Hello Birgit,
I have put it together for you. It will be even simpler and cheaper
You get:
5 x Hunter PRS40 housings (these have a pressure reducer)
3 x Hunter Rotator MP2000 heads 90° to 210° (flow rate each 0.18 m3/h)
1 x Hunter Rotator MP right strip nozzle head (flow rate 0.05 m3/h)
1 x Hunter Rotator MP right strip nozzle head (flow rate 0.05 m3/h)
Total flow rate 0.64 m3/h. You can easily manage that through your water pipe or a reasonably good cistern pump. So one circuit is enough for you
1 x Rotator adjustment key
50 meters PE pipe DN25 (depending on installation)
X fittings for branches and sprinkler connections
2 x water boxes
1 x switch or irrigation computer with two outputs
1 x compressed air connection (coupling to e.g. Gardena)
At the end of the line, you can connect a coupling to e.g. Gardena and attach a piece of hose. That way, as desired, simple switching between the water tap and the cistern.
Now you can either start the irrigation via the water tap (or turn on the cistern pump) or get an irrigation computer with water connection (two outputs) such as from Gardena. That way, you don’t need a box with valves, control lines, a “real” computer, etc.
Overall, a pragmatic, robust, and cost-effective solution. Since the flow is so low and pressure-reducing housings are used, the piping can be done accordingly. The sprinklers can be adjusted for throw distance and width.
yellow dots are the water boxes (you can position them anywhere, just pull the line there)
yellow line is the supply line for the water boxes
black dots are the PRS40 housings (and the corresponding heads)
black line is the supply line for sprinklers
pink semicircle are the MP2000 90-210° heads
blue rectangle on the right is the MP right strip nozzle head
blue rectangle on the left is the MP left strip nozzle head
I was not sure where your water connection is. I simply routed it towards the technical room.
