Key Features Specs Warranty The 24" x 11" septic tank riser kit is designed to raise your septic system access point closer to ground level, making inspections, pumping, and maintenance more convenient. This shorter configuration is ideal for systems that require only a small increase in height for easier access. The kit includes a 24" diameter riser, a secure cover, and all 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: 24" diameter riser with 11" height for septic tank access Heavy-duty, corrosion-resistant polyethylene construction Tight-fitting cover for 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. 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 inspections of the riser and cover will help maintain optimal 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.
