5.2 One Solids Separator and One Trapzilla
When installing multiple Trapzilla units in series, the change in elevation from the inlet
to the outlet of a unit requires each preceding unit to be installed 1” higher than the unit
after it.
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.

5.3 Trimming and Setting the ECA-TSS-18 Single-Piece Extension Collar
In-Ground Trapzilla Solids Separator Models
ship with a built-in, single-piece, 18” extension
collar that must be trimmed and then set to the
correct height to bring the Solid Top Cover to
grade.
Follow the steps below to set the extension col-
lar prior to backlling the hole with concrete.
Amount of extension collar needed to bring
Solid Top Cover to grade.
Step 2: Remove the extension collar adapter
ring from the unit with the extension collar still
in place. On the underside of the cover, mark
the excess extension collar length at the bottom
of the four (4) “skirt” portions of the adapter ring.
Check the extension collar height dimension
frequently during this marking to ensure that the
collar has not moved. Extend this mark between
the gaps in the “skirt” so that the collar is marked
all around.
Step 1: With the Solids Separator installed in
its permanent location, raise the telescoping
extension collar to nished grade or oor level.
Measure the height from the top of the unit to this
nished extension collar height and record this
dimension.
Note: If the oor will have a tile covering allow for
the tile thickness when determining the extension
collar height.
