We wish to utilize a Trapeze hanger to support more than one pipe, and have calculated the required weight of the water-filled pipe for all loads. We then added 250 Lbs. for additional load.
Is it the intent of NFPA 13 (2016) chapter 9 that we include an additional 250 Lb. for each pipe to be supported along the Trapeze, or only the one-time inclusion of the additional 250 Lb. for the Trapeze assembly?
