A fire hydrant is one of the most important parts of a water distribution system, but it's often one of the most
ignored. To ensured hydrants work correctly when they're needed, proper installation procedures must be followed.
The following recommendations are in accordance with ANSI/AWWA C600, STANDARD FOR INSTALLATION DRUCTILE IRON WATER MAINS AND THEIR APPURTANANCES.
1. Connect fire hydrants only to water mains adequately sized to handle fire flows.
2. Install the fire hydrants as plumb as possible.
3. Ensure hydrants are installed far enough away from the curb to avoid damage from or to turning vehicles. The recommended setback is 2-ft minimum from the face of the curb to the point on the hydrant nearest the curb.
4. The pumper outlet nozzle should face the street to enable a quick connection to the fire pumper.
5. Be sure the outlet nozzles are high enough (at least 18 in.) above the ground line to allow for attaching hoses and operating the hydrant wrench.
6. Always install an auxiliary valve between the hydrant and the supply main to isolate the hydrant for maintainance.
7. Provide trust restraint for the auxiliary valve so the Hydrant may be removed without shutting down the main.
8. Remove foreign matter from the hydrant before the installing the auxiliary valve hydrant.
9. In setting a hydrant, use a firm footing, such as stone slabs or a concrete baseon firm ground, to prevent settting and strain on the hydrant lead joints.
10. Provide for thrust restrainof the hydrant by strapping,blocking, or using a restraining-type joint.
