We were asked to bring this new construction residence up to current ASTM Standards by a local/national builder. The blower motor should never be installed in the basement.
We cut the ducting to ensure a proper suction pit had been dug. We found that there was no suction pit and the vent was actually 6" into the the soil.
After pulling the vent out of the slab and soil. Notice the vent is jammed full of soil.
After talking with the builder, we learned that they had a plumber install the system. Plumbers are normally not certified to do radon mitigation. Bottom line: Make sure any radon mitigation system installed in your home is installed by a certified professional mitigator.
