An apparatus includes a blowout preventer housing including a bore extending therethrough and a cavity intersecting the bore. The apparatus further includes grooves in the outer profile of the blowout preventer housing, the grooves being on opposite sides of the cavity.

A valve flush apparatus includes a rigid base designed to removably attach to a body of an irrigation valve. A stem extends outwardly from the base and away from the body of the irrigation valve and may be centrally located on the base. The stem and an aperture in the base may define a water passageway through which water may flow through the body of the irrigation valve and through the valve flush apparatus. A hose may also be included which removably attaches to the stem so as to extend the water passageway of the valve flush apparatus. A method includes flushing a clogged irrigation valve through use of the valve flush apparatus.

Valve and related assemblies, systems, and methods may include a self-cleaning feature that may be configured to at least partially displace material from a portion of the valve. Such valves may be utilized in a pressure exchanger.

A faucet valve cartridge pulling tool comprising a housing, a stem screw, and a collar. The housing has a first end and a second end. The first end has a surface adapted to abut a portion of a faucet valve body. The stem screw has a first end and a second end. The stem screw includes a first threaded section and a second threaded section. The first threaded section is adapted to engage internal threading of a faucet valve cartridge stem located within the faucet valve body. The collar has internal threading engaging the second threaded section of the stem screw. Wherein, rotating the collar relative to the stem screw pulls the first threaded portion axially towards the second end of the housing.

A kit comprising an adapter, having a slip end and a reverse-threaded end, and a pipe nipple having standard threads on one end and reversed threads on the other end. And the kit has PVC or other pipe cement, fittings with standard slip threaded connections blades, saws, cutters, or other irrigation pipe cutters, and valves, among other components.

A method for repairing a valve manifold with the steps of cutting a pipe system near a broken component (such as a valve); connecting a slip end of an adapter having a slip end and a reverse-threaded end to the system (sometimes gluing the connection with cement); removing the broken component from the system; attaching a replacement for the broken component; supplying a pipe nipple having a threaded end and a reverse-threaded end; inserting the pipe nipple into the normal threaded end and the reverse-threaded end; and tightening the pipe nipple to yield sealed joints.
