Always install a union in the discharge
line, just above the sump pit to allow for
easy removal of the pump for cleaning
or repair.
A check valve must be used in the
discharge line to prevent back flow of
liquid into the basin. The check valve
should be a free flow valve that will eas-
ily pass solids.
CAUTION: For best performance of
check valves when handling solids
install in a horizontal position or at an
angle of not more then 45°. Do not in-
stall check valve in a vertical position as
solids may settle in valve and prevent
opening start-up.
When check valve is used, drill a relief
hole 3/16” in diameter in the discharge
pipe. This hole should be located be-
low the floor line between the pump
discharge and the check valve. Unless
such a relief hole is provided, the pump
could “air-lock” and will not pump water
even though it will run.
A gate valve should follow the check
valve to allow periodic cleaning of the
check valve or removal of the pump.
The remainder of the discharge line
should be as short as possible with a
minimum of turns to minimize friction
head loss. Do not restrict the discharge
to sizes below 2’.
Sewage and effluent applications will
require a separate sump vent. A con-
nection is provided on top of the sump
or cover which must be piped to the
existing building vent or extended out-
side with its own standpipe.
For automatic operation, pump must be plugged or wired into re-
mote float switch or liquid level controller. Installation instructions
included with switches and controllers should be referred to for
installation.
Pump will run continuously if plugged directly into an electrical out-
let. Care should be taken to prevent pump running in a dry sump.
Pump must be installed in a suitable gas tight basin which is at
least 24” in diameter and 30” deep and vented in accordance with
local plumbing codes. Pump must be placed on a hard level sur-
face. Never place pump directly on clay, earth or gravel surfaces.
Pump can be installed with ABS, PVC, polyethylene or galvanized
steel pipe. Proper adapters are required to connect plastic pipe to
pump.
