ABSTRACT:
An inventive suction cover for a whirlpool bath includes a rearwardly extending disinfectant chamber. The disinfectant chamber is filled with a supply of a disinfectant. As the whirlpool is operated, water is drawn into the disinfectant chamber and mixes with the disinfectant. This water then passes through an outlet hole and into the suction passage along with the greater volume flow of water having passed through the suction cover. The invention allows the retrofitting of a disinfectant chamber into existing whirlpool bath designs, and further ensures a greater likelihood of presence of disinfectant in the suction line at shutdown for draining of the whirlpool.
