4.3.2 Construction of Riser for TSS-95-SSA installation in series with TZ-1826-SSA
For the installation of a TSS-95-SSA prior to the TZ-1826-SSA, a riser must be constructed to raise the
smaller unit by 8” and provide full support for the weight of the interceptor and its contents.
4.3.3 Installing Multiple TZ-1826-SSA 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 1.5” 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 be piped to atmosphere.
