2 SWAT protocols call for public comment

January 15, 2014 -  By

Smart Water Application Technologies (SWAT) released two revised testing protocols for public comment: Sprinkler Head Check Valves Version 2.1 and Spray Head Sprinkler Nozzles Performance Characteristics Version 3.0. Both  are open for public comment until Jan. 31.

Sprinkler Head Check Valves Version 2.1 specifies the test methods used to validate manufacturer claims for the sprinkler check valves, which reduce or eliminate draining of the piping system through heads located at the lowest elevation on a zone. The latest version of the test protocol is designed to measure how well the check valve operates and includes an endurance test that will indicate their long-term reliability.

The Spray Head Sprinkler Nozzles Performance Characteristics Version 3.0 now includes tests for all nozzles manufactured for spray head bodies whereas previous versions included only nozzles claiming to have higher efficiencies or higher uniformity. The revised testing protocol looks at how individual nozzles perform for flow and distance of throw over a variety of pressures, but it also measures how groups of nozzles work together in standardized configurations. The test results will provide an end-user with information to help select an appropriate nozzle to meet a specific landscape’s requirements. To review the protocol and submit comments, click here.
