Irrigation system for a large (still) empty plot

I would now have taken the normal PE HD pipe (suitable for drinking water). It is pressure-resistant up to 12.5 bar. Now there are also more expensive LDPE pipes, which are suitable up to 6 bar. These are more flexible. How is this handled in practice? The main lines, that is from the pump to the individual valve boxes in normal PE pipe with 12.5 bar pressure resistance, and from the valve boxes to the regenerators then with the more flexible LDPE pipe with 6 bar pressure resistance, or simply everything with the PE HD pipe? Regards

All PE HD 16 bar. The soft one kinks too easily and also tends to be pinched. This extra cost is really worth it. Best to open the coil and leave it in the sun, then unroll it with two people and install it.

Ok. I have come across the next "problem" - topic sprinkler connection:

There is the HSJ Swing Joint from Hunter. The problem I see here is that I might not be able to position the sprinkler as easily where I need it.
I am more flexible with the Blu Lock system. There I can cut the hose length as needed and position the sprinkler more flexibly.
Now I have seen that Hunter also offers a similar connection. Just with slightly different connection technique from fitting to flexible hose.

Do you know all 3 variants? Or has someone else maybe already tested the 3 variants? Which one is the most practical? (for a one-time installation of ~40 sprinklers)

Yes, I know all three. Blu lock with the expensive fittings are the best and most flexible. Still, put some PTFE tape on the thread during installation. I don't use anything else anymore.

PTFE tape is the normal Teflon tape, right?

For irrigation through wells, I should probably install a filter at the front of the main line, right?

Do you have a tip for water outlets? I think the best thing is simply a housing where the PE HD pipe ends with a 1/2" coupling and then a 2m hose plus a nozzle, so that at least a watering can can be filled. If you need to go further away, you can get another hose for extension. I wouldn't switch the water outlets on and off separately with a solenoid valve. That is probably inconvenient in practice. Regarding pressure loss, of course no circuit should be open during the day. But they are supposed to irrigate rather early in the morning anyway.
