Abstract: A system including a set rod with a first and second end, and a curved portion, in which the first end is to be placed against a clapper inside a check valve, and a first connecting nipple having a first end to thread into a ball drip outlet of the check valve and a second end to receive a rod locking component. The rod locking component has a first end to attach with the second end of the first connecting nipple, a second end, and a lock mechanism positioned in a center portion to positionally fix the set rod in its position while placed against the clapper inside of the check valve. The set rod traverses through the ball drip outlet into the first connecting nipple, through the first connecting nipple into the rod locking component, and egresses through the second end of the rod locking component.

Abstract: Systems, methods, and apparatuses for implementing in-situ configurable diffusion characteristics of mass water flows. For example, there is a water diffusion system permitting in-situ and field configurable diffusion characteristics of mass water flows for the purposes of testing, certification, water flushing, maintenance, and flame and heat management. According to such an embodiment, the rip-tide system includes a water diffusion box having a front inlet face configurable with one or more water inlets each configurable to connect with a water inlet pipe having a coupler to connect the inlet of the water diffuser box with a water source, and a rear plate via which to alter the water diffusion characteristics by the water diffusion box.

Abstract: Systems, methods, and apparatuses for mechanically securing a check valve in an open position during maintenance and testing operations.
