Bridge-Mounted Dry Hydrant Installation Coverage - Gamber, MD
 
By President Mark Davis
December 4, 2015
 

We installed a bridge-mounted dry fire hydrant today on a bridge in Gamber, Maryland. The DFH used our swivel-mount design that allows the pipe to be stowed out of the water until needed. The design has become popular because it does not interfere with wetlands or streambed environs - and the pipe and strainer are protected during periods of high water. Today's installation used a 6-inch Kochek suction head and tear drop strainer (shallow water). The installation will be complete once a flow test is done (after the 24-hour glue curing process) and the pipe is painted with UV-resistant paint (on a warmer day).
