Physical Installation
Risk of severe injury or death by electrical shock.
• Always disconnect the electrical power before touching the pump or discharge.
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.
• 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 basin that is at least 18 inches (45.7 cm) in diameter and
24 inches (61 cm) deep in accordance with local plumbing codes.
• Clean any debris from the basin.
• Refer to "Typical Installation" on page
2. Place the pump-basin assembly on a hard, level surface.
• Never place the pump directly on clay, earth, or gravel surfaces.
• Do not restrict the intake of the pump as this may damage the seal and starve the pump.
3. Install discharge piping.
• 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 pipe joint compound at all connections.
• If reduced flow rates are required, place a valve on the pump discharge or, if flexible vinyl tubing
is used, a clamp on the tubing.
• Install a union in the discharge line just above the basin cover.
4. Install a full-flow check valve in the discharge line horizontally.
• A ball check valve is recommended.
NOTE: If installed vertically, solids may settle in the valve and prevent it from opening at start-up.

the pump discharge and check valve.
NOTE: If not provided, the pump could "air lock" and will not pump water even though it will run.
6. Install a shut-off valve following the check valve.
7. Secure the pump and switch cords to the discharge line.
8. Place cover over basin.
