I have an existing 12" waterline looped off of a 20" waterline and I am trying to set up an EPANET Model. We are trying to determine available fireflow / pressure in a new waterline that will loop from the 12" to the 20". A hydrant was recently flowed near the proposed tie-in on the existing 12"...
