4.2 Installing Multiple Trapzilla Units in Series
When installing multiple Trapzilla units in series, the change in elevation from the inlet to the outlet of a
unit requires that each preceding unit be installed 1” higher than the unit after it. For above-ground units,
pressure treated plywood may be placed fully beneath the support stand to create the height difference.
All installations inside of a building must have a vessel vent installed and piped
to atmosphere.

5.0 In-Ground Installation
5.1 Plumbing Instructions for Single Trapzilla Installed In-Ground
A Trapzilla unit may also be installed in the ground outside of the facility. For instances where the facility
drainage piping requires an extension collar that is no more than 18”, use the instructions for the full
TZ-600-ECA unit. If the unit is to be deeper in the ground, the ECA-TZ-29 Extension Collar Assembly
may be installed to align the Trapzilla inlet with the drainage piping. The ECA-TZ-29 may be trimmed
in the field to fit. Trim both the inner and outer portions of the extension collar to make shorter than
collapsed height. Thermaco, Inc. strongly recommends surrounding the in-ground Trapzilla with concrete
to provide additional structural strength and to offset buoyancy effects. For Buoyancy Calculations &
suggested concrete fill quantities please see
page 22
. Use the full TZ-600-ECA for 0-18” of collar needed
or purchase separately the TZ-600 and ECA-TZ-29 for 4-29” of collar needed.
In-Ground Installations inside of a building must have a vessel vent installed and piped to
atmosphere.
* Units using additional extension collars must use adapter lid and/or extension collars included
with unit.
