Key Features Specs Warranty The 16" x 20" septic tank riser kit raises your septic system access point to ground level, making inspections, pumping, and servicing easier. This height configuration is ideal for systems that require a moderate lift for accessibility without the extra height of larger riser setups. The 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 handle outdoor exposure, moisture, and soil contact without corroding. The fitted cover helps prevent water intrusion and restrict unauthorized access.
