  • Publication number: 20110138527
    Abstract: A universal drain stopping device with enlarged stopper is installable in drains having different sized central threaded bores. A stopping assembly with a stopper and hollow shaft is removably engageable with a reversible stem. The stopping assembly and stem are axially reciprocable relative to each other when engaged. The reversible stem has opposite threaded ends having different sizes. The device is installable into a drain by threaded mating of one end of the stem with the central threaded bore of the drain. The stem can be axially reversed for installation into another drain with a different sized threaded bore. The stopper has a diameter that is greater than the outer diameter of the drain in which the device is installed.

  • Patent number: 7237280
    Abstract: An overflow assembly employs an overflow elbow having an externally threaded cylindrical fitting that extends through the tub overflow opening. An internally threaded retainer nut with integrally molded test cap is threadably engaged over the overflow elbow cylindrical fitting to compress gaskets against both the inside and outside surfaces of the tub. A test cap is integrally molded with the retainer nut and joined to the retainer nut by a thin, breakable connection. An undercut lip on the test cap facilitates use of a prying tool to break the thin connection and remove the test cap after testing of the drain plumbing. A trim cap snaps over the retainer nut to provide a finished appearance to the installed overflow assembly.

A compact design allows the control valve system to save space in the compact areas where plumbing fixtures are typically installed. The control valve system is constructed entirely of molded plastic components. Fittings supplied with the control valve system allow for customized installation according to the needs of the installer. Appliances may be easily added or removed using threaded connections on the valve and fittings supplied as part of the control valve system.
