Optimal pipe diameter irrigation system

L-shape is easy to plan
With the area, you can also work with larger sprinklers.
More than 2-3 sprinklers per zone simply won't work due to the flow rate.

Electricity, network, and KNX I have in the garage; from there I can distribute everything or locate the control there. Only water is not available there. Otherwise, I try to avoid more drillings through my WU basement, besides the annoying discussions with the general contractor, drilling, sealing, etc. is not exactly cheap.

The only hurdle: water is on the left side of the house, electricity and the rest on the right side of the house.

What do you think about drip hoses, for example for hedges or even vegetable beds?

Is not a hurdle. It doesn't matter from which side the water or control line comes to the valve box.

Drip irrigation is great for hedges and beds. Can also run in strong sunlight. Recommend XFS Dripline.

Sorry but absolute nonsense calculation.

I then ask for a correct calculation instead of meaningless comments.
