Water extraction points / water pipes / irrigation in the garden - ideas

Should the sprinklers actually be placed all the way at the edge or slightly inset? Or do they also spray slightly backwards?

All the way to the edge. Since you irrigate head to head, the sprinklers are set slightly "wider." This way, the edge and the adjacent sprinkler are overwatered.

Unfortunately, I am being a bother again. You once wrote that for drip tubing, one should use the XFS from Rechtsanwältin Bird.

[*]So, do you have some components from Hunter and others from Rechtsanwältin Bird? Or would a drip tubing from Hunter not be so good?
[*]Does the XFS still require additional accessories to connect it with the DN32 pipe? Pressure regulation and filtration?
[*]The XFS can be laid both under the soil and on the soil? Does that make a big difference or what are the advantages and disadvantages?

Thank you very much

I always try out the plan that was drawn on paper above ground first and only then bury the sprinklers. This way you can immediately see where there are problems and fix them right away.

Mixing sprinklers and nozzles from different manufacturers is largely unproblematic. For example, I have Hunter housings (PROS-S and PRS30) and Rainbird R-VAN nozzles. Of course, I wouldn't mix PGPs and PRO-S on the same line.

But I am only an interested amateur when it comes to irrigation systems.

You can mix the manufacturers. You need a reducer for the drip hose because it only has a 17mm diameter. The XFS withstands pressure well. Therefore, a pressure reducer can be omitted if your pump does not provide significantly more than 6 bar. At the extraction point, the pressure is usually below 4 bar. We only use the XFS now. I have not tested Hunter for drip hose. Pressure resistance is certainly an issue. Many only withstand 2.5 bar…

Whether the installation is above ground or not depends on several factors. For ground cover plants or hedges, I would install above ground. It grows on, but you can easily check the function and also more easily change or replace something. In public areas (which is not relevant here) it is rather buried because of vandalism…

I have now also made a calculation for a 6-way distribution box. This costs just under €600 at DVS. With self-construction, you come to €250-300:

Hunter solenoid valves PGV-101G	6 pieces	€17.00	€102.00
Rectangular valve pit	1 piece	€60.00	€60.00
Dura cross piece 1" 3x internal thread 1x external thread	3 pieces	€9.00	€27.00
Dura connector 1" external thread x internal thread	7 pieces	€4.50	€31.50
Dura T-piece 1"	1 piece	€6.60	€6.60
Dura elbow 1"	1 piece	€6.00	€6.00
Unidelta connecting sleeve DN32 x internal thread 1"	7 pieces	€1.80	€12.60
Ball valve	1 piece	€10.00	€10.00
Total			€255.70

Should one actually put a filter in between? For example, Rechtsanwältin Bird Filter?
