Orenco® Riser Tank Adapters provide a structural, watertight method
of installing an access riser over a tank opening. Depending on the adapter model, it can be cast into the top of a concrete
tank, bonded to a tank with adhesive, or mechanically fastened to a
tank with an adapter bolt-down kit.
Step 1: Determine the tank access riser diameter.
Step 2: Determine the tank access type and shape: either round, square, or grooved.
Step 3: Refer to Tank Adapter Sizing Chart (below) to match the tank access diameter and shape.
Note: Adapters fit standard commercially available PVC ribbed pipe.
