ADS-Radon-Dual-Purpose-Sump-Well

The ADS Radon Dual-Purpose Sump Well is a high-density polyethylene (HDPE) sump basin engineered to provide both groundwater collection and radon gas mitigation in residential foundation drainage systems. Designed for new construction and retrofit applications, the sump well incorporates multiple preformed inlet connections for 4-inch perimeter drain pipe and is compatible with both pedestal and submersible sump pumps. When paired with the sealed vented lid kit, the system creates a water-, odor-, and gas-tight sump basin that helps reduce radon infiltration while providing dependable groundwater removal. Its lightweight HDPE construction resists corrosion, simplifies installation, and offers long-lasting performance in below-grade drainage applications.

Usage

The ADS Radon Dual-Purpose Sump Well is installed beneath basement floors where it serves two functions simultaneously. It collects groundwater from foundation drain tile and directs water to a sump pump for discharge, while also functioning as part of a passive or active radon mitigation system. When used with the sealed vented lid kit, the basin helps create an airtight enclosure that allows radon gas to be safely vented outdoors through dedicated vent piping. The molded inlet collars simplify connection to perimeter drainage pipe, making the unit ideal for residential waterproofing, foundation drainage, and radon control systems.
