STEP 1: 6" Valve Installation
Place a flange gasket on the influent and
effluent tank flanges. Align the holes in the
gasket with the holes in the flange ring on
the tank. Place valves on the flanges
aligning the holes on the valve flange with
the tank flange ring. Please note the
orientation of the valves. The arrows on
the valve covers should be pointing
toward the tank. Install isoplast bolts and
nuts on the influent and effluent flanges.
Snug the nuts to "hand tight", but do not
fully tighten. This will allow for adjustments
during the remainder of the installation.
