On a surge tank inlet from a negative edge gutter what are the ramifications of the entering from the bottom of the tank. Inlet pipe 6", min gradient 1/4" per ft, max flow 120 gpm, water in transit 100 gal, tank below gutter out let, all flow regulators properly in place. I have read that the inlet should be as high in the tank as possible, but water seeks its own level and I can not see the problem of putting the inlet at any level.
