ABSTRACT:
A swimming pool leak detector for locating water leaks in a filled swimming pool from a standing position (when the depth of the pool allows) within the swimming pool. The leak detector is machined to resemble a billiard cue and consists of two main parts: a receiver and a plunger. The receiver is machined from a solid plastic rod with a reservoir at its broadest end to accommodate the plunger. A channel is drilled from the tip of the leak detector to the reservoir. The reservoir is filled by submerging the tip of the leak detector into a dye solution (food coloring) and pulling outwardly on the plunger which draws the dye solution into the reservoir. The user then enters the filled swimming pool with the filled leak detector and tests for leaks by placing the tip of the leak detector closely to the point of investigation. By pressing downward on the plunger, a small stream of dye is released, and if a leak is present at the point of investigation, the suction caused by the leak draws the dye solution to the leak, thus pin-pointing the problem.
