ABSTRACT:
A cleaning system for cleaning the interior pump and piping system of a whirlpool spa is disclosed. The device comprises a compartmentalized tank having an intake chamber and an outlet chamber. The outlet chamber is placed into fluid communication with the spa's suction intake fitting. The intake chamber is placed into fluid communication with the spa's jet openings. Cleaning fluid is introduced into the outlet chamber and cycles from the outlet chamber, through the spa's pumps and pipes, through the spa's jet openings, into the intake chamber, and back into the outlet chamber, which is in fluid communication with the intake chamber. From there, the fluid begins the cycle again. A pair of cooperating valve assemblies block fluid communication between the intake chamber and the outlet chamber and force the cleaning fluid out of the device upon the completion of the cleaning operation.
