    Which do you guys perfer and why?

    Lets talk:

    Uniformity

    Run times

    Slopes

    Coverage

    How far each nozzle really throws effectively
     
  2. If the angles work I'd take the RB rotators in a heartbeat. If you have to use a multistream and need oddball angles then the MPs would be my choice but only for design reasons.

    I have the mp2000's in my yard.

    23 or 24 of them.

    I placed them at head to head coverage. Run times are 20 minutes on 2 zones and 15 on the other. Due to heat stress. I water daily and need to hook up my rain sensor. 4th zone is drip lines.

    Uniformity is ridiculously good. I went over kill. I could of gotten by with several less heads. I only have around 4000 sq ft of grass. I did placement at every 17 or 18 feet. Forgot off hand.

    I did not use the mp40 pop ups. I had to use a pressure reducer in my valve box. I had roughly 100 - 110 psi of water pressure. Which created horrible streams. I initially cut the pressure back to about 50 psi, and im using 1" pipe throughout the system. After evaluating the pattern and streams, I raised the pressure to fine tune the stream, ended up being 55-60 psi.

    I'm sure the 2000's would of thrown more, but I tuned the heads by the adjustable pressure regulator that I installed. I can see how far I can get them to throw and what pressure tomorrow if you need. I have to find my pressure gauge though. I made a port for it, and have it capped off now. I should of just left I there.

    ah. Ill take a picture or a video. I will turn 2 of my zones in the main area of my yard on. The kids in the neighborhood come play in my sprinklers.

    If I could invent a mp style head. I would some how figure out, HOW to install a LED or light in the head/riser of the sprinkler so when the heads spin, the light would be carried out through the water stream. It would look crazy at night time.

    Disclaimer: If anyone copies my Idea, it is documented here first. So pay me monthly installments for my idea.
     
  7. The RB rotators in your pic are fishtailing some. they definitely benefit from pressure regulation. I found them to be less wind sensitive and mist less than MPs. I'd like to see a du test between the two using the manufacturer's recommended spacing.

    The RB pic was taken on a system with 42psi static.

    Which brings up a good point, when the pressure is a tad to high the RB heads spin 1000 mph.

    I would be interested to see the toro heads in action bc they claim to spin at the same rate at any pressure.
