3.3.3 Installing Multiple Trapzilla Units in Series
Alternatively, two Trapzilla Grease Interceptors, Solids Separators or a combination may be installed in
series. A single Trapzilla Solids Separator and Trapzilla Grease Interceptor should always be installed
in series. Place Two-Way Cleanouts before, between and after the units as shown below. Make sure
to connect an outlet vent after the Trapzilla Grease Interceptor. A Low Head Flow Control (LHFC) is
shipped with each grease interceptor and should only be installed after the first Cleanout and before
the first grease interceptor.
*Use a Two-Way Cleanout before and after all
