Cistern for garden irrigation - Which pump?

thank you for your answer. Originally, I wanted to implement it like my 1st plan (see attachment). But here, I have to climb down with a ladder every time (for maintenance, repair). I would rather not do that. Thanks to your suggestion, I believe it is better like my 2nd plan. However, here I need 3 fittings (instead of 2 as in your text). With this solution, I will probably lose a lot of pressure. Have I made any mistakes here? Maybe you have better ideas?

How did you finally do it in the cistern? And what are the experiences? Thanks

I bent both pipes "with force" and then used a 90° connector. It was cold and the pipes were hard to bend. But I managed it.

Which of the sketches did you then implement?

None of them but Plan 3 (see attachment)

Hello everyone,

I am bringing up this topic again because our outdoor facilities will be partially worked on soon, and I want to start planning. I have inserted a picture showing what it looks like at our place.
- Purple the house
- Gray the paved areas
- Green is to be planted. However it should look later on.....
- The blue circle on the right at the corner of the house is the cistern (~ 7.5m³)
- The black line is the power supply which is switchable inside the house
- The narrow blue lines with the Xen at the end are meant to indicate the points where I would like to have tapping options or could imagine having them.
- This should all happen normally with a hose. We basically want to do it ourselves, and nothing should be watered automatically, etc. It is kind of a lifestyle feeling, manually watering the garden.

Based on these ideas, I have the following questions:

- There have already been some tips about pumps here. If I use the Gardena comfort 6000 for my application, I am probably not making a mistake, right?
- How do I best lay power cables? I now come out of the wall with a cable about 20m long. Should I lead the cable into the cistern, put a Schuko connector on it, and then just plug in the pump? Or how does one proceed here? Cable of the pump out of the cistern and then connect outside?
- How must the cable be routed underground?

- How is the pump fixed in the cistern?

- I would now plan a normal tap column at the 3 planned tapping points. How is the pump’s water hose routed to the different points here? Can you just install a normal distributor and then use a normal hose, or are there special hoses?

That is enough for the beginning. More questions will certainly come up during the further discussion.
I hope you understand what I mean.
Thanks and regards

You can take the Tipp pump or another manufacturer if desired. From the pump, use PE-HD pipe/hose. DN32 is best. Consider whether you want columns. Floor boxes would be simpler and cheaper. I would rather recommend Rainbird or Hunter. Gardena is not so robust and you only pay for the name. The power cable belongs in a protective tube. The connection can be made in the cistern (above the overflow). Whether by plug or fixed wiring, I would connect it in a weatherproof housing. The switch is practical for winter. In summer, the (empfolene Tipp) pump always has power. As soon as the pressure is reached, it switches off. If you connect a hose and open the sprinkler, the pressure drops and the pump starts...
