  • Small Phillips screwdriver

  • Small flat screwdriver

  • Thermometer

  • Cup

Tip

Shower faucets with one handle temperature control have a mixing valve inside to mix hot and cold water together. Increasing the rotational stop allows more hot water flow into the mixing valve to increase the total temperature of hot and cold water together.

Warning

Never leave a child unattended in a bathroom. Children may turn the water on full-force in the hot position and burn themselves.

Anti-scald faucets allow homeowner adjustment of the maximum hot water temperature. Lowering the hot water temperature saves small children and the elderly from accidentally turning on hot water only and burning themselves. Among the anti-scald faucets on the market, Delta manufactures a Monitor series of bathroom shower faucets that allow varying degrees of maximum hot water output.

Remove the handle or centerpiece of the control knob, depending on what type of faucet you're adjusting. Delta Monitor Series 1700 and 1800 faucets require that you place a small flat screwdriver in the center of the temperature control knob and pry the plastic centerpiece off. Series 1300 and 1400 faucets require that you place a small Phillips screwdriver on the screw in the center of the faucet handle, turn the screw completely counterclockwise to loosen it, then pull the screw straight out. Pull the centerpiece or handle straight off and set it aside. Don't lose the screw.

Grasp the rotational stop dial in the center of the faucet with a thumb and forefinger. The rotational stop has a plus and minus marking and has several teeth that turn to adjust the temperature.

Turn the rotational stop dial CLOCKWISE to decrease the hot temperature by 2 degrees Fahrenheit for each tooth if your faucet is a 1700 or 1800 series. For a 1300 or 1400 series faucet, turn the dial COUNTERCLOCKWISE one tooth to decrease the temperature 6 degrees Fahrenheit.

Turn the rotational stop dial COUNTERCLOCKWISE to increase the maximum hot temperature by 2 degrees Fahrenheit for each tooth on a 1700 or 1800 series faucet. For a 1300 or 1400 series faucet, turn the dial one tooth CLOCKWISE to increase the max hot temperature 6 degrees Fahrenheit.

Replace the handle on a 1300 or 1400 series faucet.

Turn the water on in the shower and let it mix the hot and cold water together. The mixing unit in the Delta shower faucet starts with cold and then adds hot water. Let the water run for about two minutes.

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. Observe the maximum hot temperature and make adjustments as need be. Do not exceed 120 degrees, to prevent scalding.

Replace the centerpiece on a 1700 or 1800 series faucet.
