The principle of massage bathtub

Kohler single speed pump and pneumatic switch as an example: as long as the massage bathtub filled with water in the bathtub, it can be self-sufficient operation. There is a suction nozzle at the bottom of the bathtub. The water is sucked into the pump and then returned to the bathtub by the nozzle installed on both sides of the bathtub.
