Description
Extend the reach of your septic tank access without digging or replacing your entire riser system. Aero-Stream riser extension kits are engineered to seamlessly raise an existing septic riser using rugged HDPE components that are built to last.
Each kit includes corrugated pipe, our patented connector flange with safety barrier (U.S. Patent No. 12,523,321), butyl sealant, and hardware. Designed to adapt to 24″ inside diameter corrugated pipe or 24″ inside diameter concrete risers (masonry fasteners not included with kit), the kits are available in multiple extension heights from 6″ inches up to 50″, letting you match the exact clearance required for the site.
Made from HDPE, these extension kits resist cracking, weathering, and corrosion — delivering long-lasting performance with minimal maintenance. The integral safety barrier enhances safety by helping prevent accidental entry when the riser cover is removed.
Ideal for: increasing access depth on existing septic risers, retrofitting systems, or adjusting riser heights post-installation without major excavation. Durable, reliable, and ready to ship — the Aero-Stream riser extension kits make difficult access issues easy.
