Basement & Radon Solutions installed a Sub/Slab Exterior radon system for Stephanie. The radon suction line proposed was installed in the mechanical room basement slab. After diagnostics for system performance, a 5″ diameter hole was drilled through the concrete slab to the earth below. This is where a suction pit was created. A 4″ schedule 40 PVC suction line was installed in the slab, sealed and was extended to the exterior of the home. This is where the radon fan was mounted on the exterior. The radon vent pipe was extended above the roofline to help expel the radon gas safely. The manometer gauge (homeowner radon fan monitoring vacuum gauge) was installed on the suction line pipe in the basement. This 4″ piping system will reduce radon levels in the home up to 33% opposed to using a 3″ suction line pipe. We also installed a Radon System Alarm – They are now required on all newly installed residential radon systems. This unit is a vacuum monitoring device utilizing piezo resistive pressure sensor (PPS) technology. This alarm will provide an audible and visual indication to alert the homeowner when the radon system is not moving sufficient air in the event of a power loss to the system. Lastly, we performed a post radon test that came back at 1.0 pCi/l!
It was a pleasure helping Stephanie make her new home happy, healthy & safe!
