There have been numerous cases of children being stuck on a drain in a swimming pool, hot tub or spa and being unable to get off the drain by themselves due to the enormous suction power. In many horrific cases, sometimes the children caught by these drains are eviscerated, i.e., the suction from the drain literally rips their intestines out of them and they are killed or disabled."
