B: Blocks (If pit depth permits).

C: Discharge pipe (by others). Use flanged fittings. Install check valve and gate valve in each discharge line, on a 45 degree angle if possible. Discharge pipe may come up thru the pit cover or may leave the pit under the cover (thru the pit wall).

D: Inlet. Shoud be away from the control bulbs.

J: Control panel (includes disconnect switches, magnetic starters, control circuitry and alarm).Panel should be in sight of the pump pit and no more than 50 feet from the pit.

M: Electric service line. At start-up, switch leads to insure correct pump rotation.

N: Pit or basin. Concrete pit shown in drawing. May also be steel or fiberglass. Should be deep enough to permit proper pumping cycle without pumping down below the top of the motors.
