In December 2021, we completed the repair of a leaking dry fire hydrant in Harford County, Maryland. The head was on a rather interesting installation at an old marble quarry. The defective head was a swiveling type and was leaking at the swivel. A new, fixed-position head (ETT 6-inch female) was installed and positioned a bit on an angle so that a pumper could better position and reach the connection using the driver side suction inlet. The dry fire hydrant system was designed to anchor to the side wall of the idle quarry. Water quality was great and water quantity incredibly large.
