To adjust the water temperature on Delta shower faucets, follow these steps:
1. Remove the handle: Use a screwdriver to remove the screw holding the handle in place, then pull the handle off.
2. Adjust the rotational limit stop: Locate the rotational limit stop, a small plastic disk with teeth. Rotate it counterclockwise to increase the maximum temperature or clockwise to decrease it.
3. Test the water temperature: Turn on the shower and check the water temperature. If it’s not to your liking, repeat step 2 until you achieve the desired temperature.
4. Reassemble the handle: Put the handle back on and tighten the screw to secure it in place.
5. Enjoy your customized water temperature in your Delta shower!
Anti-scald faucets allow homeowners to adjust the maximum hot water temperature. Lowering the hot water temperature helps prevent small children and the elderly from accidentally burning themselves by turning on only hot water. Delta manufactures a Monitor series of bathroom shower faucets that provide different levels of maximum hot water output.
Delta Shower Cartridges
Delta Faucets has a shower cartridge identifier that includes most of the Delta shower cartridges currently in use. Delta tub and shower faucets are designed to maintain the hot water temperature within 3.6 degrees F to prevent sudden changes in water temperature when someone else in the household flushes the toilet or turns on the dishwasher.
Delta thermostatic tub and shower faucets use TempAssure valves, while pressure balance tub and shower faucets use Delta Monitor valves. Both types of Delta shower faucets have an adjustable handle limit stop. These limit stops need to be properly set to ensure that the hot water temperature does not exceed a preset level.
Getting Started
Adjusting the handle requires following some instructions. Depending on the type of faucet you are adjusting, remove the handle or centerpiece of the control knob. For Delta Monitor Series 1700 and 1800 faucets, insert a small flat screwdriver in the center of the temperature control knob and pry off the plastic centerpiece.
For Series 1300 and 1400 faucets, place a small Phillips screwdriver on the screw in the center of the faucet handle, turn the screw counterclockwise to loosen it, and then pull out the screw. Remove the centerpiece or handle straight off and set it aside. Be careful not to lose the screw.
Adjusting the Handle
Hold the rotational stop dial in the center of the faucet with your thumb and forefinger. The rotational stop has plus and minus markings and several teeth that can be turned to adjust the temperature.
If you have a 1700 or 1800 series faucet, turn the rotational stop dial clockwise to decrease the hot temperature by 2 degrees Fahrenheit for each tooth. For a 1300 or 1400 series faucet, turn the dial counterclockwise one tooth to decrease the temperature by 6 degrees Fahrenheit.
To increase the maximum hot temperature on a 1700 or 1800 series faucet, turn the rotational stop dial counterclockwise. Each tooth turned will increase the temperature by 2 degrees. For a 1300 or 1400 series faucet, turn the dial clockwise one tooth to increase the maximum hot temperature by 6 degrees.
Replacing the Handle
To replace the handle on a 1300 or 1400 Delta series faucet, first turn on the water in the shower and let it mix the hot and cold water together. The Delta shower faucet’s mixing unit starts with cold water and then adds hot water. Let the water run for approximately two minutes.
Next, turn the faucet control clockwise to the hottest position for one minute. Place a thermometer in a plastic cup and fill it with the hot water. Check the maximum hot temperature and make any necessary adjustments. To prevent scalding, do not exceed 120 degrees.
For a 1700 or 1800 series faucet, to replace the handle, check the water outlet temperature and snap the temperature knob into place.
