Is minimal installation of Hunter possible?

Eimertest showed 15 seconds, so 2400 liters/hour.

At what pressure? Or did you let it flow in without pressure?

I am also currently dealing quite intensively with the topic. Please keep in mind that the sprinklers need to overlap. So you will need quite a few. It will probably result in several zones that you will have to water one after the other. can tell you quite a lot about that.

Eimertest does not bring much because there is no back pressure. You will need several circles. Sprinklers must be planned head to head. A sketch will make it easier. You will need a sprinkler every 10 meters at the latest (in all directions). Such a sprinkler already requires 650 l/h at 180°. A well with a strong pump would therefore be an advantage. At your faucet, you can probably only operate 2-3 such sprinklers. what else do you want to know?

thanks, everything is fine with me. I may have expressed myself unclearly. I just wanted to express that you know the topic very well and can tell the OP a lot about it. As for me, I am currently getting familiar with it. It's almost a science in itself. But like with many things, when you engage with it, interest arises naturally.

I already understand. It was more a question of where you currently stand with your planning and if I could possibly help you.

Bucket test doesn't help much since there is no back pressure.

That's why I explicitly asked about the pressure. You must not make the mistake of letting the water flow into a bucket without back pressure. I also get excellent values there. With a pressure gauge and a shut-off valve set to ~3.5 bar — if something still comes out, you can measure it and define the number of sprinklers (or l/h) per zone.
