I recieved a call from a lady living in Jackson, MI that she had her townhouse checked for Radon and it was found to be 6.4. She asked if we could mitigate her place and since I never quote over the phone, I went to look at her situation. The basement of this 2 storey townhouse was finished except for the furnace and utility room. In the furnace room, I observed a 2" sch 40 pipe exiting from the sealed sump crock which had radon written on it, and followed this pipe to the ceiling. I was able to again observe this pipe passing up thru the garage attic through the roof.
The conclusion that I drew from this is a passive radon system installed by the builder was the intent
of this pipe. As for the EPA protocols, this does NOT constitute a passive system that would be effective. (ie: test results)
1) Has anyone else run into this type of sub standard system in their workings?
The 2" pipe is buried behind walls and not easily accesible for replacement nor is the sump a good candidate, due to its location, for a conventional abatement system
2) In the utility room, could a possible answer be to corebore a 3" hole in the concrete floor near an exterior wall to tap into the perimeter drain to allow a conventional active system to be installed or corebore a 3" hole through the slab about 15 feet from the outside wall and excavate and pipe out to conventional system. either way, a new location will be used to accomodate the new 3" sch 40 pvc pipe. Any thoughts about these options?
