1. A leak detecting device for swimming pool lights in a water filled swimming pool comprising:
a ring shaped annular resilient seal adapted to contact a surface of the swimming pool underwater and create a seal between the resilient seal and the underwater surface of the swimming pool, the underwater surface being a defined area with a defined perimeter about which the seal engages, the seal having a central opening; the seal being for effecting anchoring in a sealing engagement around the perimeter and being in a stationary non-movable position relative to the defined underwater surface of the swimming pool, the defined underwater surface of the pool being about a component related to being partly in a passage from inside the pool to a position removed from the surface, and such component selectively being a swimming pool light; a rigid housing having a threaded rod extending through said housing, said treaded rod terminating in a suction cup of a resilient material for anchoring said housing to an underwater surface, said housing hollow on its interior, coupled to the resilient seal having an opening therethrough and having an inlet extending into the opening and accessible from the exterior to selectively deliver fluid through the inlet into the interior of the housing, or for coupling a flow meter thereto to detect the flow of water into or out of said housing, or deliver a dye solution for leak detection purposes into the interior of said housing and through the central opening of the resilient seal, the housing being transparent whereby the flow of dye in the hollow housing is observable by a user of the device; the device being for determining leakage underwater within the defined perimeter relative to the defined underwater surface of the swimming pool, and the housing being operable submerged below water level, the threaded rod and suction cup within the housing being visible from outside the housing. |
