Abstract
A leak detector apparatus, comprising as an integral part of its construction, an absorbant ring with a conductive strip running around its entire inner surface. The absorbant ring is placed inside a "U" shaped non-conductive ring that has a conductive strip running around the entire inner surface of the inside wall. The leak detector apparatus also comprises a low voltage power supply, a low voltage light, a test switch, a wall plate, and some insulated wire. The assembled rings act as a sensor when placed on the floor, open side down, around the outside of the sewage line flange. Water leaking from where the commode sewage line connects thereby flows towards or collects on parts of the leak detector apparatus, which activates the leak detector, turning on the light and alerting the property owner of the leak by means of the light alarm, thus allowing the owner an opportunity for repairs to be made before water damage occurs.
