Do you want to install a smart irrigation system so your garden gets water automatically? In this practical step-by-step guide, you will learn how to install a reliable irrigation system yourself, suitable for connection to a tap or (rainwater) pump. This ensures your plants always get exactly the right amount of water, without you having to fuss with a watering can or garden hose every day.
At Plukkers, we chose a solid, leak-free system that won't let you down. Water is a precious resource. If you connect everything correctly, you prevent waste and are guaranteed years of ease of use.
Step 1: Preparation: Map out your garden
A good irrigation system starts with a good plan. Sketch your garden and indicate where the plants, borders, paths, and lawn are located. This way, you know exactly where you want to:
- lay the main pipe
- place drippers, drip hoses, or a soaker hose
- install couplings or taps
By planning ahead, you can install it purposefully and ensure you have all the necessary parts on hand.
Step 2: Choose your water source and control
Our system connects to a standard ¾ inch tap or a pump. Is your connection different? Then use an adapter.
What is the capacity?
With normal water pressure (2.5 to 4 bar) you can:
- water 250 plants with drippers
- or use 250 meters of soaker hose or drip hose
Too much pressure? No problem: all our drippers and hoses have a flow regulator.
Too little pressure? Then divide your garden into multiple circuits. Use a water distributor to supply water to each circuit separately.
Manual or automatic?
Do you want to water more than 250 plants? Then divide your garden into different circuits. You connect these circuits to a water distributor, which you then connect to your tap.
Next, you choose whether to operate the system manually with a tap, or automatically with a water computer. You connect such a computer to the tap and simply set it via buttons. Working with multiple circuits? Then you need one water computer per circuit.
Think about this in advance:
- How many plants do you want to water?
- Is your water pressure or pump powerful enough?
- Do you want to switch manually or work automatically?
- Are you going to expand later?
What you need to get started:
Step 3: Place the main pipe
The 16 mm main hose forms the heart of your system. You connect this to the tap, water distributor, or water computer with a tap connector or nipple and a coupling set. Ensure everything is tight and leak-free.
The hose can be secured above ground with ground stakes, or be buried (at least 60 cm deep). Roll out the hose along all the zones you want to irrigate. At each point where you branch off to a zone, cut the hose and connect it with a 16 mm T-piece.
Provide each branch with a tap so that you can shut off zones individually. Ideal if you have nothing growing in one bed for a while. For connecting parts, use the coupling tool for 16 mm connections – it makes working a lot easier.
Do you want to expand in the future? No problem. You can expand the system at any time with extra couplings, drippers, or hoses.
What you need to get started:
Step 4: Choose your irrigation method: drippers, soaker hose, or drip hose
Drippers, a soaker hose, and a drip hose are the most ideal irrigation systems to water your garden efficiently and automatically, depending on the plants and how you want to distribute the water evenly. What exactly is the difference and how and when do you use them?
4.1: Drip irrigation
Drip irrigation works with drippers. These are small nozzles that release water drop by drop at each plant. They provide targeted water and ensure precise irrigation. You use drip irrigation for individual plants such as tomatoes, berries, courgettes, and cucumbers.
To work with drippers, you must first lay an additional 16 mm hose between your plants. You simply connect it to the valve of the main circuit, which you previously installed at the beginning of the bed.
Next, use the punch tool to insert the drippers directly into the 16 mm hose. There are 3 types of drippers, each with its own flow rate. You can choose between 2, 4, or 8 liters/hour. For a zucchini plant, it is best to use an 8-liter-per-hour dripper, while a head of lettuce only needs 2 liters per hour. You can combine different drippers on one circuit.
Finally, you need to get the drip to the desired location. You do this by attaching a 4 mm hose to the dripper. Cut it to the desired length yourself. Place the end of the small hose into the 4 mm hose stake. This way, the drop lands exactly where you want it, giving you a tidy and organized watering system in your garden.
What you need for your drip irrigation:
4.2: Soaker hose
A soaker hose is porous and lets water seep through its walls along its entire length ("sweating"). Ideal for wide beds or dense rows of crops such as carrots, beans, or lettuce. Lay the hose in a loop using a T-piece so that water flows in from both sides simultaneously. This distributes the pressure better.
You connect the soaker hose to the valve of the main circuit, which you already placed at the beginning of the bed. Then, lay it between the plants and, when finished, simply cut it to length with the cutting tool. Seal the end of the soaker hose with an end cap.
Our soaker hose provides 2 liters of water per hour per running meter.
What you need for soaker hoses:
4.3: Drip line
A drip line has an opening every 33 cm that releases water. Use it for straight plant beds with regular plant spacing. Each opening releases 2.2 liters per hour.
You simply connect the drip line to the valve of the main circuit, which you already placed at the beginning of the bed. Then, lay it between your plants. Seal the end of the hose with a 16 mm end cap.
What you need for drip lines:
Testing and commissioning the system
You have now successfully installed your smart irrigation system in your garden step by step. It's time to check if everything is working as it should.
Start with a thorough check: are all pipes, couplings, and drippers firmly attached? Check for visible leaks, especially at T-pieces, shut-off valves, and the connection to the tap or pump.
Next, open the main valve and close all smaller valves. This allows you to bring the system up to pressure gradually. After that, check if your water pump does not turn on or your water meter is not running. Note: only do this when no other water is being used in the house. If the pump is running or the meter is ticking, there is a leak or drip loss somewhere.
Then test each zone separately:
- Open the valve for the first zone.
-
Check if the drippers are dripping, the soaker hose is sweating, and the drip line is dripping as expected.
-
Pay attention to uniform water distribution and whether all components are functioning properly.
-
Repeat this for each zone.
Everything in order? Then you can let the system run automatically. Set your watering schedule via the irrigation controller. You choose how often and for how long you want to water, tailored to the season, soil, and plants.
Example schedule:
- Greenhouse: 15 minutes daily
- Outdoor beds: 15 minutes every 3 days
With a layer of mulch, that is often more than enough. And the great thing is: with a well-functioning irrigation system, you give your plants exactly enough water, save time, and keep your garden healthy — even during a heatwave or while on vacation.
Tips and benefits
Benefits
Time-saving: automatic watering saves a lot of work
Water-saving: targeted water use reduces waste
Better plant health: even watering prevents drought stress

General tips for installation
-
Map out your garden: draw zones and determine where watering is needed.
-
Check water pressure and connection: ensure sufficient capacity and reach.
-
Work with logical zones: group plants with similar water needs.
-
Test beforehand: check the coverage and adjust if necessary.
-
Prevent clogging: preferably filter water and clean the system regularly.
In conclusion
Drip irrigation is a smart and sustainable choice for any garden lover. It delivers water directly to the roots, prevents waste, and supports even growth of your plants. Thanks to the flexibility of the system – from manual to fully automatic – you can start small and expand whenever your garden requires it. It also works perfectly on the balcony, in a cold frame, or in a greenhouse. And the best part? Your garden is watered at your rhythm, even when you are on vacation.
A well-maintained irrigation system lasts for years. Flush the pipes regularly, protect against frost, and replace worn parts. I personally water for 15 minutes daily in the greenhouse and every three days outside – with a layer of mulch, that is more than enough.
I hope you consider it too, because after my greenhouse, this has without a doubt been my best garden investment ever.
Warm regards,
Tom
