ABSTRACT:
The drain assembly is constructed with a segmented ball valve of stainless steel or plastic which is rotatable between an open position and a closed position by a shaft extending from the drain body. An annular valve seat is biased against the valve body by a compression device and an annual retainer which is threaded into the valve body from above. A strainer may also be provided to catch large particles which might otherwise not be desirable for passage through the drain assembly. The valve body provides a relatively large opening for the discharge of fluids into a drain pipe.
