I have a 37'x60' area with less than ideal layout of spray heads. The heads are spaced 10' down each line of pipes that span the 60' length. But the widths are horrible: +----edge of sidewalk--------------------- 7' of turf with sloping elevation down 1 foot +----irrigation line 1----------------------- 13' of turf with sloping elevation down 1 foot +----irrigation line 2----------------------- 17' of turf +----irrigation line 3 and edge of turf---- landscape plants +----edge of house My gpm/psi only permits me to use 12' nozzles and so I end up wasting a lot of water and still have troubled areas. Through calculation (pressure loss) and by experimentation I have determined that if I eliminate every other head, I have enough capacity to use rotary heads or rotator heads at 45 psi. Using 7' of swing pipe, I can relocate the heads on line 1 so that they are adjacent to the sidewalk. Also using swing pipe, line 2 heads can be moved 1.5' toward the side walk. This would result in a near square layout (20'x18.5') which would greatly improve to the existing layout (a mix of 10x17, 10x13, 10x7). Does this look like a good strategy or should I just relocate line 1? I tried several of Hunter's MP rotators and Hunter's PG Juniors side by side as part of my experiments. It happened to be a windy day and the Junior was much more effected by the wind. I noticed that the PG Junior has less nozzle selections as compared to PG Senior. That makes getting the precipitation rates harder to match the corners to the sides and to the fulls. I am curious which would be better for this application or perhaps some other strategy would be better.
