Empty conduits on the property - ideas? - It's not too late yet :)

So I'm at home at the computer.
Green: don't you irrigate the top right corner? I don't see any sprinklers here

Yes, you hit the nail on the head right away there will probably be a raised bed or something like that, since the garage is a bit lower > so it won't be completely lawn. That's why I put an MP3000 on the right instead of 2000 as you suggested and would set it higher so that it covers the corner as well or at least waters the lawn a bit.

You could put watering sockets on one line. Saves a valve or one as a reserve

Yes, you're right, but if I see it correctly, I would have to dig a channel from south to north on the left for that, which I want to avoid because everything is compacted on the left side of the house. Maybe connect it directly at the distributor? And actually, a valve control here doesn’t make much sense, does it? So an on/off valve would actually be sufficient here, otherwise you'd always have to open the valves first before you can use the water socket.

Pink: please make a separate circuit for the tree. It has a very different water requirement than the beds.

Actually, no tree is planned there, we would only plant a tree in zone 3 on the left, but do you really have to irrigate it? Maybe the MP rotators that water the lawn are sufficient? And the tree can be watered manually with rainwater on hot days (rainwater from the rain barrel has to be used anyway).

Blue: with that length I would rather divide it into two times 25 meters. Supply it once from the left and once from the right. Keep it in one circle or better make each an extra circle. I also suspect different water needs here.

Okay, I feared that, then I will split a channel directly into 2 lines at the distributor.

Since you lay almost everything in one main trench, you will need a mini excavator anyway. With 4 lines and fittings, the trenches for a normal trenching machine are too narrow and/or not deep enough.

Yes, I'm afraid of hitting a line later when a swing/play tower is concreted in or something like that, so better not so many distributed lines - that was at least my thought.

No irrigation on the left side of the house after all? If you’re still undecided, I would lay a line and put a plug on it. In case you ever need it, you don’t have to dig up your garden.

There is mainly a terrace and paved path and a small side roof. Only the green strips/flower beds in the "pink zone". How is it actually with the PN16 PE pipe and compacted mineral mixture or vibrating plate and paving on top, can I damage the pipe with that or should I put sand on it first and then the coarse mineral mixture and then compact it with a vibrating plate?

Different water requirements can also be compensated to some extent with different drippers (different dripper rates).
I decided not to control the watering sockets with valves at all but always have water on. I think that is more practical.

Just a stupid question. Do you really want to run the line up left in zone 3 all the way to the middle and then back to the right? You could take the sprinkler down right along with it. You did plan pressure-regulated risers, didn't you?

Yes, you’re right, water sockets should actually always be ready for use, I see it that way too. I would now put them on one line.
Yes, I thought you should always approach in the middle to ideally distribute the pressure, but yes, you’re right, I can save myself the trench to the middle.

The pipes (especially at the stressed points) were sanded. In principle, you are right about starting in the middle. However, since you will be using pressure-regulating housings, it does not matter much. One of the big advantages of these housings. You just need to have enough pressure in the line...

Hi everyone,
How do I best connect these four rotators to the supply line? Three T-pieces in a row?
I have laid a second supply line to the right rotator (for the socket next to the rotator), which I could use for the fourth rotator in case the water pressure is too low for the four rotators.

Fittings do not fit directly one after the other (unless they have threads). Therefore, there must always be a piece of pipe in between. How do you connect the sprinkler housings? Do you have the complete connection sets? There are several options. If you have the sets with T-pieces, do it as planned. At the end, a plug.

There are these multi-way distributors that are also used in the valve boxes (e.g. IG43660D0N320 at DVS). Wouldn't that be a variant with fewer parts?

they have more individual parts than three fittings with threads. I’m still not sure where that’s supposed to be. There are 4 sprinklers on a 2-meter diameter...
