Installation
Installation Skill Requirements:
The installation of a TRST basin
system is a specialized skill, which
requires individuals with a basic
understanding of excavating, pipe
fitting, and electrical wiring.

These instructions are
meant only to be an installation
guide;
therefore,
conditions not covered in these
instructions rely on the experience
and mechanical aptitude of those
installing the system.
Grinder Pump Attachments:
Step 1
Attach the stainless
bracket to bottom of the pump
with two bolts and lock washers
provided. See Figure 1.

Step 2
Apply pipe thread sealant to
discharge piping threads and screw
assembly into the pump discharge.
For
vertical
systems, tighten piping until a

WARNING: To reduce risk of
electric shock, do not connect
conduit to pump.
Excavation :
Step 1
Determine appropriate excavation
based on size of the basin, desired
entrance point of the influent line,
and entrance of power connection.
Step 2
Obtain proper backfill material.
The backfill material provides
as much as 90% of the basin's
support under certain stress
conditions. The installer must be
positive that
correct bed and
backfill materials are utilized per
instructions as follows:
A. Clean and free flowing gravel
with particle size not less than
1/8" nor more than 3/4" in
diameter. Use this description
when ordering or specifying

material is commonly known
as "pea gravel".
B. Stone or gravel crushings with
angular particle size of not
less than 1/8", no more than
1/2" diameter, washed and
free flowing, is acceptable as
an alternative material.
CAUTION:
In
conditions the backfill must be
dry and free of ice. Do not use
other backfill materials. The
basin warranty is automatically
void if materials other than the
recommended bed and backfill
materials are used.
