I've just converted one of my one man systems to a two man system but i'm having problems. Here is the set up. hose from water tank goes into a y shaped adapter one branching to one pump one to the other, then seperate hose coming out from the outlet on the pumps throught two seperate di vessels then finally to hoses to two seperate hose reels, both pumps are controlled by digital flow controllers. The problem is there doesn't seem to be any water coming through the hose reel. Will the y adapter cause issues if i have one pump on and the other of i can't seem to figure out why i'm not getting any pressure, anyone any ideas.
