16" x 2" Septic Tank Riser Kit

The 16" x 2" septic tank riser kit is designed to provide a slight height increase to your septic system access point, making it easier to reach while keeping a low profile. This configuration is well-suited for shallow systems or for fine-tuning the final height of an existing riser setup.

This kit includes a 16" diameter riser, a secure cover, and the necessary installation hardware. Each component is constructed from heavy-duty, UV-resistant polyethylene, built to handle outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover creates a secure seal to help prevent water intrusion and limit unauthorized access.

Key Features:

• 16" diameter riser with 2" height for septic tank access adjustments

• Heavy-duty, UV-resistant polyethylene construction

• Tight-fitting cover for added safety and protection

• Compatible with most standard septic tank openings (verify dimensions before purchase)

• Includes installation hardware

Installation Notes:
Suitable for both new and existing septic systems, this riser kit should be installed after confirming tank opening size and required riser height. Professional installation is recommended for a proper seal, compliance with local regulations, and long-term performance.

Routine inspections of the riser and cover 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.
