16" x 17" Septic Tank Riser Kit

The 16" x 17" septic tank riser kit is designed to raise your septic system access point to ground level, making inspections, pumping, and maintenance more convenient. This height is ideal for systems that require moderate elevation to bring access above the surface without excessive riser height.

This kit includes a 16" diameter riser, a secure cover, and all necessary installation hardware. Each component is made from heavy-duty, UV-resistant polyethylene, engineered to resist corrosion, moisture, and outdoor exposure over the long term. The tight-fitting cover helps reduce water intrusion and restrict unauthorized access.

Key Features:

• 16" diameter riser with 17" height for septic tank access

• Durable, corrosion-resistant polyethylene construction

• Tight-fitting cover for added safety and protection

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

• Includes hardware for installation

Installation Notes:
This riser kit can be installed on both new and existing septic systems. Before ordering, confirm the size of your tank opening and the height required to meet your access needs. Professional installation is recommended to ensure a proper seal, code compliance, and long-term reliability.

Regular inspection of the riser and cover is recommended to maintain system integrity and performance.

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.
