Are equalizer lines in public pools subject to the P&SS Act?
Yes. Skimmer equalizer lines are submerged suction outlets and must either be covered with a compliant cover or plugged. CPSC staff does not consider equalizer lines to be main drains. The intended function is not as a drain but rather to prevent air from entering the suction line if the water level in the pool falls below the skimmer opening. With proper maintenance (maintaining water level and clearing baskets) an equalizer line does not present the hazard addressed by the P&SS Act.
