Project: Irrigating Courtyard Pots
Updated Tuesday 7 November 2023 – Steps 6 & 7
Micro Irrigation systems are ideal for minimising water wastage and ensuring your plants are getting the exact amount of water they need.
Drip irrigation is simple and cost effective to install and guaranteed to save you plenty of time and energy hand watering your plants!
We set up our own automated drip irrigation system in no time by following the steps below. You can turn water on manually, or set it up with a WX1 Wi-Fi Tap Timer to create a self-watering system for your potted plants. We used the Holman WX1 Tap Timer which allowed us to pre-program our ideal watering schedule using a smartphone. Please note the WX1 Tap Timer requires a Wi-Fi Hub to operate, available packaged as the WX1 Tap Timer and Wi-Fi Hub. However a single Wi-Fi Hub can connect up to 4 x WX1 Tap Timers.
Please note this video includes the discontinued BTX1 Smart Valve. We recommend using the WXT1 Wi-Fi Tap Timer in it’s place.
Count out the number of pots you’re needing to irrigate, noting how far apart they are. This will determine the number of drippers needed and the length 13mm Black Poly Irrigation Tube required for the project.
Measure the length of 13mm Black Poly Irrigation Tube needed from your tap to the last pot. Be sure to include enough pipe to clear corners or steps in the area you’re irrigating. To get around any corners, simply cut the poly, and connect each side to a 13mm Barbed Elbow. To prevent future leaks or drips, connect 13mm Ratchet Clamps on either side of the elbow. These are used to attach micro fittings to the mainline poly pipe to prevent leakage.
Tip: Roll your 13mm Black Poly Irrigation Tube out in the sun and leave it to soften for 20-30 minutes. This makes it much easier to work with. If your poly runs through any garden beds, you can use Universal Hold Down Stakes to hold everything in place.
Neatly line the pipe behind the pots. Once hidden, measure the length of 4mm Irrigation Flex Tube required to take water from your mainline poly to each plant. To connect the drip lines, punch a hole in the mainline 13mm Black Poly Irrigation Tube (using the 5mm Poly Universal Hose Punch) where you want to add each dripper. Using 4mm Barb Joiners, attach the flex tube to the main line poly and your preferred dripper head.
Tip: Measure out some extra 4mm Irrigation Flex Tube so you’ve got enough to move around or change the pots in future.
Connect your choice of K-Rain® Adjustable Trickler or PC Barbed Emitter. We used a combination of tricklers on spikes and dripping emitters. Centre the micro heads in each of your pots to one side of the plant or the base. Be careful not to damage any roots or seedlings when your pushing the irrigation spikes into the soil.
Connect an Automatic Tap Timer to your garden tap. We used a WX1 Wi-Fi Tap Timer so we could pre-schedule everything from a smartphone. For more information about setting up your Wi-Fi Tap Timer click here.
Tip: Use a 2‑Way Brass Manifold to convert your garden tap into two independently operated outlets. This gives you a spare tap to use for manual hand watering or to hook up a separate irrigation system down the track.
Alternately you could use a WX2 Wi-Fi Dual Outlet Tap Timer to set up two separate automated zones. This will allow you to water different types of plants without over or under watering. Please note that this Dual Outlet Tap Timer is only available with the Wi-Fi hub included.
Tip: We recommend attaching a 13mm Pressure Reducer to increase the efficiency of your drip system. As the name suggests, pressure reducers are designed to minimise water pressure before filtering it through the system.
