Project location: Bangladesh
Pump Capacity: 1500 GPM
Pump Head: 14 bar.
According to code for sprinkler pressure should not exceed 12 bar. So we need to use PRV upto certain height. If each PRV require to use by pass system , we also need to use valve and does that valve need to be supervised?
Could anyone please suggest regarding this as per NFPA?
Thanks In advance.
