Physical Installation
Risk of damage to pump or other equipment.
• Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump
to fail, motor bearing failures, etc.
• If the relief hole in the discharge pipe is not provided, the pump could "air lock" and will not pump water even
though it will run.
• A missing, improperly installed, or malfunctioning check valve can cause a pump to short-cycle due to back-flow
of the pumped fluid from the discharge plumbing back into the basin, significantly shortening the life of the
pump.
1. Install the pump in the center of a suitable gas tight basin that is at least 18 inches (45.72 cm) in
diameter and 30 inches (76.2 cm) deep and vented in accordance with local plumbing codes.
• Ensure sump is clean and free of nails, gravel, string, cloth, or other debris before installing.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding,
and equipment drainage.
• Never place the pump directly on clay, earth, or gravel surfaces.
IMPORTANT: Do not attempt to restrict the intake side of the pump.
2. Connect discharge piping, using pipe joint compound at all threaded connections.
• The discharge pipe should be as short as possible and contain as few elbows as possible.
• Do not use piping smaller than the pump discharge.
• Use ABS, PVC, polyethylene, stainless steel, or galvanized steel pipe.
• Use pipe joint compound or PFTE tape at all threaded connections.
• For rail systems, use proper adapters to connect nonmetal pipe. Refer to the instructions sup-
plied with the system.
3. Install a union in the discharge line just above the basin cover.
4. Install a full flow check valve in the discharge line that will easily pass ¾ inch (1.91 cm) solids.
• Install the check valve in a horizontal position or at an angle of no more than 45°.
5. Install a gate valve in the discharge line.
6. Tape the pump cords to the discharge piping with electrical tape.
7. Add an air relief bleed hole
• Drill this hole at a 45° angle below the horizontal plane and away from the pump.
8. Install a separate sump vent.
NOTE: A connection is provided on top of the sump or cover which must be piped to the existing
building vent or extended outside with its own standpipe.
9. Connect the pump to an appropriate power supply. Refer to
10. Confirm that the pump is functioning as intended.
11. Place cover over basin.
