Hello all! I am new to the forum here but have been following for quite some time. I am currently in the process of updating my existing irrigation system from Hunter PGP ultra rotors to MP rotators. The main issue I seem to be having is system pressure. I have read through quite a bit of the irrigation tutorials website but still can't seem to figure out my issue. My home provides 11gpm @ 50psi. However every single rotor zone seems to only operate @ 20psi. While 20psi is low for the MP rotators the 3000s seem to work fine in the front lawn where my heads are only spaced @ 20ft. I am however 2nd guessing the swap in my backyard as the heads are spaced closer to 25-30ft. My main question is what in the world could be eating up 30psi from the source to the heads? I would prefer to operate these at their recommended 40psi. Any help would be greatly appreciated!
