When were the water control valves for bathtubs first required to be temperature limiting (single handle)?

Thursday, December 5, 2019

The requirement for a temperature limiting valve for bathtubs (single handle, anti-scald) was begun in the 2006 editions of the International Residential Code (IRC) and the Universal Plumbing Code (UPC), and also applies to whirlpool bathtubs. The Residential Edition of the Florida Building Code followed in 2008 (FBC P2713.3).

The FBC states that: “hot water supplied to bathtubs and whirlpool bathtubs shall be limited to a temperature of not greater than 120°F (49°C) by a water-temperature limiting device that conforms to ASSE 1070 or CSA B125.3, except where such protection is otherwise provided by a combination tub/shower valve in accordance with Section P2708.4."

   While anti-scald valves are one safety precaution to avoid hot water burns in the bathtub, another strategy is to set your water heater thermostat to 120º or 130º F (the “low” to “medium” setting); so that the hot water coming out of any faucet in the house will not quickly scald bare skin—even at straight hot.
