§ A144-14. Setting of hydrants.

Hydrants shall be set exactly plumb and to the depth intended by the manufacturer. They shall rest upon a selected stone or block of concrete not less than 12 inches by 12 inches by six inches, cushioned by a few inches of sand, and shall be similarly backed up to prevent the likelihood of a joint's blowing out. Hydrants shall be surrounded by at least five cubic feet of one-and-one-half-inch crushed stone gravel. In excavations where drainage cannot be secured in this way, other arrangements for drainage will be made. Each hydrant shall be placed on a six-inch spur connection with the main and shall be provided with an individual mechanical joint shutoff valve. Just prior to the completion of the job, all hydrants shall be painted with one coat of an approved paint. All hydrants shall be anchored according to AWWA standard (Section 12).
