Dear friends,

 

In order to prevent back-flow in a series of fire water ring mains in a large industrial complex, I intend to use check valve on some branches. Meanwhile, I am looking for standard back-up. Has any one seen any objection in any standard/guideline against installation of check valves on fire water ring mains. I should add that NFPA-24, clause 6.5 allows installation of check valves under certain circumstances.

 

regards
