  • Patent number: 9846071
    Abstract: The pool water level and vacuum monitor is a device that is adapted to be seated on a pool deck adjacent to a swimming pool, and which monitors water level when filling a pool liner whilst a vacuum is removing air from behind a pool liner and a concrete wall of a pool. Moreover, the pool water level and vacuum monitor includes a telescoping armature that extends aside of a housing. The telescoping armature includes a cord and a float member on a distal end of the cord. The float member is adapted to rest on a pool surface of the swimming pool, and moves to close a float switch integrated in the float member. The float switch is able to turn off all circuitry associated within the housing.
