Schier Pp2 Installation guide

  • Hello! I've reviewed the installation guide for the SCHIER PP2 Pumpout Port Kit, which is designed for use with Grease Interceptor models GB-50, GB-75, and GB-250. This document provides a clear step-by-step process for installation as well as important precautions to follow with these products. I am ready to answer any questions you might have about the installation process, features, or specifications detailed in the manual.
  • What is the maximum number of elbow fittings allowed in the pumpout plumbing?
    What is the maximum height from the static water line of the interceptor to the hook-up?
    What is the maximum horizontal distance from the interceptor to the pumper truck?

PP2 Installation Guide
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 the sink piping that discharges into the drain. See drawing above for
guidance. For detailed guidance on indirect connections, go to:
hp://webtools.schierproducts.com/Technical_Data/Indirect_Connections.pdf
SPECIAL PRECAUTIONS
For All Schier Grease Interceptor Installations - Failure to follow this guidance voids your warranty
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.
Models GB-50, GB-75, and GB-250 that are direct buried in high water
table scenarios must be installed with model AK1 anchor kit.

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
High Temperature Kitchen Water
If water is entering the interceptor at excessive temperature (over 140º F), a
drain water tempering valve (DTV) and approved backflow prevention assembly
must be installed. Most state and local plumbing codes prohibit water above
140º F being discharged into the sanitary sewer. Water above 140º 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).
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.

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.

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

PP2 Installation Guide
See "INSTALLATION IDEAS" for guidance. Choose an unused outlet on the interceptor to convert
into a pumpout port and choose a location for the pumpout hook-up. NOTE: This kit does not include
the plumbing from the interceptor to the hook-up location. You will need to plan out the pumpout
plumbing based on site conditions and local codes and provide all additional piping, valves,
connections and hardware needed to complete this installation.

Loosen, but do not remove the flexible
coupling clamps. Slide small end of coupling
onto pumpout adapter and tighten clamp.
Slide internal pipe assembly onto desired internal connection stub. Ensure piping
assembly is pointed down (as shown) and there is at least 1/2" of clearance
between the pipe and floor of unit. Securely tighten flexible coupling clamps.
PP2 Installation Guide
Install 3" or 2" PVC piping, connections, valves and/or
hardware from the interceptor pumpout port to pumpout
hook-up location (Not included with this kit). Maximum
quantity of 6 elbow fiings. Max. height from static water line
of interceptor to hook-up is 21 feet. Max horizontal distance
from interceptor to pumper truck (including hose) is 100 feet.
For GB-50 or GB-75, cut internal pipe at premarked
location and keep the section marked for intended unit.
For GB-250, use entire length of supplied pipe.
GB-250
3b
Use PVC primer/cement to assemble internal
vertical pipe, elbow and pumpout adapter.
5a
At the end of the pumpout plumbing line, install a 3" MPT pipe
nipple (Not included with this kit) using a coupling of your choice.
Run Sinks to ensure
interceptor is full of
water. Aach pumper
hose to 3" cam and
groove fiing. Turn on
pump, make sure
interceptor is
pumped out and
inspect pumpout
plumbing for leaks.
5b
Securely aach supplied 3" Cam
and Groove Fiing to pipe nipple
using pipe thread sealant or tape.
