• The 20" x 26" septic tank riser kit raises your septic system access point to ground level, making inspections, pumping, and servicing more convenient.

Each component is constructed from heavy-duty, UV-resistant polyethylene, built to withstand long-term outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover helps prevent water intrusion and restricts unauthorized access.

  Key Features:

  • 20" diameter riser with 26" height for septic tank access

  • Heavy-duty, corrosion-resistant polyethylene construction

  • Tight-fitting cover for added safety and protection

  • Compatible with most standard septic tank openings (verify measurements before purchase)

  • Includes installation hardware

  Installation Notes:
  This riser kit can be installed on new or existing septic systems. Before ordering, confirm your tank opening size and the riser height needed for your setup. Professional installation is recommended to ensure proper sealing, compliance with local codes, and long-term reliability.

  Routine inspections of the riser and cover will help maintain performance and prevent water intrusion.

  Note: Dimensions shown are for the kit base. This model includes a 3" safety pan with an inner diameter of 20" due to a slight bevel. Dome lids add approximately 1" to overall height. Upgrades to flat lids are available for an additional cost. Remove any existing concrete lid before installation. Please confirm diameter and height before ordering. Return shipping costs for incorrectly ordered sizes are the customer’s responsibility.
