What is a low drain and why shallow end? Are we talking about same thing.?
A floor drain is just like you see in all inground pools. You would have a wall skimmer and a floor drain that supplys water to pump. The floor drain would suck in water from the center and bottom floor of the pool were most dirt collects and would keep it cleaner. Afriend of mine is just getting ready to install one and I might do same but concerned if they could leak longterm.
