• The 20" x 5" septic tank riser kit provides a slight height increase to your septic system access point, improving accessibility while maintaining a low-profile appearance. This size is ideal for shallow systems or for fine-tuning the final height of an existing riser setup.

  This kit includes a 20" diameter riser, a secure cover, and the necessary installation hardware. Each component is made from heavy-duty, UV-resistant polyethylene, built to withstand outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover helps prevent water intrusion and limits unauthorized access.

  Key Features:

  • 20" diameter riser with 5" height for septic tank access adjustments
  • 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 both new and existing septic systems. Always confirm your tank opening size and required riser height before ordering. Professional installation is recommended to ensure a proper seal, compliance with local codes, and long-term reliability.

  Routine inspection of the riser and cover will help maintain system 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.
