How to set up an automatic irrigation system for watering?

[KSB]

Hi I’m an absolute Newbie at this and keen to do a DIY set up of an automatic irrigation system for watering grass,gardenBeds & Pots some on the deck. Will appreciate help from the community starting from absolute basics. This is for a new Build where the wooden deck goes in Next week and grab the following week. 

cheers

Hi @JacobZ just returning to this project. Can you please explain in more detail how I can make room to run the line under the footpath please? It sure sounds doable! 
I’m planning to have a 2 or 3 line distribution on the tap is there any recommendations on how the initial setup next to the tap can be made neat maybe attached to the wall so all the pipes/distributor aren’t just hanging in the air? Else Boss may just scrape the project 😁. Photo attached along. I’m thinking maybe get the pipe coming down from the tap attached to the wall (What could be used to cover the gap from the tap tip to the wall if attaching pipe to the wall to run down), then where it touches the concrete thinking of putting a L there to run towards the grass then another L on the side of the concrete ( about a 2” drop on the side of the concrete) with a splitter one towards the grass for lawn and the other running from the concrete point towards the bins for drip sprayer line. Thinking of running each zone at different times? What do you think?

 

 

which will run all along the wooden fence.

Hi @R4addZ how deep do you think the trench will need to be? I’m assuming the height of the sprinkler + the connector +pipe below it! Seems pretty deep maybe about 6-8” it seems? Would I be on the right lines?

Hi @KSB 

It depends on the type of tubing you are using, if rigid, yes but if you opt for black polypipe, you can simply go that low at the sprinklers (or a bit wider) and do a slight s bend down to the level at each sprinkler (don't kink the pipe). Just make sure it is low enough not to be at risk of damage inadvertantly.

Hi @KSB 

I agree with @R4addZ in regards to the pipe work, I propose doing a dry assembly of the parts, you'll have a much better idea of how tall your assembly is once they are put together.

If you need further assistance, please let us know.

Hi @JacobZ  most of my grass isn’t a very wide area there’s about 1m or less at most places while the widest is maybe 1.5-2 m width as the deck is built all along (refer the image). You’ve suggested the metal sprinklers and heads but those I’m assuming will cover a big area if the area to be covered was wide but in my case most of it is pretty narrow. Can you suggest what sprinklers can I use to cover about a 1m or less throw in some areas while 2.5-3 in others preferable not pop up ones but installing on the side. The length of the section is about 30 odd meters but not that wide. The widest point will be around 2.5-3m. 

Cheers,

Hi @KSB,

Assuming you have the pressure required, then these K-Rain 180° Vari Flow Micro Sprayers seem like a good option. With a flow rate of 98 litres per hour, they can cover the wider parts with a 3m radius and in narrower areas can be turned down to reduce wastage.

Have you conducted a flow rate test? If not, use the calculator here - Flow Rate Test DIY with Bucket 

If you have the flow rate required, then these seem like a great option.

Let me know what you think.
