feature is found on all Brizo Monitor® Series tub/shower faucets.
-
What is the adjustable rotational limit stop?
The adjustable rotational limit stop found on Delta Monitor valves, allows you to set a maximum hot water temperature that flows out of the tub/shower. When set correctly, this safety feature ensures that the handle in your tub/shower faucet never goes beyond the set level, resulting in a safe bathing temperature.
-
When or why does the rotational limit stop need to be readjusted?
It may need to be readjusted if the inlet water temperatures change. For example, during the winter, the cold water temperature is colder than it is during the summer, which could result in varying outlet temperatures. Typical temperatures for a comfortable bath or shower range from 90° F to 110° F.
-
Why can't I get enough hot water out of my shower, tub or tub/shower valve?
If hot water supply or temperature is not a problem elsewhere in your house, then it is likely that you have a Brizo® Monitor® pressure balance valve. This valve contains an adjustable Rotational Limit Stop - a small plastic device designed to reduce the risk of scalding. You may adjust the temperature yourself by carefully following the instructions below for adjusting the Rotational Limit Stop:
- Let the water run until both hot and cold water is fully mixed.
- Rotate the handle fully counterclockwise to the hottest position.
- Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.
- If the water temperature is above what is allowed by your local plumbing code (110° F or 120° F), remove the temperature knob and rotate the rotational limit stop clockwise (handle controls volume; temperature knob controls temperature). For every tooth the rotational limit stop is rotated clockwise, the water temperature will decrease approximately 2° F. NOTE: If water temperature is too cool, rotate the limit stop counterclockwise.
- After verifying water outlet temperature, snap temperature knob into place.
- Make sure cold water flows from the valve first. make sure water (at the hottest flow) does not exceed the temperature allowed (see steps 1-4 above).
Important things to remember:
Make sure cold water flows from the valve first and does not exceed 120 degrees Fahrenheit at the hottest flow.
According to industry standards, the maximum allowable temperature of water exiting the valve should not exceed 120 degrees Fahrenheit. (Temperature may vary in your area.) After adjusting water temperature, place a thermometer in a plastic tumbler and hold the tumbler in the water stream to test the temperature. Do not test with hands or any body part. If you have any questions or require further assistance, please contact Customer Service at 1-877-345-BRIZO (2749). A representative will be glad to walk you through these steps over the telephone.
If your water supply or temperature is unacceptable throughout your house, you probably need to adjust the temperature on your water heater. We recommend you follow the instructions of your water heater manufacturer. Typically, water heaters should be set in the "moderate" range, especially if you have small children.
Note: Consumer safety is our number one concern. If you do not have experience with plumbing repairs, we recommend that you contact a licensed plumber for tub/shower repairs.
