We work in a jurisdiction that requires these on all fire pump installation,  
they are installed on the discharge before the check valve and the there is a 
sensing line piped back to the suction side of the pump, usually into the OS&Y 
½" plug with copper or brass.

It is required to be an OS&Y and located between the suction flange and the 
fire pump bypass.  No preference on manufacturer other than complying with the 
specifications.

Subject: [Sprinklerforum] Suction Control Valve

I have to put a suction control valve on a fire pump for the first time. I'm 
assuming it goes on the suction side of the pump. Does it go before or after 
the RPZ backflow? Anyone have any preferences as to brand or model; this one is 
an 8". First time in 45 years of doing this.
