ABSTRACT:
An attachment ring assembly is provided for installation in drain openings. The assembly includes a cylindrical ring body installed in the drain opening, the ring body extending over the entire circumference of the discharge port of the drain opening, the ring body having a relatively small liquid-collecting opening in the lower end of the cylindrical ring. A liquid leak detecting sensor is installed in the liquid-collecting opening. A liquid leak which flows into the drain is dammed by the attachment ring assembly and channelled to flow into the liquid-collecting opening and to the sensor, thereby substantially reducing the time which would otherwise be required to detect the leak.
