RASEN BEWÄSSERN - der RASENFREAK zeigt seine Bewässerungsanlage

Hello dear lawn freaks, welcome to a new video from Lawnfreak Andreas Krauss. Today is about my irrigation system. You asked so many times: What kind of irrigation system do I have? How did I do it here in our house and in the garden? And that is why we are now filming directly from our storage room. Please don’t look closely! And I tell you how we built this up. So here is our main connection, our pipe from the waterworks, from the street. Here is our main water meter. Here the two shut-off valves and directly from the main line there is an outlet here, directly outside, via the outside water meter.

00:50 - I hope you see that, over the outside water meter, directly to the outside tap. Where my irrigation system is connected. Why are we doing this? First of all, unfortunately, we have to water the lawn with our fresh water. We cannot drill a well here because the groundwater is too deep here. And that it would have cost an incredible amount of money. And luckily we have relative cheap fresh water. You pay for fresh water and you pay for service water, i.e. for wastewater. And the wastewater prices are usually significantly higher than the fresh water prices. I have about 400 € water costs for my garden irrigation per year. And that’s why an outside water meter, then you know exactly how much service water you don’t have to pay And yes, now we go outside and look at the tap outside. So freaks, this is the fat outside tap here.

02:00 - There is the connection box from Gardena for the irrigation system. And that’s where the hose comes in, directly. Now we’re going to close because we want to turn the water on too. Then we have the main valve here. That’s where the main valve comes in. Here the six valves come in for distribution. Here we have „Brehms animal life“, worms, all sorts of crawls and curses around, and is now fleeing. There you see… this is my wife by the way.

02:50 - Now you can see the main tap that goes directly into the irrigation distribution here. We solved this with a main valve and with two valve boxes for the individual irrigation lines. I had to install six irrigation lines, to have enough pressure on every water sprinkler, every lawn sprinkler. That can be calculated. Gardena has a nice tool where you can calculate exactly, depending on the water pressure, how many sprinklers you can connect a line of water, a pipe. Then there is the distance to the last valve.

03:33 - So we’re here, here we are, and our last outlet, I’m running there very quickly, our last valve is at the very end of the property. On the far corner, where my tee is. Here there, and these are easy, I mean, my property is 50 m long, plus around the house, that’s 70-80 m. Here, there, there is the last valve, there, and there must still be enough water pressure, to operate this sprinkler sensibly. So freaks, well we built 25 years ago and I haven’t even thought about an irrigation system at all. That came much later when the lawn became more and more important.

04:33 - And then we started to move the whole irrigation system on our property afterwards. It was horror. We have laid the pipe in the far corners. You always have to dig so deep, so wide, so deep, dig such a shaft, in order to lay several pipes even then. The whole single sprinkler points are controlled. It was amazing. So if you’re somehow buying a new piece of land right now, make new last, at least put the pipes in the ground. This is a pig work to do afterwards, and you can see it for a very long time where the lawn was pricked.

05:19 - So now we’re going to install the valves here. They have to go out in winter because they are not frost-proof. Now it should be warm the next few days, it should be nice. And it rained too little again, even though it rained so much in January / February. It has hardly rained the last few weeks. We had rain once, that was only 3 l / m². I need 9 l / m² twice a week so that the lawn is adequately supplied with water. I also fertilized, and the fertilizer is now urgently in the soil. So that the grass finally starts to grow properly in warm days. Let’s vacuuming out first! I always do it nicely, because of course the seals should not get sandy or dirty. Therefore, at the beginning of the year, vacuuming out, then you can install the valves sensibly here Yes freaks, this is my box. This is what a valve looks like. They have been around… well how long?… 25 years, so for more than 25 years, there are these valves from Gardena.

06:50 - And that hasn’t changed, it still exists today. They are a bit sharp, so you have to be careful with the assembly. It’s pretty easy to hurt yourself there. So then you take, where do you see that best now, then you first take these connectors out of here. To do this, pull these clips out, pull them out of here, and you can see there is still dirt underneath. There is still a lid. So now there is a flow direction, there is an arrow on it.

07:31 - The water comes from there, so the valve has to be installed around it. I do, it took me a long time to get it right, I always put the long one on first. Put in, push all the way through, and now you can fumble the short nozzle in between relatively easily. So now it’s in there. And now you can screw the short connector into the valve relatively easily. Zack, zack, zack, zack, that works just fine. Screw tight until it stops. And then you pull the valve back. Locks the valve with these two clips. And a valve is installed. Okay, three valves. Then there are these control units. It is a control unit. Then a 9 volt battery comes in. I hope they’re still good.

08:46 - Round is plus, zack, and also with a blue sticker on it, done. Red, now we don’t have red, we now have white, dirty everything dirty. And these control units, which are programmed afterwards, with such a programming unit. And it has no color, this is my new strand, that is the irrigation for the south edge. I installed this valve when I installed the south edge with the fan sprinkler. Arrived later, I still had one strand free. It’s still good to leave a pipe strand free, to maybe do something again correct or improve. It was great that there was still one strand left, so I was able to water the south edge with an additional sprinkler. You can see that in this video what I did back then. I don’t really know when I installed it, after 3/4/5 years? 20 years ago, I bet. I’ve had it for 20 years.

09:58 - „2004, 16 years ago!“ The problem with my old system is the pipe that I installed in the lawn, these were still special Gardena pipes. They weren’t standard, not inch, as used in industry by default. Gardena thought they were making their own pipe diameters, to keep the gardena system incompatible with other irrigation systems. Gardena gave up on that at some point, just good! And now Gardena also offers inch tube systems, this means that the Gardena system is also compatible with other systems, such as Rain Bird or Hunter. That’s really great. Sure, there is more competition. For example, you can now mount Hunter sprinklers on the Gardena system.

10:52 - It’s a cool thing, of course, and I’ve already done it. Because the Hunter sprinklers are also very, very, very high quality. But Gardena has also improved there, so I think… zack… that has also evolved. Gardena is the undisputed leader, but Hunter and Rain Bird are really interesting alternatives. Then let’s put the main valve in here. Are you filming? Yes! The huge advantage of using a main valve here is: I can control the entire system centrally via this valve, or switch it on and off.

11:45 - I installed a rain sensor up there, and it hangs on this cable, and this rain sensor switches off the system when it rains. And of course this works best if you have a central valve. That’s the big trick, you can have a rain sensor and you can install a moisture sensor. At least that was the case earlier. And of course a central valve is required for this, which can be switched on and off centrally. So you don’t have to control every single valve here. And for this reason alone, a central valve is also totally sensible and smart. Exactly, that’s the last control unit. The cable is now plugged into this control unit, to integrate the rain sensor with it So, cool, done! So freaks… yes tight… tight Cool, now we open the main valve Zack, on, now there is pressure on it. You see a little water is coming. You don’t see! There’s some water down there, so it’s a little leaky. So now we turn on the yellow. pop And we have irrigation again. Ohhh… no…

you see, it’s not okay, quickly out again! 13:49 - Quickly out again… main tap… that was close! That was close, it’s broken! Yes, one is broken, I have to replace it right away. So we open again… Ey… go out! And soaking wet. Yes… crap… that’s what happens If the valves are still OK, you can press the button up here, Push a button… push a button… can’t you? Come on! Also no longer works. Hah, what did the Lawnfreak forget, what did the Lawnfreak forget here? Then he forgot the battery! Because if you press the button up here, then the valve also turns on for half an hour.

15:00 - So here pressed, exactly half an hour running time. Without programming the valve, but you should insert a battery. So that’s better now. So if you press here now, press there, Ahhh… now he has switched on for half an hour. And now my south edge runs there! The sprinkler is running, yeah. So that’s it for today. Thank you for watching. Now we have irrigation again. It is a little windy, of course you should water if it is as calm as possible. It’s great to water at night.

15:50 - I actually always do it at night, at night at twelve to four in the morning. The best way to water it. But first I let it go anyway. Maybe one thing at the end. How do I actually know how much water I sprinkle on my lawn? And a really simple rain gauge has proven itself really well. For a very slim euro. With such a simple rain gauge, I know exactly how much water I sprinkled with the sprinkler in half an hour. Watch out a little. Top So dear lawn freaks, but that’s it with the topic of irrigation. The last thing I will show briefly is: Half an hour watered here with the fan sprinkler, and we have a lot of after all, we water after all, 7 l / m². Cool! Thank you for watching. Until next time. Your Lawnfreak bye .
