A: The grinder pump will be owned by the drainage district, as is the pressure pipe on private property. The drainage district maintains the grinder pumps.
A motor which can be operated either on DC (direct current) or on single phase AC (alternating current) is called a universal motor. On both AC and DC, it gives approximately the same speed and output. Universal motors often run at dangerously high speed when operated at no load. This means that motor speed will be low at full load, but the speed of the motor will start increasing as the load on the motor decreases.
Synchronous and Induction Motors are two difference types of AC electric motors. AC electric motors are an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts: an outside stationary stator and an inside rotor. Synchronous motors and induction motors are the most widely used types of AC motor.
