The IA, an organization for irrigation companies and professionals, has announced an open public comment period for Smart Water Application Technologies released Sprinkler Head Check Valve Testing Protocol Version 2.2.

The Irrigation Association has announced an open public comment period for Smart Water Application Technologies released Sprinkler Head Check Valve Testing Protocol Version 2.2. The protocol is open for a 30-day public comment period, with feedback due April 30.

The check valve testing protocol specifies the performance requirements and test methods for sprinkler head check valves intended for operation in irrigation systems. Industry stakeholders were invited to submit public comments to version 2.1 of the protocol last December.

Based on the feedback received, SWAT has revised the document to include an additional test that measures the performance of the check valve when placed at 15-, 30- and 45-degree angles (see Annex A, A.9). In addition to tests of the sprinkler in a perpendicular orientation, the added test will determine how the check valves perform when used on sloped landscapes in a tilted position.

Public comment forms are available on SWAT's website. Review the latest protocol and submit completed forms to iaswat@irrigation.org. For more information about SWAT and the Irrigation Association's standard initiatives, contact IA Industry Development Director Brent Mecham, CID, CLWM, CIC, CAIS.
