The D-Box/Septic Tank Riser Bundle also creates access for preventive & rejuvenation additives (i.e. Arcan).  These additive can help if you have a drainfield that is starting to get soggy and not accept household wastewater.  With the D-Box/Septic Tank Riser Bundle, monthly additions of additives like Arcan can help your drainfield’s performance.

The D-Box/Septic Tank Riser Bundle comes with Septic-Direct’s 30″ x 36″ Fiberglass D-Plate Adapter that allows you to connect the riser system to a new or existing concrete D-Box.

Made from durable composite fiberglass, the D-Plate is designed to withstand deflection caused by heavy soil loads.  The strength of the 1/4″ fiberglass D-Plate allows for the marriage of the larger diameter poly riser over top of the smaller opening of the square concrete d-box.

The D-Box/Septic Tank Bundle  can also be used over a septic tank opening.  The D-Plate’s large 36″ x 30″ footprint provides coverage and security over any large septic tank opening that you are trying to gain access to with poly risers.

To install, apply the included sealant around the rim of the exposed concrete D-Box or Septic Tank.  Fasten the D-Plate to the D-Box with the concrete fastening screws.  Fasten the adapter ring over the opening of the D-Plate with a 5/16″ x 1″ self-tap screws and sealant.  Adapter Ring Models are listed below.  Use Riser and Lid to extend to grade.  Additional Risers must be purchased for D-Boxes that are deeper than 6″.  A Minimum 1″ of riser exposure from grade is required.
