PRIER’s freezeless roof hydrant
By HPAC MagazinePlumbing freezeless rooftop hydrant
The new P-RH4 sanitary roof hydrant requires just a single penetration in the roof of 3-⅝-in.
The new freezeless roof hydrant from PRIER is designed with a piston-style displacement system. It requires no winterization or drain line, saving installation time, material, maintenance and labour cost.
The hydrant stores water in a canister instead of requiring a drain line like traditional roof hydrants, and its use of a piston system, rather than venturi, so it does not require winterization.
Roof hydrants have become more common on top of commercial facilities for cleaning air conditioning condenser coils, cooling towers and solar panels. There has also been a rise in rooftop gardens and green spaces requiring water. With a rooftop hydrant there is no need to pull heavy hoses up ladders which cuts down on potential injuries.
The new P-RH4 sanitary roof hydrant requires just a single penetration in the roof of 3⅝-in., and its sturdy bracket can be attached to concrete, wood or steel, I-beams, trusses, perlins or other structures with standard construction materials (Unistrut, threaded rods, or other).
It offers a high flow rate of 10 gallons per minute, bucket catch and lockable lever handle.
The roof hydrant is code approved to ASSE 1057 and NSF 372 lead-free standards.
