Added three heads, learned something

Noone in my family cares about my sprinkler system, but I can talk about it here.

First I combined three sprinklers from two zones to one. Now an extra valve. I have low pressure. I used a 90 degree elbow leading to two heads. Sure enough they had poorer performance than the one head that had a straight line from valve to head. Learned something.

New zone is three Hunter MP rotators. About 80 feet of 3/4 PE. I cut the sod put it aside. Used a pickax for the trenches. Rock, rocks rock rocks. Took about 10 hours for the job. Needed 6 bags of topsoil to replace void caused by the rocks. Replaced sod. Flushed, adjusted then put in MP rotators. And........they work great. And I can probably add one one MP rotator if needed.

Phase 4 in maybe 6 years when the kids give me back their play area.

"Noone in my family cares about my sprinkler system,..."
Man, I understand that one.
I use my wife's flower garden to test different nozzles that I haven't used before so I have some clue as to what they do.
Her only comment: "replace what you kill." Which I have done. A lot.
And, of course, I always find something in the 20 year old system that needs fixing.
They quit asking what I'm doing and I quit trying to explain.

I understand, Backflow is great too.

Almost no body knows what it is.

What do you do?

I could tell you, but you would not understand.

I currently have a zone at the back of the property used as a "test facility". 8 rotor zone that consists of Hunter, Toro, and Rainbird rotors. I'm testing real life nozzle performance/turf quality. I've already begun to notice differences in the appearance of the grass.

Initial indications?
Which is better?

So far, I am leaning towards the Rainbird 5004 with a 2 gpm nozzle. The precip. rate is lower than the others, but it appears to be doing well. It seems to yield a finer blade of grass, but more dense. The I-20 and Toro T-5 come in second, but the durability of the I-20 seals the deal. Both seem to yield a thicker blade but not as dense. My main reason for the experiment is to determine the visible difference between higher precip rates (3gpm nozzle) and lower precip rates (2 gpm nozzle) as they pertain to a clay soil. I'll get more technical with my numbers at the end of the season, when there is time to do so!
