The Flex924 complete bath waste helps with misalignment between bathtub overflow and drain connection. This product has PVC tubing that connects the overflow to the sanitary tee of the bathtub, and it bends to accommodate misalignment and eliminates the need for offsets. It ships with a factory-installed test membrane at the overflow and test plug for the drain that is testable up to five floors. The snap-on, Innovator overflow plate requires no screws.
