16" x 38" Septic Tank Riser Kit

The 16" x 38" septic tank riser kit is designed to extend your septic system access point above ground level, making inspections, pumping, and maintenance more convenient—especially for tanks installed deeper underground. By reducing or eliminating the need for excavation, this tall riser kit can help streamline servicing while minimizing yard disruption.

This kit includes a 16" diameter riser, a secure cover, and all necessary installation hardware. The riser components are constructed from heavy-duty, UV-resistant polyethylene, built to withstand outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover helps protect against water intrusion and restrict unauthorized access.

Key Features:

• 16" diameter riser with 38" total height for deep-set septic systems

• Durable, corrosion-resistant polyethylene construction

• Tight-fitting cover for improved safety and protection

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

• Includes installation hardware

Installation Notes:
This riser kit can be used for new or existing septic systems. Confirm your tank opening size and required riser height before ordering to ensure proper fit. Professional installation is recommended for optimal sealing, code compliance, and long-term reliability.

Routine inspections of the riser and cover will help maintain system integrity and performance over time.

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.
