A check valve includes a valve body defining a valve bore extending from a first axial end to a second axial end, the valve body including an annular body and a cross member secured to and extending across the valve bore from the annular body on one side of the valve body to the annular body on an opposite side of the valve body, the valve bore at the cross member divided into more than one portion by the cross member; a position block extending from the cross member; a valve member positioned within the valve body and configured to rotate between an open position and a closed position; and a pivot pin extending from the valve member, engaged with the position block, and fixed with respect to the valve member; the valve member and the pivot pin configured to rotate together between the open position and the closed position.

A hydrant includes: a hydrant body defining a hydrant inner cavity, the hydrant configured to couple to and be in fluid communication with a fluid distribution system including a fluid therein under pressure; and a break check valve coupled to the hydrant body, the valve including: a valve body defining a valve inner cavity, the hydrant inner cavity defining a valve bore in fluid communication with the fluid during normal operation of the hydrant; a valve member configured to rotate from an open position to a closed position of the valve; and an arm in contact with the hydrant and configured to prevent movement of the valve member when the hydrant is coupled to the valve, the valve defining a hole separate from the valve bore and in fluid communication with each of the hydrant inner cavity and the valve inner cavity.

A wrench for securing, actuating and preventing tampering with a fire hydrant is disclosed. In useful embodiments, the wrench can be a two-ended wrench having a loop that encloses a pentagonal opening at either end of an elongated handle, where the handle can include in a nonterminal portion a slot. In a locking mode, the wrench can accept at a first end an actuating nut of the fire hydrant and can be locked in place by inserting a locking arm of a padlock through an eye bolt that is secured to a side of the fire hydrant and inserted through the slot. The wrench can be unlocked and removed, whereupon a second end can be used to turn the actuating nut as well as to remove water outlet caps and adjust nozzles.

Example aspects of a nozzle cap for a fire hydrant and a method of detecting a leak in a fluid system are disclosed. The nozzle cap for a fire hydrant can include an outer housing defining a first end, a second end opposite the first end, and a substantially circumferential wall extending from the first end to the second end; an antenna coupled to the substantially circumferential wall of the outer housing; a cap cover coupled to the outer housing at the first end; and an inner housing coupled to the outer housing at the second end.
