Agree. However, this is similar to a fire pump test header control valve. The NFPA 20 committee thought it was important enough to supervise the fire pump test header valve. To me, this is a wasteful requirement but it is a requirement. We need this requirement changed.

Douglas, Search the archives for 'full forward flow test control valves'. lots of good stuff and fairly recent. brad -----Original Message----- From: Douglas Hicks [mailto:[email protected]] Sent: Monday, February 17, 2014 2:58 PM To: [email protected] Subject: Butterfly valve, monitered or not? I am going to install a 4" butterfly valve on a sprinkler manifold. This will give us an outlet to perform a Forward Flow. Does the valve need to be monitored or will it be OK to use a chain to lock the valve in the closed position? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
