3.3 Plumbing Configurations
3.3.1 One TZ-1826
Each Trapzilla unit is shipped with a Low Head Flow Control module (see LHFC box for additional
instructions). When applicable, 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.
*Use a Two-Way Cleanout before and after all
Trapzilla Installations

and codes, including plumbing codes. Installation should be performed by a qualified plumber.

as possible to inlet
when necessary.
3.3.2 Installing Multiple Trapzilla Units in Parallel
Trapzilla Grease Interceptors should be installed in parallel with a Trapzilla Flow Splitter (MFSH-44 or
MFSH-66) 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.
*Use a Two-Way Cleanout before and after all
Trapzilla Installations
