PRIER's P-RH1 Flush Mount Roof Hydrant provides a year round source of water to roof surfaces in areas with freezing temperatures, making rooftop and equipment cleaning and maintenance a breeze. The hydrant is installed flush to the roof, allowing the hose to run in 360°. The hydrant valve is connected to the supply piping below the freeze line, and is self-draining, eliminating the possibility of freezing. A removable operating key is provided to prevent unauthorized usage of the hydrant.

The P-RH1 attaches to any roof structure by means of PRIER's new Universal Roof Hydrant Mounting Bracket (P-RMB). In contrast to competitors' options, PRIER's mounting bracket attaches to the structural member of the building with rigid support, instead of the skin of the building like competitive products. Additionally, the P-RMB requires only a single penetration point and is adjustable to accommodate roof angles. This bracket can be mounted to concrete, wood, steel, I-beams, truss, perlins or other structural member with standard construction materials (Unistrut, all-thread, etc.).
