16" x 14" Septic Tank Riser Kit

The 16" x 14" septic tank riser kit raises your septic system access point to ground level, making inspections, pumping, and servicing more convenient. This mid-height configuration is ideal for tanks at a moderate depth that require added accessibility without the height of larger riser setups. This kit includes a 16" diameter riser, a secure cover, and all required installation hardware. Each component is made from heavy-duty, UV-resistant polyethylene, designed 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 14" 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 can be installed on both new and existing septic systems.
