ABSTRACT:
A suction assembly employs an air induction tube to induct air into the recirculating water pump to cause the pump to cease pumping operation when the front face of the assembly is blocked. The induction tube is connected to a bleed path formed between the induction tube and a surrounding coaxial face tube extended into the assembly from the front face. When the face is blocked by hair or the like, water in the induction tube bleeds into the main chamber of the assembly and empties the induction tube. Air is then pulled into the pump, causing the pump to lose prime thereby reducing pump pressure to zero and allowing the hair or other blocking material to be removed. In a preferred embodiment, the induction tube is connected to the air inlet of at least one venturi-type hydromassage jet assembly. The suction assembly employs a spring-loaded induction stem which bears compressively against the interior face of the suction cover, thereby permitting use of conventional suction covers.
