For me, that is just cutting it too close since we design to use 85% max of what the water supply is putting out.
It is possible if you go by the numbers, I just hate worry about whether it is going work until we turn the water on
I am really interested to hear the outcome and you will really like the 5500 when you get a chance to use it. RB's new price on it makes it even better, plus the 3/4 swing joints save a little coin too.
If I was to space these heads at 42' I would at least use the #5 nozzle and only put 2 heads per zone. Not sure if I would use the 5500 on this job. It probably would work but may just go with shorter spacing in the name of efficiency.
