Geared toward engineers, architects, specifiers, and facility managers, this webinar will cover why a reduced pressure zone (RPZ) relief valve may open — and how to prevent and mitigate large discharges of water. It will be presented on Feb. 26 by Cameron Rapoport, product specialist for backflow at Watts.
