16” x 20" Septic Tank Riser Kit

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.

Key Features:

• 16" diameter riser with 20" 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:
Suitable for both new and existing septic systems, this riser kit should be installed after confirming the correct tank opening size and riser height. Professional installation is recommended to ensure a proper seal, compliance with local codes, and long-term reliability.

Routine inspection of riser components will help maintain optimal system performance.

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.
