ABSTRACT:
A plumbing fixture has a housing provided with a water inlet and formed with a water outlet and with a circuit pocket. This housing is secured to a support surface. An electrically operated valve in the body between the inlet and outlet has an electrical feed wire energizable for movement of the valve between a closed position blocking flow between the inlet and outlet and an open position permitting such flow. An insert fittable in the pocket is formed with a battery compartment holding a battery. A screw or the like fixed the insert in the pocket. An electrical circuit in the insert connected to the feed wire and to the battery opens the valve on detection of a solid object in front of the housing.
