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.
• Place as close as possible to the water source to minimize 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.
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.
• 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.
