NFPA20 Fire Pump Suction

Question asked by phil.smith on Oct 11, 2018

Hi guys, designing an NFPA 20 Pump set & limited on space. If I apply the A.4.14.6 Ruling and install my suction line vertically (Keeping the distance between pump flange and elbow tee flange greater than 10 Pipe Dia) will this have any impact on my Water storage tank effective capacity? With the suction line being elevated, does this effect this at all, or is there any considerations/Rules that apply when we use a vertical suction line? 

Your help is appreciated
