An overflow pipe assembly includes an overflow pipe having an end portion. An adaptor is connected to the end portion of the overflow pipe and includes a first connection portion formed to the center thereof. A second connection portion which is a slot, and a third connection portion which is a bore, are respectively formed to two ends of the adaptor. A cover includes multiple protrusions which are engaged with the engaging portions of the adaptor to connect the cover to the adaptor. When installing the adaptor to an overflow pipe with two tubular parts, the adaptor does not shift by extending bolts through the second and third connection portions and connected to the two tubular parts. When installing the adaptor to an overflow pipe with a single tube, a bolt extends through the first connection portion and is connected to the tube.

A bathtub overflow assembly comprises a holder and a faceplate that attaches to the holder using a snap-fit or threaded connection. The holder has rectangular shape, a length greater than the diameter of a bathtub overflow port and pass-through screw holes for attachment to an overflow fitting. The holder has a pair of posts that project from an outer surface, and each post has a shoulder near a distal end for the snap-fit connection. The faceplate has walls that project from an inner surface, and the walls have openings for receiving the shoulders for the snap-fit connection. The holder is attached to the overflow fitting using one or more screws, and the faceplate is pressed into engagement with the holder for the snap-fit connection. For the threaded connection, the holder has a central threaded tube, and the faceplate has a threaded element that engages the tube by rotating the faceplate.

A sink strainer assembly for attachment to a clamping ring of a sink waste valve assembly comprising a strainer sized to fit within and be attachable to the clamping ring by a locking bar attachable to the clamping ring and at least one or more screws affixing the strainer to the locking bar, the improvement to which comprises (a) the strainer comprising a cylindrical body having top and bottom surfaces provided with passageways extending from the top surface and extending through the bottom surface to permit fluids to pass through the strainer, a channel cut in the bottom surface and having a post cavity of greater depth than the channel, a screw passageway extending from the bottom of the post cavity through the top surface of the strainer body; (b) the locking bar comprising an elongated slat member having a width greater than the depth of the channel and a length sized to fit in the channel, the slat having a post member sized to fit into the post cavity, the post member having an axial passageway formed by a threaded interior wall and positioned on the slat member to be aligned to the screw passageway when the locking bar is positioned in the channel, the slat having its opposing end sections forming a shoulder extendable beneath the clamping ring lower rim when the strainer is positioned in the clamping ring; and (c) a screw sized and shaped to fit into the screw passageway and be operatively engaged with the threaded interior wall of the post member.

A self-sealing drain vent cover that allows for a vacuum to be created within piping of a plumbing fixture for unclogging purposes. The vent cover includes a outer cover and a seal insert. The outer cover includes a first tubular body and a first disk top to yield a closed off structure to support the seal insert. The first disk top is terminally and perimetrically connected to the first tubular body. The seal insert adheres to a surface around an overflow port to enclose said port. The seal insert includes a second tubular body, a second disk top, and an annular self-sealing mechanism. The second disk top is terminally and perimetrically connected to the second tubular body. The seal insert is mounted within the outer cover. The self-sealing mechanism is positioned adjacent to a bottom end of the second tubular body and is concentrically mounted to the second tubular body.

An overflow system for concealing an overflow conduit of a bathtub includes a nut and a cover. The nut has an inner mount configured to secure to the conduit that is substantially circular in shape, and an outer mount including a plurality of engagement sections that extend substantially tangential to the inner mount. The inner mount has a thickness that is greater than a thickness of the outer mount, and the outer mount is centered on and integral with the inner mount. The cover is configured to couple to the nut and is substantially square. The cover includes a front wall and a plurality of side walls, each having a first end extending from the front wall and an opposite second end. The second end includes a lip configured to engage with a respective engagement section of the plurality of engagement sections when the cover is coupled to the nut.

A tub drain overflow test system employs a kit with a connecting pipe with a front cylindrical portion having an inner threading and an intermediate annular flange coaxial with the front cylindrical portion. The front cylindrical portion extends through an overflow hole of a tub so that the annular flange, optionally with a seal ring, abuts the rear surface of the tub wall. A test cap has outer threading that mates with inner threading of the front cylindrical portion. The test cap has an annular flange and a breakaway test seal with a projecting grip tab. The test cap has an inner lip that provides a catch for inwardly extending tabs on a fixture to attach. The test cap allows the overflow drain to be tested. A seal portion is removed to provide access to the opening and the finishing fixture is mounted in place.
