18-29-424.5 Bathtub and whirlpool bathtub valves.

   Bathtub and whirlpool bathtub valves shall have or be supplied by a water-temperature-limiting device that conforms to ASSE 1070/ASME A112.1070/CSA B125.70 or by a water heater complying with ASSE 1082 or ASSE 1084, except where such valves are combination tub/shower valves in accordance with Section 18-29-424.3. The water-temperature-limiting device required by this section shall be equipped with a means to limit the maximum setting of the device to 120°F (49°C), and, where adjustable, shall be field adjusted in accordance with the manufacturer's instructions to provide water at a temperature not to exceed 120°F (49°C). Access shall be provided to water-temperature-limiting devices that conform to ASSE 1070/ASME A112.1070/CSA B125.70.

   Exception: Access shall not be required for nonadjustable water-temperature-limiting devices that conform to ASSE 1070/ASME A112.1070/CSA B125.70 and are integral with a fixture fitting, provided that the fixture fitting itself can be accessed for replacement.

(Added Coun. J. 10-14-21, p. 37722, Art. IV, § 23)

18-29-424.6 Hose-connected outlets.

   Faucets and fixture fittings with hose-connected outlets shall conform to ASME A112.18.3 or ASME A112.18.1/CSA B125.1.

(Added Coun. J. 10-14-21, p. 37722, Art. IV, § 23)

18-29-424.7 Temperature-actuated, flow-reduction devices for individual fixture fittings.

   Temperature-actuated, flow-reduction devices, where installed for individual fixture fittings, shall conform to ASSE 1062. A temperature-actuated, flow-reduction device shall be an acceptable method for limiting the water temperature to not greater than 120°F (49°C) at the outlet of a faucet or fixture fitting. Such devices shall not be used alone as a substitute for the balanced-pressure, thermostatic or combination shower valves required in Section 18-29-424.3 or as a substitute for bathtub or whirlpool bathtub water-temperature-limiting valves required in Section 18-29-424.5.

(Added Coun. J. 10-14-21, p. 37722, Art. IV, § 23)

18-29-424.8 Transfer valves.

   Deck-mounted bath/shower transfer valves containing an integral atmospheric vacuum breaker shall conform to the requirements of ASME A112.4.2/CSA B125.1.

(Added Coun. J. 10-14-21, p. 37722, Art. IV, § 23)

18-29-424.9 Water closet personal hygiene devices.

(Added Coun. J. 10-14-21, p. 37722, Art. IV, § 23)

18-29-424.10 Head shampoo sink faucets.

   Head shampoo sink faucets shall be supplied with hot water that is limited to not more than 120°F (49°C). Each faucet shall have integral check valves to prevent crossover flow between the hot and cold water supply connections. The means for regulating the maximum temperature shall be one of the following:

   1.   A limiting device conforming to ASSE 1070/ ASME A112.1070/CSA B125.70.

   2.   A water heater conforming to ASSE 1084.

   3.   A temperature-actuated, flow-reduction device conforming to ASSE 1062.
