Woodford’s commercial roof hydrant provides a reliable, year-round water source. It features a heavy-duty cast-iron mounting system that can be installed by the roofer; the hydrant can be installed later. The freezeless hydrant automatically drains when shut off — even with a hose attached. Hydrants are backflow-protected with an ASSE 1052 double-check backflow preventer that is field- testable. The hydrant is easy to repair; all repairs can be made from the top of the unit without removing the hydrant.
