Installation Instructions
Installation instructions and additional
components are included with the
interceptor. Read all instructions prior
to installation. This interceptor is
intended to be installed by a licensed
plumber in conformance with all
local codes.
When Installing Interceptor Inside
If your dishwashing sink(s)
discharges into a floor
drain/sink (drain), you
must regulate the flow into
the drain to avoid an
overflow of water onto the
kitchen floor. This can be
done by installing a valve
or flow restriction cap on

Hydrostatic Slabs (or Pressure Slabs)
When installed under a
hydrostatic slab (slab
designed to withstand
upward lift, usually
caused by hydrostatic
pressure) interceptor
must be enclosed in a
watertight concrete vault.

indirectly connected
directly connected
If water is entering the interceptor at excessive temperature (over
150° F), a drain water tempering valve (DTV) and approved backflow
prevention assembly must be installed. Most state and local
plumbing codes prohibit water above 1500 F being discharged into
the sanitary sewer. Water above 1500 F will weaken or deform PVC
Schedule 40 pipe, poly drainage fixtures like interceptors and erode
the coating of cast iron (leading to eventual failure).
ODOR ALERT!
Do not install air
gap on outlet side
of interceptor.

High Water Table Installations
Interceptors and risers are not designed
to withstand water table height in
excess of the top of the unit when buried
(see figure). If it is possible for this to
occur, install the interceptor and risers in
a water -tight concrete vault or backfill
with concrete or flowable fill (wet
concrete and flowable backfill should be
max water table height
for direct burial
poured in stages to avoid crushing the
interceptor). At risk areas include but are not limited to tidal surge areas,
floodplains and areas that receive storm water. Great Basin'"" models
that are direct buried in high water table scenarios must be installed
with an anchor kit. Models G13-50, G13-75, and GB-250 use model AKl
anchor kit. Model GB-500 uses model AK2 anchor kit for use with
deadmen anchors. Models G13-1000, GGI-750 and GGI-1500 use model
AK3 anchor kit for use with deadmen anchors.
Flush -to -Grade Burials
Flush -to -Grade buried installations
(without a riser) are not recommended
for heavy foot traffic areas without the
use of an internal gusset support kit
SGK2 (for G132) or SGK3 (for G133).
Fully Support Base of Unit
Install unit on solid, level surface in
contact with the entire footprint of
unit base; for suspended
installations design trapeze to
support the wet weight of the unit.
Do not partially support unit or
suspend unit using metal
U-channel to create a trapeze.

Support Inlet and Outlet Piping
For above grade installations ensure
heavy inlet and outlet piping (such as
cast iron or long runs) is properly
supported or suspended during the
entire installation process to prevent
connection failure or damage to
bulkhead fittings.
