The combination of: an underground valve for a supply line and having an underground actuator through which a state of the valve can be changed to control flow within the supply line; and a conduit assembly embedded in ground material and defining an access passage through which above ground access can be obtained to the valve actuator. The conduit assembly has an adaptor assembly with a body made from a non-metal material and having at least a first connector. The valve has at least a second connector. The first and second connectors cooperate to maintain the body operatively connected to the valve. A first conduit part is configured to connect to the body and bound a portion of the access passage accessible through an entry opening remote from the valve.

The combination of an underground valve, for a supply line and having an underground actuator through which a state of the valve can be changed to control flow within the supply line, and a conduit assembly defining an access passage through which above ground access can be gained to the valve actuator. The conduit assembly further has a cap that can be selectively changed between: a) a first state wherein the cap blocks an entry opening; and b) a second state wherein above ground access can be gained to the valve actuator through the entry opening and access passage. A part of the cap and another part of the conduit assembly interact and are relatively moved as the cap is changed between the first and second states. At least one of: a) the part of the cap; and b) the another part of the conduit assembly is made from a non-metal material.

In some implementations, an apparatus includes a container having an exterior surface, having an interior surface and having a defect, a gasket positioned over the defect in the container, the gasket having a length, a width and a depth, a rigid patch positioned over the gasket, a plurality of pairs of studs and nuts positioned near the outer perimeter of the rigid patch, the studs being friction welded to the exterior of the container.

A rigid piston assembly for use in a conventional flush valve includes a rigid piston and a solenoid configured to fixedly engage within the valve body. A flush valve for a plumbing fixture as well as a method of retrofitting a piston valve into a diaphragm flush valve body which includes a rigid piston and solenoid configuration.

The present invention is also directed to a flush valve for a plumbing fixture as well as a method of retrofitting a rigid piston into a diaphragm flush valve body.

The combination of: a) an underground valve for a supply line and having an underground actuator through which the state of the valve can be changed to control flow within the supply line; and b) a conduit assembly embedded in ground material and defining an access passage through which above ground access can be obtained to the valve actuator. The conduit assembly has a cap that can be selectively changed between: a) a first state wherein the cap blocks the entry opening; and b) a second state wherein above ground access can be gained to the valve actuator. The conduit assembly has an upper conduit part and a lower conduit part. The upper and lower conduit parts are interconnected and configured so that they move axially guidingly against and relative to each other so as to vary an effective combined axial length of the upper and lower conduit parts in response to forces generated by the ground material.

A method of repairing an existing conduit assembly embedded in ground material. The conduit assembly has an axial length and defines an access passage through which above ground access can be obtained to an underground valve actuator. The method includes the steps of: removing a portion of the length of the conduit assembly to expose an upper edge defined by a remaining portion of the conduit assembly; providing a repair assembly with a conduit piece having an entry opening; engaging the conduit piece and the remaining portion of the conduit assembly; moving the conduit piece guidingly in an axial direction against the remaining portion of the conduit assembly to thereby situate the entry opening at a desired axial location; and placing a cap on the conduit piece to thereby block the entry opening.

In some implementations, an injection system that injects sealant into a pipe, pressure component or valve while containing the pipe, pressure component or valve repair that significantly reduces or eliminates release of hazardous material from inside the pipe, pressure component valve or injection system and thus significantly reduces emission of the hazardous material from inside the pipe, pressure component or valve into the environment and protecting the repair technicians.

Methods and apparatus to access and align sealing discs are disclosed herein. An example apparatus includes a cage of a fluid regulator, where the cage has a central aperture, and a valve stem to be received by the central aperture. The example apparatus also includes a diaphragm coupled to the valve stem, where an integral protrusion of the cage is to constrain a peripheral edge of the diaphragm against a removable portion of a valve body when the cage is coupled to the valve body.
