Notes
The sizing of effluent systems normally requires variable level float(s) controls and properly sized basins to achieve required pumping cycles or dosing timers with non-automatic pumps.

Reserve powered design.

For unusual conditions a reserve safety factor is engineered into the design of every Zoeller^® pump.
