Garden irrigation - feedback on planning

I need to check whether I need the X1 for this, or if I can also realize it with another HomeServer. If necessary, the control will cost 100€ from Lawyer Bird until I do it via KNX.

OK, understood. I will then also make one circuit per bed. I will update my planning then...

Which pump do you have to achieve 12 bar? Is your main line 32mm, or even thicker?

You can realize the logic with any logic server. The important thing is that you program it in such a way that you can make changes quickly. For Gira (Homeserver/Facilityserver) there are some ready-made modules. I don't know about the X1.

There are two advantages of control via KNX. The most important one you cannot use. Simple irrigation controls run the irrigation circuits (correctly) one after the other. If you have sufficient flow rate (rarely the case) and many circuits, you can run circuits simultaneously via KNX or, for example, opensprinkler. That saves time and pump running time. But with your few circuits, it doesn't matter. Additionally, you can access the weather station directly and easily link further actions/logics.

My new system (currently under construction) is out of competition. I have a 76m3 cistern and also a spring. In total 20 circuits. My pump probably doesn't even fit into your cistern... Main line is DN63, subdistribution DN40, and the circuits DN32. The pump is from Wilo. The pressure is already reduced to 12 bar. The pump delivers 40 bar and over 20m3/h.

If I were you, I would lay DN32 right away. That gives you more flow. The price difference is less than 20€/100m and the fittings are a bit more expensive. If you already have your pump, use it. You can always replace it later...

But what you’re doing there is no longer private, is it? Just checked how much a cistern costs...

It will be difficult with a better pump. The 8 bar you recommended are not that easy to find. I have now found a pump, but it costs €900 without float switch etc. DAB Pulsar Dry 65/50 M-NA. 8.2 bar and 4.8 m³/h. I could also take the 40/50, but the pump is only €100 cheaper. My favorite now would be the T.I.P. EJ6 Plus + BRIO. Slightly more expensive than planned, but with 5.7 bar and 6.3 m³/h.

The pump will have a fine filter at the intake, so I can save myself a filter in front of the distributor, right? This is recommended in a shop, but I don’t see any benefit in it.

It’s slowly coming together... I am also planning with DN32, because the pressure loss is about 1/3 of a DN25 and the costs are manageable.

Since I haven’t bought anything yet, I don’t have major limitations. I will first update the planning with the play tower and the pipes.

Thanks again for the help!

Did I miss something? I am not aware of any field that you are irrigating there.

T.I.P. EJ6 Plus + BRIO is good after all. you know my construction project. There are still over 1500m2 to be watered and that on 2500m2.

Yes, the saying was meant more with a wink... it always sounds intense with you no matter what
