i'm working on a shopping center with 3 separate p.o.c.'s. we are on like the 10th set of revisions, any way toi sum it up, when i first started working on this set of revsions, and changed the area for dripline, i would just move the area around, use tool for moving piped equip for the fittings and transition points, re=pipe what i had to and it was all good. than last night i go to move around some more stuff, same process and now i can't size the pipe in the drip valves b/c something is causing it to like over a 1000 gpm. how would that have happened?
