ABSTRACT:
A suction fitting for use in a water circulation system, the fitting having a perforated body that is mounted to permit fluid flow through both front and rear perforated faces, and thereby minimize the possibility of complete blockage of the fitting by entrapped hair or skin. Operation of a circulating pump is controlled to prevent damage to equipment and property and also to minimize the possibility of serious personal injury or death. The suction fitting further includes a suction tube for connection to the pump, for circulating water in the tub or spa back through jets in the tub or spa, and a pressure sensor line connecting the water in the tub or spa to a water level sensor. The front face of the perforated body has a number of grooves, to provide fluid communication between the pressure sensor line and the suction tube, through one or more front-face perforations. When flow into the suction fitting is blocked, a reduced pressure is sensed immediately behind the front face of the perforated body, through the pressure sensor line and the grooves in the front face, and the pump is disabled to prevent damage or physical injury.
