Anti-Vortex plate for Pool Suction Lines-Parts

The Anti-Vortex cover was a 1970 addition to the pool industry. Originally designed to prevent vortices in the suction line so the pump will not suck air, causing the pump to run dry and burn out. It also would prevent the suction from making contact with the body and hold the victim under water causing them to drown. The plate is attached to the opening of the suction line by screws. Side wall installation is easy but the main drain is more difficult. The water can be drained or one can dive into the water and attach it while holding their breath. In Jacuzzis the suction is great for the jet suction line, so a cover is a must. There is a law that these covers be used in commercial pools, but it is a good idea to use them in a residential pool. All in all, they are good at preventing a vortex where a pump sucks air and keeps the swimmer safe from the potentially dangerous qualities of the suction intake.
