Jackel Radon/Sump Dome Cover
The Jackel Radon/Sump Dome Cover is a heavy-duty, airtight polyethylene dome designed primarily for radon mitigation and sealed sump access; its molded ports and gasketed fit make it a cost-effective technical solution for sealing basins while reducing air exchange. Compared with pump-focused covers and acoustic-only products on this list, Jackel emphasizes radon control and robust weathering at a lower price point, making it a practical choice when budget and vapor sealing are priorities in a sump cover plus sound-dampening strategy.
