Fire hydrant outlet ports must have at least how many inches clearance above grade?

Explanation:
Eighteen inches. This clearance keeps the hydrant outlet accessible for attaching hoses and fittings and prevents obstruction from grade, snow, landscaping, or parked vehicles. It also allows space to maneuver and connect the hose without the coupling or hose end hitting the ground. Six or twelve inches would be too tight for practical hose connection and operation, while twenty-four inches is more than typically required and can be unnecessarily intrusive on some sites.
