Abstract: A system adapted to remove radon gas and drainage liquid from a subterranean chamber or basement having a floor and an ambient environment. The system has a drainage channel forming a drainage portion and a venting portion. A valve is located between the drainage portion and the venting portion. Drainage liquid flows into the drainage portion and from the drainage portion through the valve into the venting portion. A pressure gradient is between the drainage portion and the venting portion. The valve substantially prevents the ambient environment from entering the venting portion while allowing drainage liquid to flow from the drainage portion into the venting portion.

Abstract: A control is provided adjacent an overflow of a bathtub or sink. It both remotely controls operation of a basin bottom drain, and provides an option of shutting off flow through the overflow. Rotation of a handle of the control controls the bottom drain, and axial movement of the handle controls flow through the overflow. For example, a clicker-type pop-out valve can control overflow flow. Slot and projection structures restrict use of the overflow shutoff when the drain is not closed, and/or in some circumstances even when the drain is closed.
