Abstract: A system for detection of water in a conduit includes a casing attached to the conduit on an exterior of the conduit, a sensor assembly supported by the casing and configured to sense a presence of water within the conduit, and an electronic component contained within the casing. The sensor assembly includes a first probe and a second probe, each having a probe contact accessible within the casing and extending into an interior of the conduit to be exposed in the interior of the conduit. The first probe and the second probe are spaced from each other and electrically isolated from each other. The electronic component is connected to the first probe contact and the second probe contact to place the electronic component in electronic communication with the first probe and the second probe. The conduit may be a vacuum breaker tube positioned between a valve and a plumbing fixture.

Abstract: A door assembly for a restroom stall having first and second opposed side walls and a front opening includes first and second housings defining first and second inner cavities and configured to be mounted on the first and second side walls, first and second doors moveably mounted on the first and second housings, each having opposed inner and outer surfaces that are curved and being moveable along an arcing path between an open position and a closed position. In the open position, the door is retracted within the respective housing and at least partially received in the respective inner cavity, and in the closed position, the door is extended outward of the respective housing relative to the open position. In the closed positions, the first and second doors combine to obstruct the front opening, and in the open positions, the first and second doors permit passage through the front opening.
