| 20080196775 | VALVE FLAP FOR A PLUMBING VALVE - A valve flap for a plumbing valve, includes a body having a first face, a second face, a top and a bottom. A pivotal mounting is provided in the vicinity of the top. A curved lower snake deflecting contact face is provided in the vicinity of the bottom, adapted to facilitate sliding contact with a plumbing snake. This valve flap enables a plumbing snake to be inserted into and withdrawn from the plumbing valve. | 08-21-2008 |
| 20090095357 | BACKWATER VALVE ASSEMBLY WITH REMOVABLE VALVE MEMBER - A backwater valve assembly includes a valve housing, a valve member and a servicing tool. The valve housing has an internal ledge within its interior on which is positioned a retainer clip oriented in vertical alignment with a riser. The valve member has a first engagement of a two part engagement on one face and a mounting along a peripheral edge which includes transverse pins adapted to engage the retainer clip. The servicing tool includes a second engagement of the two part engagement at a working end of a shaft. The hook engages the hook receiver of the valve member during insertion and removal. | 04-16-2009 |
| 20090272930 | RESILIENT TEST VALVE MEMBER - A method and apparatus for pressure testing a plumbing system, includes a resilient body having a body diameter. The resilient body is adapted to elastically deform by when passing through a service opening that is smaller than the body diameter and then resiliently return to the body diameter. A sealing surface is carried by the resilient body. A rigid coupling is positioned on the resilient body. The rigid coupling is adapted for coupling the resilient body to a shaft, such that the shaft is able to manipulate movement of the resilient body. The resilient body is inserted into a service opening of a plumbing system to be pressure tested. The resilient body flexes while being inserted and then resiliently returns to the body diameter with the sealing surface performing a sealing function. | 11-05-2009 |
| 20090295101 | SEAL FOR PRESSURE TESTING A PLUMBING INSTALLATION AND METHOD OF USE THEREOF - A method for testing the integrity of a plumbing system. A first step involves affixing a seal with a releasable adhesive over a component of the plumbing system having a bore to occlude the bore. A second step involves charging the plumbing system with a fluid. | 12-03-2009 |
| 20100012211 | TEAR OUT TEST PLUG FOR PLUMBING INSTALLATIONS - A tear out test plug for plumbing installations includes a cylindrical body having a peripheral sidewall, a closed end and an open end. A positioning flange extends outwardly from the peripheral sidewall at the open end. An end wall closes the closed end. A frangible strip extends from the open end, down the peripheral sidewall, and across at least a portion of the end wall. | 01-21-2010 |
| 20100012212 | APPARATUS FOR PRESSURE TESTING A PLUMBING INSTALLATION - An apparatus for pressure testing a plumbing installation includes a flexible cylindrical body having a peripheral sidewall, a closed end and an open end. A positioning flange extends outwardly from the peripheral sidewall at the open end to facilitate positioning cylindrical body with an end of a pipe into which the cylindrical body has been inserted. An end wall is positioned at the closed end that is. The end wall is curved inwardly and has an inward cylindrical flow channel closed by a partially removable plug. A gripping strip is secured to the partially removable plug that closes an inward cylindrical plug and extends through and past the open end of the cylindrical body, such that upon a force being exerting upon the gripping strip the plug lifts to open the cylindrical flow channel and upon a force continuing to be exerted upon the gripping strip the cylindrical body rolls inside out thereby enabling the cylindrical body to be removed from the pipe. | 01-21-2010 |
| 20100078083 | LOW PROFILE BACKWATER VALVE - A low profile backwater valve includes a hollow valve body having an inlet, an outlet, and a bottom. A pivoting valve member is pivotally movable between a normally open position along the bottom of the valve body and a closed position sealing the inlet. The valve member has a hinge end, a remote end, and opposed sides. A float is positioned as an appendage along at least one of the opposed sides of the valve member, such that the float adds buoyancy to the valve member causing the valve member to float into the closed position in the presence of a backflow. | 04-01-2010 |
| 20100229989 | PLUG WITH ENGAGEMENT MEMBERS - A plug has a plug body having an upper face and a lower face and a deformable member having opposed pipe engagement ends. A support structure is carried by the plug body and spaced from the lower face. The support structure supports the opposed pipe engagement ends of the deformable member. An actuator extends outward from the lower face of the plug body and is connected to the deformable member. The actuator adjusts the distance of a central portion of the deformable member from the lower face of the plug body to cause the engagement ends to move between a retracted release position and an extended engagement position. The actuator is actuated from the upper face of the plug body. | 09-16-2010 |
| 20100306954 | DUCT CLEANING ATTACHMENT FOR A VACUUM - A duct cleaning attachment includes a hollow body having an exterior surface with a curved under-belly, one of a tapered or rounded leading end, a trailing end, and an interior surface defining an interior cavity. A coupling is positioned at the trailing end wherein the body is coupled to a hose from a vacuum source in a manner that results in air being drawn from the interior cavity by the vacuum source. The body has openings from the exterior surface to the interior surface. | 12-09-2010 |
| 20110120924 | DRAIN COVER WITH LOCKING MECHANISM - A drain cover with a locking mechanism which has a cylindrical body with a first end, a second end, an end wall at the first end and a peripheral sidewall that extends between the first end and the second end. The peripheral sidewall has an exterior surface and an interior surface which defines an interior bore. A wedge member positioned at the second end of the peripheral sidewall and is movable from a release position to a locking position. In the release position each wedge member is positioned at the second end of the peripheral sidewall. In the locking position each wedge member is moved up the exterior surface of the peripheral sidewall toward the first end. Means are provided for moving each wedge member from the release position to the locking position. | 05-26-2011 |
