Radon System Accessories
RadonAway® radon system fan monitoring devices provide audible and/or visible warnings when the fan ceases to operate. They are ideal for use by professionals as well as homeowners who require reassurance that their radon system is working. The RadonAway® Radon-T was designed specifically to create a stable base for new construction and crawlspace installation and replaces an ordinary PVC tee as the base for RRNC or an active radon, soil gas or moisture control system.
