A fire hydrant repair tool is provided for removing a main valve of a fire hydrant, wherein the main valve has a pair of ring tabs extending upwardly therefrom. The fire hydrant repair tool can include a valve key having a first receptacle and a second receptacle that are configured to receive, respectively, the first and second ring tabs. Each of the first and second receptacles can define a first face that is configured to bias against the first side of a respective ring tab of the first and second ring tabs, and a second face that is configured to bias against the second side of a respective ring tab of the first and second ring tabs. A shaft can be coupled to the valve key.

A water-powered residential fire suppression and alarm system is provided. The system comprises a sprinkler head, a water-powered alarm, a fire-resistant transfer line assembly, and a housing assembly. The sprinkler activates upon excessive heat. The transfer line assembly provides an unclosable channel connecting an existing residential water fixture with the sprinkler head. The transfer line assembly includes a fire-resistant transfer line connected to a multi-port coupling which connects to the existing water fixture. The transfer line assembly also provides water to the alarm. The housing assembly has a housing with a vertical span of about 3-12 inches. The sprinkler head and alarm are mounted to the housing assembly and the transfer line assembly is connected to the housing assembly. When water is provided to the coupling and the sprinkler head activates, water flows through the transfer line, activating the alarm.

A mechanical joint includes a piping element, the piping element including an element flange, the piping element defining a socket extending inwards from the element flange; a pipe length, the pipe length extending through the element flange into the socket, the pipe length defining an outer pipe surface; and a gland, the pipe length extending through the gland, the gland including a joint restraint assembly, the joint restraint assembly including a restraint base; and a gripper disposed within the restraint pocket, the gripper configured to rotate in the restraint pocket, the gripper further configured to engage the outer pipe surface to prevent removal of the pipe length from the socket.
