Performance requirements in ASSE 1055 include compliance testing for stability; endurance; backpressure and backsiphonage; deterioration at temperature and pressure extremes; and detailed requirements for markings; and installation, operation, and maintenance instructions.
Geared towards 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.
The association elected John A. Parizek (Minnesota Chapter) as international president at the Business Session/Awards Ceremony of the 2018 ASSE International Annual Meeting.
