A fire hydrant barrel includes a body having at least one wall and an anti-rotation pin opening through the at least one wall. The at least one wall defines an internal cavity. The fire hydrant barrel also includes a stem extending through the cavity of the body. The stem has an anti-rotation element, and the anti-rotation pin opening and the anti-rotation element are configured to receive an anti-rotation pin to lock the stem from rotating with respect to the body.

A freeze resistant sanitary hydrant is provided that employs a reservoir for storage of fluid under the frost line or in an area not prone to freezing. To evacuate this reservoir, a means for altering pressure is provided that is able to function in hydrant systems that employ a vacuum breaker.

A fire hydrant assembly for use with an irrigation riser stub may include a generally cylindrically-shaped main body having an open end and a closed end. The open end of the main body has an inside diameter that is sized to slidably receive an end portion of the irrigation riser stub. A seal disposed within the open end of the main body is sized to sealingly engage the irrigation riser stub. A nipple having a threaded end and a plain end is mounted within an opening provided in a side portion of the main body so that the threaded end may be threaded onto a fire hose assembly. An actuator shaft extends through a shaft opening defined by the closed end of the main body so that a head end of the actuator shaft is disposed outside the main body and so that a distal end of the actuator shaft is disposed within an interior cavity defined by the main body. A yoke mounted to the distal end of the actuator shaft is sized to operatively engage a valve stem associated with the irrigation riser stub.

A sensing device for a hydrant can include a sensor located entirely within an interior cavity of a hydrant body of the hydrant and configured to measure a property of a fluid of a fluid distribution system and an antenna in communication with the sensor and positioned within the interior cavity.

A method of manufacturing a main valve of a hydrant includes: forming an internal rigid structure including a top surface, a bottom surface, a side surface, and a locating feature, the locating feature defined in a one of the top surface and the bottom surface; positioning the internal rigid structure in a mold by contacting the locating feature with the mold; and forming an outer shell around the internal rigid structure.

Breaker straps, preferably made of steel, include holes that line up with the holes in breaker rings, to keep the breaker rings in place on a fire hydrant. A collision kit includes breaker straps, the breaker rings, a coupling, and coupling pins.
