    Hypothetical situation. Say you have an area 40' x 160' with 50 psi. What would you use and spacing? 40' is too far for residential rotors with this psi, too far for 2 lines of MP2000's.

    I wouldn't use anything until I got more information.

    Let's just say you are working with about 15 available gpm & 50 psi. You're not going to get a rotor to reliable throw 40' so would you space MP3000's 20 feet apart and throttle them down.

    Still got nothing man. 15 GPM @ 50 PSI where .... POC, valves, nozzle ... Is that a static PSI or dynamic? Why do you think you can't get 40 feet out of a resi-comm rotor?
     
  6. I'd use three lines of MP2000s in triangular spacing if that is your choice of head. Maxi paws rule in these types of situations though.

    I find it difficult to actually get 20' out of a MP2000. Can you actually get 20' without ALOT of extra pressure?

    This is all hypothetical. Let's say 50 static after the backflow. Assume you have approx 15gpm per zone to work with. I realize you can get 40' out of a head but the larger size nozzle required would mean putting very few heads on a station which would mean I would have an excessive # of stations.

    What head/nozzle would you use to throw 40' or would you divide it into 2 and throw 20'?

    20' would be a stretch with minium psi.

    yes

    Hypothetically speaking, without an estimated nozzle pressure you have nothing here. Hypothetically if I could assume 40-45 psi at the nozzle I would be using RB5000 series with a #4 nozzle on the 180's.
