Abstract:

A bathtub overflow assembly having an overflow elbow exterior to the bathtub's overflow port with an externally threaded cylinder extending axially from the overflow elbow in the direction of the overflow port. The assembly has an overflow elbow retaining structure in the tub comprising a retainer ring having a flange sized to circumscribe the overflow port on the interior of the tub. The retainer ring has a centrally mounted sleeve which extends axially in the direction of the elbow. The sleeve is internally threaded to cooperatively engage the threads on the overflow elbow cylinder and has a length which is sufficient to enable it to overlap the overflow cylinder. An overflow test plug which threadedly mounts to the retainer ring is also disclosed.
