Basement & Radon Solutions installed a Sub-Slab Exterior mitigation system in for Javier. The radon suction line proposed was installed in the left side mechanical closet 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 then created. A 4″ schedule 40 PVC suction line was installed in the slab, sealed and extends to the left exterior of the home. The radon fan was mounted on the left exterior of the home. Then 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 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, 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 preformed a post test that came back at 1.0 pCi/l!
It was a pleasure helping Javier make his home happy, healthy, & safe!
