Q:  How often should large and critical valves be exercised?

A:  Some manufacturers recommend six months while others recommend annually.  The AWWA’s M44 Manual, Distribution Valves:  Selection, Installation, Field Testing and Maintenance, Third Edition, recommends that valves deemed critical are inspected and exercised on an annual basis, and other less critical valves in the system should be inspected and exercised based on the level of service established by the agency.
