1 DETERMINE CURRENT RETURN LOCATION AND ANGLE (AS PER PLAN)

PRELIMINARY SITE LAYOUT AND PUMP LOCATION

2 DETERMINE PIPE ROUTING AND ANGLE FROM RETURN TO PUMP LOCATION. ANGLES ARE TO BE

BASED ON FACTORY FITTINGS SUCH AS 11.25°, 22.5°, 45°, 90° ELBOWS ONLY. ROTATE PUMP

TEE TO MEET RETURN PIPE ANGLE.

3 DETERMINE SUCTION DRAIN LOCATION AND PIPE ROUTING AND ANGLE FROM SUCTION

OUTLETS TO PUMP LOCATION. ANGLES ARE TO BE BASED ON FACTORY FITTINGS SUCH AS

11.25°, 22.5°, 45°, 90° ELBOWS ONLY.ROTATE 12" SUCTION 90° ELBOW AS NEEDED TO MEET

SUCTION PIPING ANGLE.

NOTE: RETURN PIPING PLANNING DETERMINES PUMP LOCATION BASED ON ANGLES OF PIPING

REQUIRED TO MEET PROPER INSTALLATION OF RETURN FITTING TO PRODUCE CURRENT

IN DIRECTION OF JUST OFF CENTER OF STREAM CENTERLINE.

PLACEMENT OF RETURN FITTING AND SET ANGLE OF FLOW IS FIRST PRIORITY IN DETERMINING

SYSTEM LAYOUT.
