Physical Installation
Risk of severe injury or death by electrical shock.
•
Always disconnect the electrical power before touching the pump or discharge.
•
Check local electrical and building codes before installation. The installation must be in accordance
with their regulations as well as the most recent National Electrical Code (NEC).
Risk of property damage due to flooding.
•
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 basin that is at least 18 inches in diameter and 24 inches
deep in accordance with local plumbing codes.
NOTE: Diaphragm switch models may be used in basins 10 inches in diameter.
•
Clean any debris from the basin.
•

"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. These surfaces contain small
stones, gravel, sand etc. that may clog or damage the pump and cause pump failure.
•
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.
•
Support the pump and piping. Failure to do so may cause the piping to break, the pump to fail,
motor bearing failures, etc.
•
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 for ease of maintenance.
4. Install a full-flow check valve in the discharge line horizontally to prevent back-flow of liquid into the
basin.
•
If installed vertically, solids may settle in the valve and prevent it from opening at start-up.

6. Tape the pump and switch cords to the discharge pipe with electrical tape to keep the power cords
securely routed away from the pump inlet and any control floats.
IMPORTANT: Automatic models using a diaphragm switch include a breather tube that runs through
the power cord. On models with a hardwired connection, this tube extends from the end of the cord. On
models with a plug, the tube is integrated into the plug. Be sure the tube is not obstructed, pinched, or
kinked during installation.
