One of the best sources I have come across for radon mitigation with moisture control in mind. Thanks for taking the time for this resources creation. Kudos!
Super helpful!
Great video.... I installed perf 4" pipe under the slab of our new construction home not having any idea if we might have a radon problem. If I don't install an above slab passive or active system now, would if be worth waiting a few months before testing to avoid possible unneeded expense but still have the perf pipe and riser in the basement for future mitigation?
Karl: Having the 4 inch pipe installed is a good thing. However, if you need to route the pipe up later, it may be difficult to install. It would be best to at least make the system passive with the vent pipe all the way up and through the roof (install critter guard on end). Also, allow a vertical space for a possible fan to be installed in the attic space (outside envelope of living space) should you need it. Then complete construction and test home. If need be then you can easily add the fan.
Why not ruin the vent pipe directly outside at the foundation level.... vs running the vent pipe through the house?
Good question. Technically, with an active system where a fan augments the collection, either routing will work provided the discharge point is at least 6 inches above the eave and well away from windows where the exhausted gases will not re-enter. In a passive system (i.e., no fan) if you route it through the interior there will be a small negative pressure inside the pipe due to stack effect that could pull enough radon up and out without the use of a fan. This is called a passive approach. But an outside routing does not provide that stack effect and thus a passive approach will not work. In either case, the house should be tested to verify reductions. If the passive system is inadequate, then space has been allowed in the piping as it is routed through the attic to easily add a fan and further reduce the indoor radon.
