minimum recommended 8" diametrical clearance around the
tank. Never place the basin directly in contact with rocks or
other sharp objects. Place only fine, 1/8" to 3/4" pea gravel or
1/8" to 1/2" washed, crushed stone as bedding between the
basin and the hole walls. Do not use sand or native soil as
backfill. Properly compact underneath the basin to provide
a solid, level base that can support the weight of the filled
basin. It is recommended that the top lip of the basin be level
with the finished floor.
Initial Backfill: Only fine, 1/8" to 3/4" pea gravel or 1/8" to
1/2" washed, crushed stone should be used around the
bottom of the basin to hold it in place. Do not use sand or
native soil as backfill. Make the inlet connection as required
for particular basin.
Inlet Connection: Pro-Series basins have a 4" inlet molded
to the side of the tank. This inlet is sized to accept a 4"
no-hub type coupling. 1100-Series basins use a hub with a 4"
seal for inlet connection.
Connect the gravity drainage line from the fixtures to this
hub.
be kept out of the backfill material. Only fine, 1/4" to 3/4" pea
gravel, or 1/8" to 1/2" washed, crushed stone is
recommended. Do not use sand or native soil as backfill.
Mound the backfill slightly and allow for natural settling.
Provide access to the basin cover for maintenance and

backfill material as this could cause the tank to collapse.
dual 2" discharge outlets. Do not increase the pipe size
above 2" as adequate flow rates may not be achieved for
proper operation. Discharge sizes may be reduced to 1-1/2"
or 1-1/4". Contact Liberty Pumps with questions regarding
proper pipe sizes and flow rates.
Discharge: Using an adapter, connect the discharge pipe to
the threaded 2" or 3" port provided on the cover.
Install the remaining discharge line. A union should be
installed just above the cover to facilitate pump removal.
A check valve is required after the union to prevent the
backflow of liquid after each pumping cycle. A gate or ball
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 number of turns, to minimize friction head loss.
Contact Liberty Pumps or other qualified person if there are
questions regarding proper pipe size and flow rates.
