发明名称 Water-escape device for freeze-prone water conduit
摘要 A water-escape conduit connector for use in the exterior above-ground vertical section of a water-discharge conduit having an interior vertical conduit segment communicating with a sump pump container or liner 14. The water-discharge conduit comprises an upstream segment, between the sump pump liner and the water-escape connector, and a downstream segment between the water-escape connector and the discharge or outlet end of the conduit. The novel water-escape device of the present invention is interposed in the water discharge conduit, at an exterior, above-ground location, to provide an emergency water outlet in the event that the downstream conduit segment becomes sealed against the free discharge of water therefrom.
