    摘要： A drain assembly including a drain pipe with a threaded portion and a nut is provided. The drain pipe includes a first end, an elbow portion, and a second end. The first end includes an annular flange and the threaded portion. To interconnect the drain assembly to a bathtub, the second end of the drain pipe is inserted through a drain port of the tub until the annular flange abuts a bottom wall of the tub. The nut is then threaded onto the threaded portion of the drain pipe to secure the drain pipe to the bathtub. The second end of the drain pipe is then interconnected to drain plumbing.

    摘要： A double check valve is provided that includes an in-line inlet check valve and an outlet check valve that cooperate to prevent back flow of fluid through the valve. The check valve also includes at least one vent that allows for fluid trapped within the check valve to drain, thereby preventing freezing of the check valve and hydrant to which it is interconnected. The check valve provided omits many superfluous components and thus is smaller and easier to install than check valves of the prior art.
