ABSTRACT:
A network of conduits are arranged under the foundation of the house. A vent pipe extends from the network conduits to above the house. A slight vacuum is drawn on the network of conduits so that any gases that may exist below the house are drawn into the conduits and discharged into the atmosphere. One of the gases being discharged into the atmosphere is radon. A manual and automatic system is provided for maintaining the vacuum pressure on the network.
