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 (46 cm) in diam-
eter and 24 inches (61 cm) deep and vented in accordance with local plumbing codes.
• Place as close as possible to the water source to minimize suction piping length.
• 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.
• Place the pump-basin assembly on a hard, level surface.
• Ensure sump is clean and free of nails, gravel, string, cloth, or other debris before installing.
IMPORTANT: Do not attempt to restrict the intake side of the pump.
NOTE: For sump pump applications, an 18 x 22-inch deep perforated basin can be used if in accor-
dance to all applicable plumbing codes.
2. Connect discharge piping, using pipe joint compound at all connections.
• These pumps are available with 1-1/2" FNPT discharge.
• The discharge pipe should be as short as possible and contain as few elbows as possible.
• Piping should be the same diameter as the discharge port.
• If reduced flow rates are required, place a valve on the discharge side of the pump.
• If flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
3. Install a union in the discharge line just above the basin cover.
4. Install a free-flow check valve in the discharge line that will easily pass 3/4-inch solids.
• Install the check valve in a horizontal position or at an angle of no more than 45°.
5. Tape the pump and switch cords to the discharge piping with electrical tape.
6. Drill a 1/8- or 3/16-inch diameter relief hole in the discharge pipe below the floor line and between
the pump discharge and check valve. Refer to
• Drill this hole at a 45° angle below the horizontal plane and away from the pump.
7. Test pump operation. Refer to
8. Confirm that the pump is functioning as intended.
NOTE: It is normal for a stream of water to spray from the air bleed hole in the pump's plumbing.
Confirm that this spray is captured within the basin.
9. Place cover over basin.
