The 16" x 8" septic tank riser kit raises your septic system access point slightly above ground level, making inspections, pumping, and maintenance more convenient while keeping a low-profile appearance. This height is ideal for shallow systems or for making minor adjustments to an existing riser setup. 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, built to withstand long-term outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover helps protect against water intrusion and limits unauthorized access. Key Features: 16" diameter riser with 8" 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 is suitable for both new and existing septic systems. Confirm your tank opening size and riser height requirements 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 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.
