Basement & Radon Solutions installed a Sub-Slab Exterior radon mitigation system for Greg. The radon suction line was installed in the left front end 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 then was extended to the left front exterior of the home. The radon fan was mounted on the left exterior of the home. The radon vent pipe was then extended above the roofline to expel the radon gas safely. The manometer gauge (homeowner radon fan monitoring vacuum gauge) was installed on the suction line pipe in the basement for easy viewing. This 4″ piping system will reduce radon levels in the home up to 33% opposed to using a 3″ suction line pipe. Then, we installed a Radon System Alarm. Radon System Alarms 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 preformed a post radon test that came back at 1.5 pCi/l!
It was a pleasure helping Greg make his new home happy, healthy, & safe again!
