Tuf-tite 12-RIS Septic Riser 12x6 Inch Green Polypropylene

Product Description

The TUF-TITE 12-RIS is a round polypropylene riser designed to extend septic tank or distribution box access to grade level. Measuring 12 inches in diameter and 6 inches in height, this riser provides a stackable, durable solution for bringing buried lids and covers flush with the surface. Constructed from green polypropylene, it resists soil chemicals, moisture, and the compressive loads typical in residential septic installations. Plumbers, septic system installers, and licensed onsite wastewater contractors are the primary trades working with this component.

This riser is used in residential and light commercial onsite wastewater systems where access to septic tank lids, distribution boxes, or pump chambers needs to be raised to or near grade. The round profile and 12-inch diameter suit standard septic tank opening dimensions. It is sold as a single unit and is intended for use with compatible TUF-TITE lids and covers. Stacking multiple risers allows for adjustment to varying burial depths.

Compatibility

Installation Notes

Installation is typically performed by a licensed plumber or certified septic system installer in accordance with local onsite wastewater regulations and state health department requirements. Excavate to expose the tank lid before positioning the riser, and ensure the base seating surface is clean and level for a proper seal. Stack additional risers as needed to reach the desired finish grade, and secure with the appropriate TUF-TITE lid rated for the expected traffic or load conditions. Do not exceed the compressive load rating of the riser stack without verifying structural suitability for the application.
