Abstract
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 fire hydrant repair tool for removing a main valve of a fire hydrant, the main valve having a central rotational axis, the fire hydrant repair tool comprising:
- a valve key comprising:
- a first face that is configured to bias against a first upwardly projecting surface of the main valve to effect rotation of the main valve in a first direction around the central rotational axis;
- and
- a second face that is configured to bias against a second upwardly projecting surface of the main valve to effect rotation of the main valve in a second direction, opposite the first direction, around the central rotational axis.
A method comprising:
- providing a valve key that defines:
- a first face that is configured to bias against a first upwardly projecting surface of a main valve to effect rotation of the main valve in a first direction around the central rotational axis;
- and
- a second face that is configured to bias against a second upwardly projecting surface of the main valve to effect rotation of the main valve in a second direction, opposite the first direction, around the central rotational axis;
- and
- lowering the valve key into the fire hydrant until the first face extends past the first upwardly protecting surface along the central rotational axis.
A kit comprising:
- a plurality of valve keys, each valve key configured to engage a respective particular fire hydrant main valve, each valve key comprising:
- a first face that is configured to bias against a first upwardly projecting surface of the respective particular main valve to effect rotation of the main valve in a first direction around the central rotational axis;
- and
- a second face that is configured to bias against a second upwardly projecting surface of the respective particular main valve to effect rotation of the main valve in a second direction, opposite the first direction, around the central rotational axis.
