Currently I m working for Fire water pump replacement project at Offshore platform. In existing system,there is no annual flow test measuring facility. I want to know whether NFPA-20 calls for any mandatory arrangement for annual flow test? i.e. NFPA-20 (2016) Fig: A.4.21.1.2(a) & A.4.21.1.2(b) shows that the test measuring line tapping is taken between discharge check valve and isolation valve? Is this arrangement to be followed without any deviation? or the measuring line tapping can be taken from fire water main header with additional isolation valves in order to achieve 100% flow through test line?. Please confirm.

 

Regards,

Ramesh
