Second Tap Sub-slab Radon System
Radon Mitigation System Information
Second Tap Sub-slab depressurization systems are installed in homes or businesses with slab flooring and are necessary in situations where a single tap or collection point is not adequate enough to bring radon levels in the establishment down to safe levels. This is either due to the amount of radon gas found in the the location or due to the soil found underneath the establishment. The radon mitigation system is made up of PVC Piping. A second tap installation involves running the piping from the sub-slab radon collection points created to the fan that is mounted on the exterior, where the radon gas is expelled from the building through the stack that extends past the roof line. This is a common practice for homes that need more power or collection points to help mitigate the radon from underneath the home or business.
The system works by creating a negative pressure under the home where the radon collection points have been established, with this type of system there are 2 collection points instead of just one. The radon fan that is mounted outside of the building must run continuously in order for the system to work correctly to mitigate the radon from the home or building. From the 2 radon collection chambers under the slab the radon gas is collected and the systems fan will pull the radon gas from under the home out of the radon collection chambers and route the gas safely up through the exterior piping where the gas exits the building out of the radon systems exterior stack.Second Tap Attic Radon Mitigation System
