These pictures depict a typical system in a tri level home. Original radon testing in this Michigan home gave a reading of 6.1 pCi/l. The post-mitigation reading was 0.7 pCi/l, essentially the same as outside air. The most unusual aspect of this system may be its location -- Canton, Michigan, where very few radon problems have been discovered.
Interior View
The piping is sealed into the sump and runs up the wall and out of the house exhausting the gas to the exterior.
Power switch
A switch is mounted in the ceiling to allow the system to be turned off if needed.
Circuit panel
The circuit is clearly marked in the circuit panel.
Pressure Gauge
A pressure qua ge is located on the pipe and used to ensure the system is functioning.
Vacuum Fan
A radon vacuum fan is mounted on the exterior. Rubber couplings top and bottom serve as vibration dampers and permit easy fan removal when it eventually fails. The fan is fastened to the building in this photo; in many homes it is set off by 1/2 inch or so to prevent vibrations through the siding & structure.
PVC Piping
Piping terminates just above the eave, with a 90 degree elbow to divert the exhaust away from the structure.
Exterior View
View of the complete exterior. By terminating the exhaust just under the roof line, but still above the eave (per EPA requirement), the system avoids breaking the architectural envelope. This makes it relatively invisible. On some homes, the gas meter produces more noise than the fan!
