3.3.2 Installing Two Trapzilla Units in Parallel
Two Trapzilla Grease Interceptors should be installed in parallel with a Flow Splitter diverting the flow.
Place Two-Way Cleanouts before, between and after the units as shown below, including before and
after the flow splitter. Make sure to connect an outlet vent after each Trapzilla Grease Interceptor. A
Low Head Flow Control (LHFC) is shipped with each unit, and if needed should only be installed after
the first Cleanout and before the Flow Splitter.

ance with all applicable laws, regulations and codes, including plumbing

3.3 Plumbing Configurations
3.3.1 Installing One Trapzilla Unit
Each Trapzilla unit is shipped with a Low Head Flow Control module (see LHFC box for additional
instructions). This needs to be installed to the inlet of the Trapzilla and connected to a code-approved
air intake. Thermaco, Inc. recommends installation of Two-Way Cleanouts on both the Inlet and Outlet
of Trapzilla
®
in accordance with all applicable laws, regulations and codes.
These cleanouts should
match the size of the Inlet and Outlet Piping (i.e. for 4” plumbing, a 4” cleanout should be used).
A Vent on the Outlet piping is also to be installed in accordance with all applicable laws, regulations and
codes.
