 While fear of the drain may be counterproductive, children should be taught not to intentionally touch or attempt to block components of a swimming pool recirculation system.As a matter of safety, there should be multiple drains in pools and public fountains, to help reduce dangers of pipe entubement and flume debunkment.In some locales, multiple drains are legally mandated on all public swimming pools, and this is becoming increasingly common in new construction residential pools.
