Everyone has been to a pool area at least more than once in our lifetime. I am sure you have seen the drains around the perimeter of the swimming pools.
Water in a swimming pool should be constantly circulated through a filtering system to get rid of debris and dirt. In a swimming pool filtration system, water flows to the filters through various drains located at the bottom of the pool ( concrete drain covers ).
At the top of the pool are pool drains that continously drain water (debris such as twigs and leaves) from the pool. To protect people from getting hurt by the pool drains around the pool, pool drain covers (known as pool grates or pool gratings) are utilized to cover the pool drains.
