This commercial roof hydrant provides a reliable, year-round rooftop water source, Woodford notes. It features a heavy-duty cast-iron mounting system. 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. Repairs can be made from the top of the unit without removing the hydrant. www.wcmind.com
