Nov 8, 2013 #4 Sdpaddler50 Mechanical Aug 30, 2012 200 Some will say an FM approval is more rigorous than UL. If you have a large client such as a Fortune 500 and they are insured by fm, they will want an fm approved pump. Upvote 0 Downvote

Nov 8, 2013 #6 SprinklerDesigner2 Mechanical Nov 30, 2006 1,251 The biggest issue I have found isn't so much the pump but the controller. FM will not approve a limited service controller but UL will. Upvote 0 Downvote
