What size pipe for irrigation system with 14 drippers?

Just Starting Out

What size pipe for irrigation system with 14 drippers?

I am growing 14 jasmine climbers around our small yard and sidepath up some screening that i built.

I want to install an automatic irrigation system but not sure on a couple of things.

The total length from the tap to the last plant is 37m with 3 x 90 degree turns around the yard.

Tap fill s a 10ltr bucket in around 26 seconds.

Not sure what size piping i need to run?

And figuring i only need 14 drippers at each plant but not sure which ones work best for this project?

Hi @Koops 


Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thanks for sharing your question about building an irrigation system.


There are a few things to take into consideration regarding your irrigation system. But before I make any recommendations, would it be possible for you to post a few photos of the location? This will give our members a better idea of the layout and how far apart the jasmine are.


Generally speaking, I try to future proof my installations as much as possible so between the 13mm and 19mm, I suggest going with the 19mm to allow more water to flow should you update or change your system. I'm very keen on adjustability and often suggest using the Pope Veri-Flow Threaded Trickler Dripper - 10 Pack.


I also recommend having a look at these guides - How to install a drip irrigation watering system and Understanding a drip irrigation watering system by @Adam_W 


Here are some excellent discussions regarding irrigation systems:
