Embodiments relate to a leak detection device. In some embodiments, the leak detection device can be used within a backflow preventer to detect faulty or degraded operation of the backflow preventer or plumbing system instability. Embodiments of the leak detection device can include a movable magnetic element and a reed switch or electrical conductor element. When a leak occurs, fluid causes the movable magnetic element to move relative to the reed switch or electrical conductor element and cause the reed switch or electrical conductor element to generate a signal.

Ball valve retainer with soldering paste seal and method
A method of sealing a metal retainer to a metal valve body that includes the steps of applying a soldering paste in a predetermined amount to the threads of a threaded retainer and threading the retainer into the threads of a threaded opening in the valve. The retainer is heated to a temperature sufficient to liquefy and disperse the soldering paste into spaces between the threads of the retainer and the threads of the opening in the valve to thereby achieve an adhesive seal.

ABSTRACT OF THE DISCLOSURE A spill-resistant vacuum breaker valve that includes a check assembly positioned in a valve body and is movable between an open position for allowing water to flow into the valve body through the water inlet and out of the valve body through the water outlet, and a closed position for preventing water from flowing out of the valve body through the water outlet. The check assembly cooperates with a float assembly movable by movement of the check assembly between an open position allowing air to enter the valve body through the air inlet and a closed position sealing the valve body against flow= of air into the valve body through the air inlet. The float assembly is adapted to pivot sufficiently to level the float and seal against ejection of water from the valve in the event of non-axial movement of the check assembly in the valve body.
