Installing Pump in Sump
These pumps are usually installed in concrete or fiber-
glass basins with the lift-out rail system. Figure 3 shows
pump mounted on the rail system. Instructions for install-
ing rail system are furnished with rail package.
If pump is not installed with lift-out rail system it must be
properly supported on legs and connected to discharge
pipe so that space is provided under pump for entrance
of sewage. Pump inlet should not be closer than 2 inches
from bottom of sump.
It is not generally
desirable to install
these pumps without
the rail system except
on special O.E.M.
packaged
systems. Check valves
should always be
installed along with
shut-off valves. This
allows for easier
service and prevents
backflow into basin.
