Excuse the typo of "lock a valve like this open", I meant closed obviously. Also the supervision of flowmeter valves is mentioned again in the "pump installation checklist" Mike Morey, SET, CFPS Sprinkler Designer BMW Constructors, Inc. O: 317.651.0596 | C: 317.586.8111 www.bmwc.com

The test outlet control valves shall be supervised closed. includes these valves, otherwise you could leave the meter bypass open and have no pressure. Typically we'd lock a valve like this open. One could argue that the test outlet control valve is defined as the test header control valve, but there's a checklist in the standard that makes mention that test header AND meter bypass valves need to be supervised (form S2.2).

Is there a general requirement that all valves in a pump room be supervised? I am wondering about the valves in a flow meter loop that are normally closed.
