Spacing residential rotors more than 40' feet

[ArTurf]

Do any of you space rotors more than 40' in ar residential situation. If so what size nozzle do you typically use? I generally use Rainbird 5000s so I would have to at least use #5 nozzle which is listed at 45'. The spacing I would need to use would be 42'. Do you think the #5 would reach sufficiently for head-to-head coverage?

It doesn't make sense in a head-to-head residential system, even if you got pressure to burn. Long-distance rotors use too much water.

Mind you, that applies to systems with basement water meters, and less than 15 gpm in a zone.

Not everyone has basements and less than 15 gpm in a zone.

Everything depends on having enough pressure & flow.

I have approx 14gpm @ 50psi. The area watered is 42 x 82. I was thinking of 3 stations each with 2 heads with a 5 or 6 gpm nozzle. But was worried that trying to throw long distances might not give good coverage. The other choice would be MP's spaced 21'.

You can't do it with 14 gpm without adding more or about the same amount of valves using 30-35' spacing. The 5004 is not meant for your application and large gpm rotors eat up water drastically once you get to that range.

Anything above 40' we use the RB 5505 and would only implement this head on a design that has 50 plus gpm.

just set the WABAC machine to 1978 and use popup brass impact heads with 3/16-inch nozzles

Been kind of thinking about using the 5500 on some high end jobs. How do you like them?

Did you get your WABAC machine at harbor freight or on Ebay? Forget it, found it between the pigtails and the rebar benders.

I'd do mp's before 5500's at that pressure if the water quality is clean enough.
