I think I'm good with one row. I may indeed need one or two large rotors for the widest parts.

Thanks again for pointing me to the proper parts. I'm all set for the Spring and it should install with not much difficulty.

If you are on a slope, you would generally water from the top. Your dimensions might allow for a single row with overthrow, or maybe you need a row at the bottom. Also, you would switch from the small size to the medium size of Rotator, as the width of the strip increased. They have a radius adjustment, for fine tuning.

Ok I'll get flow control valves.

Seems I can install 8 maybe 9 rotors with 16' radius @ my 37 psi and install down the the middle of the rectangle. I'll tighten up the spacing so I have definite head to head coverage.

Only need three zones, but I'll add an extra valve in my manifold.

Thanks for the suggestions.

Always get flow-control valves - pros know when and where they can do without flow-control zone valves, but the general public does not.

MP Rotators want more pressure than you would give spray nozzles, but their sizes and adjustability should make them a good fit.

Ok if I understrand it right these MP type rotors have a much lower flow rate. Good for me since I have low GPM. Less heads less valves. I'll go with these. Thanks. I should still get flow control valves right?

Ok I'll check into them thanks.

On a clay-soil slope, water from sprays will be rolling away before it penetrates to the desired depth. You might do better with MP Rotators, and a lower application rate.

Significant slopes in a design

Hi everyone. I'm planning a new front yard system for the Spring. Last year I put a small system in the back successfully thanks to everyone here who helped out.

Hardest part is the design. New area in rectangular about 130 feet long. Ranges from 12 feet wide to 22 feet wide. Entire length slopes downward from the house. Clay soil. 5.5 gpm, 37 psi. I plan on all spray heads.

Question is about the slope. Should I calculate that spray heads will cover more area due to the clay soil and slope?
