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.

Use optional model 10-1031 seal failure panel to enable moisture sensor circuit on automatic pump models.

Automatic units Patent No. 8,535,014

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