摘要： A drain control assembly having a pop-up stopper controlled by a cam actuating mechanism allowing the stopper to alternately seal and unseat from the drain opening by pressing down on the stopper. Actuator guide rings extending from vertical fins and tabs are used to align and removably secure the actuator in position within the drain pipe. The stopper seal seats against the sink housing the drain providing a water tight seal. The assembly has a removable catch screen to retain items fallen into the drain. The stopper and actuator assembly can be dislodged and the entire assembly removed and items in the catch screen can be retrieved or the actuator removed for cleaning. The assembly can then be reinstalled by simply inserting it down into the drain.

摘要： A device used to conceal at least a portion of a wastewater strainer associated with a bathtub. More specifically, a plate having an opening therethrough is used to overlap a flange of the wastewater strainer wherein the opening in the plate generally coincides with an opening in the wastewater strainer so that the bathtub drain is unobstructed. The plate may include a downwardly extending lip to help facilitate orientation onto the flange of the wastewater strainer. The plate conceals the wastewater strainer, thereby facilitating reconfiguration of a bathtub as the existing wastewater strainer need not be removed and the plumbing system retested.

摘要： A drain stopper and strainer for a kitchen sink has a cap, a cap seal, an open-close mechanism, a strainer connected to a lower end of the open-close mechanism with an easy-connect mechanism, and an annular seal engaged with the strainer that seals an annular space between the strainer and a drain fitting. The cap seal preferably seals against the strainer. The stopper/strainer can be pushed into and pulled out of the drain fitting without assembly or disassembly. The strainer can be easily disconnected for cleaning and can be easily reconnected afterwards. For a drain fitted with a garbage disposal unit, the strainer has a hub-and-spoke structure for preventing eating and cooking utensils from falling into the garbage disposal unit.

摘要： The plug for a drain collects debris before the debris can enter the plumbing. The plug includes an outer rim; a conical core having a top cone end and a bottom core end opposite the top cone end; a cone cover being placed at the top cone end; and a plurality of cone ridges extending from the cone cover and toward the outer rim. The conical core has a conical surface with an inner side and an outer side opposite the inner side, a plurality of flow holes, and a plurality of strainer holes. Each cone ridge has a top cone ridge end larger than a bottom cone ridge end so as to form a collection ring portion on the conical surface. The conical core can have a plurality of protrusions extending outward. Debris can be collected by the protrusions at the strainer holes and at the collection ring.

摘要： The drain pipe cleaner plumbing tool is a set of tools that allow an individual to clean a clogged drain and to reduce the likelihood of future blockages. It comprises a cap to replace the retaining nut after the pivot rod and built-in stopper are removed from a sink, a tool that reaches into a drain line all the way to the wall and pulls out foreign material, a mesh drain liner that collects foreign objects near the drain hole where they can be easily removed, and a manual stopper that mates with the mesh drain liner.

摘要： A push-type drain stopper is usable in a drain pipe that has a pivot rod port surrounded by a stub by sealing a rod that protrudes into the pipe through the stub. The stopper is pressed transversely into engagement with the rod, which is an anchor. The drain pipe has a drain flange that seals around a drain opening in a sink. If the flange becomes worn and unsightly or if one desires to change a color scheme for the sink, a cap that has a diameter greater than the drain flange hides the drain flange from sight. A retrofit kit includes the drain stopper, pivot balls sized to fit different pop-up drain assemblies, a rod that passes through the ball into the drain pipe, and a wing nut fixed to an end of the rod for tightening the rod against a stub cap.
