THE SUMP
The sump should be located at the lowest place in the base-
ment or area to be drained. Floor drains from other areas in
the basement may be tiled into the sump. Drain tile around
a house foundation
can also be tried into the sump, effec-
tively removing water and relieving pressure from this area.
A suitable sump can be a 20" or 24" sewer tile. Sump must
be at least 12" in diameter.
A sump
cover is desirable
to exclude
refuse
from the sump.
Consult
local code
for sump
cover specifications.

PUMP INSTALLATION
Check your local Electrical and Plumbing Codes before in-
stalling pump. You must comply with their rules.
Set the pump on the bottom of the sump, making sure that
it sits solidly and is level. Be sure there is enough space
around the pump to allow the switch free movement as
the sump water level changes. Do not install on clay,
earth, or sand.
[A _
Risk of flooding.
If a flexible
discharge
hose is used, pump
may move around
in sump
when motor
starts. If it moves far enough so that the
switch hits the side of the sump, the switch may stick and
prevent pump from starting. Make sure that pump is se-
cured so that it cannot "walk around" in sump.
NOTE: To avoid backflow into the sump when the pump
shuts off, install a Check Valve, SEARSStock No. 2789, in the
threaded discharge port of pump (390.303302)
or 1-1/2"xl-
1/4" reducer bushing (390.303491).
Reducer bushing is in-
cluded with Model 390.303491.
Be sure arrow on check
valve body points away from the pump. This Check Valve is
equipped
with an air bleed hole to prevent airlocking
the
pump. If using any other check valve, drill 1/8" (3.2 ram)
hole in discharge
pipe just above pump body but below
check valve to prevent air locks.
Use 1-1/4" plastic pipe from Hose Kit No. 27909 for the dis-
charge pipe. Run the discharge pipe to the nearest sewer
outlet or other point of disposal. Use the most direct route
with the fewest turns and elbows possible.
Use Teflon tape to seal threads in plastic pipe. Hand tighten
only.
