The Original Radon / Sump Dome serves two pressing needs; the need for a universal gas-tight cover to serve the radon mitigation market and the need for a cover to retrofit failing sump and sewage basin covers. The Original Radon / Sump Dome is designed to cover an existing basin, providing a new heavy duty cover to properly contain and vent radon gas and odors. There is no reason to dig up your basement or garage floor to remove the existing sump or sewage basin. Simply remove the old cover and install The Original Radon / Sump Dome over the opening, to create a new, sealed system. The Original Radon / Sump Dome is adaptable with a variety of spaces for different connections and comes with a full range of flanges that fit every size pipe. The removable cover allows for easy access to the pump and has a clear view removable inspection plate.
