Section III: TSS Installation
Plumbing Installation
Locating the Unit
The system should be visible and easily acces-
sible for maintenance and inspection. Options
are available to install Trapzilla Solids Separa-
tors in a basement, suspended from a ceiling
or in-ground in an exterior location. Make sure
adequate room is provided around the unit to
allow easy access for a pump truck operator.
Make sure the height above the Trapzilla access
cover is enough to properly service the system.
Inlet/Outlet Piping
The inlet and outlet piping connections require
flexible sleeve pipe couplings. Keep outlet
piping as straight as possible. Thermaco, Inc.
recommends installation of 4” (100 mm) Two-
Way Cleanouts on both the Inlet and Outlet of
Trapzilla
Interceptors and Solids Separators in
accordance with all applicable laws, regulations
and codes. Use only “sweep” connections. Do
not reduce the pipe sizing on the outlet piping.
Do not install “P” trap on outlet connection of
system. (Note: The system already has a in-
ternal gas trap)
Flow Controls
Trapzilla systems are supplied with a Low-Head
Flow Control module (LHFC-4). This should be
connected to the inlet of the Trapzilla unit in situ-
ations where flow rate needs to be restriced to
75 GPM or when vented flow control is required
by local code.
Venting the Outlet
An outlet vent or approved air admittance valve
of at least 1/2 the diameter of the system’s outlet
connection must be present as close as possible
to the Trapzilla outlet to prevent possible siphon-
age problems. The Vent on the Outlet piping is
to be installed in accordance with all applicable
laws, regulations and codes. Failure to provide
a vent for the system voids Thermaco’s Limited
Warranty for the system.
For High Head Height Applications
Over Six (6) Feet (1.95 m)
For installations where there is head height of
greater than 6 feet (1.95 meters), Thermaco,
Inc. recommends installation of a code-approved
Vented Flow Control Assembly.
Note: Drawings for reference only.
Equipment must be installed in
compliance with all applicable laws,
regulations and codes, includ-
ing plumbing codes. Installation
should be performed by a qualified
plumber.
