24" x 44" Septic Tank Riser Kit

The 24" x 44" septic tank riser kit is designed to bring your septic system access point well above ground level, making inspections, pumping, and maintenance more convenient. This extra-tall configuration is ideal for systems installed deeper underground, helping reduce or eliminate the need for excavation during servicing.

This kit includes a 24" diameter riser, a secure cover, and all necessary hardware for installation. Made from heavy-duty, UV-resistant polyethylene, the riser components are built to handle long-term outdoor exposure, moisture, and soil contact without corroding. The cover fits tightly to help prevent water intrusion and restrict unauthorized access.

Key Features:

• 24" diameter riser with 44" total height for deep-set septic systems
• Durable, corrosion-resistant polyethylene construction
• Tight-fitting cover for added safety and protection
• Compatible with most standard septic tank openings (verify dimensions before purchase)
• Includes hardware for installation

Installation Notes:

This riser kit can be installed on new or existing septic systems. For best results, confirm the tank opening size and required height before purchase. A licensed septic professional is recommended for installation to ensure proper sealing, code compliance, and long-term reliability.

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