ABSTRACT:
A hydraulic suction fuse is mounted in a conventional debris collection trap of a swimming pool, spa or the like, to significantly reduce or eliminate any suction force on the bottom or side wall mounted drain of the swimming pool, spa or the like, as a result of the drain becoming essentially wholly covered by a body part of a person or other drain clogging article. Alternatively, the hydraulic suction fuse may be mounted in a compartment in line between the drain and a suction pump of a swimming pool, spa or the like. Thereby, a person captured by the suction force at the drain will be released and the person is free to move away from the drain essentially instantaneously upon contact with the drain. In one embodiment, the hydraulic suction fuse is self resetting once inflow through the drain is no longer restricted. In another embodiment of the hydraulic suction fuse, the hydraulic suction fuse may be easily manually reset.
