SPECIAL PRECAUTIONS
For Schier Pumpout Port Installations - Failure to follow this guidance voids your warranty
Do not install this unit in any manner
except as described in these instructions.
Doing so may result in property damage, personal injury or death.
DO NOT AIR TEST UNIT OR RISER SYSTEM!

Install interceptor as close as possible
to fixtures being served
Installation Instructions
Installation instructions and additional
components are included with the
interceptor. Read all instructions prior to
installation. This pumpout port is intended
to be installed by a licensed plumber in
conformance with all local codes.
ODOR ALERT!
Interceptor is not a
sewer gas trap.
All upstream fixtures
must be trapped
ODOR ALERT!
Do not install air
gap on outlet side
of interceptor.

directly connected indirectly connected
If water is entering the interceptor at excessive temperature (over
150º F), a drain water tempering valve (DTV) and approved backflow
prevention assembly must be installed. Most state and local
plumbing codes prohibit water above 150º F being discharged into
the sanitary sewer. Water above 150º 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).

Suspended Installations
Design trapeze to support the wet

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.

Fully Support Base of Unit
Install unit on solid, level surface in
contact with the entire footprint of

Hydrostatic/
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.

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 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.
Model GB-75 uses model AK1 anchor kit.

Installations with Risers
Corrugated Riser Pipe
Requirements
Riser adapter model CA2 must be
used when installing interceptors
using 24" diameter corrugated
pipe as a riser. This will adequately
embed the cover adapter in the
concrete slab, preventing
cover/cover adapture failure
under traffic rated loads.
