Here is what we would be looking to buy to complete a garden watering system for patio pots and containers. We follow the plan and determine that we need 15 metres of supply pipe to run from the tap, past all of the containers and to the last plant pot. The garden tap is right next to the patio as well. Each pot contains just one plant each, and they are all roughly the same size and have roughly the same watering requirement. Scenario - We have a patio with 20 pots placed on it, and we want to water them whilst away on holiday. We want to avoid kinking the pipe, so it is important to consider using elbows whenever we have tight turns to install for. TOP TIP: If you need to run your pipe up and over a wall, consider planning for some extra elbow connectors to allow you to achieve this. Later in the guide, we talk about different types of configurations for different scenarios. We can also connect barb drippers directly to the main supply pipe if the pipe runs very close to the plant to be watered.Īll the components are available to buy separately, so you can easily customise how you want your system to be configured. We recommend having a maximum of 5 drippers connected to a single off shoot to ensure optimum performance of the drippers. We can also use inline drippers to make a chain of drippers on one off shoot from the main supply pipe. We do this for every plant we have, or if we have multiple plants close together, we can connect to the main supply pipe once, and then use Micro Tee connectors to branch off to multiple plants. The pipe used for this is either a 13mm or 19mm Irrigation Supply Pipe, an LDPE pipe that is UV and weather protected, is easy to cut to size and works in conjunction with 13mm or 19mm irrigation connectors, respectively.įrom this main supply pipe, we can branch off to 4mm Micro Supply Pipe to run to the plant to be watered. The path we have drawn represents the main supply route. This could be underground (up to 5cm), under mulch, hidden behind bushes, or neatly pinned to a wall or fence. Consider the best route for the pipework to follow to ensure it is out of sight. We ideally want the irrigation system to look neat and tidy, or better yet, hidden from sight. This path can do 90° turns around obstacles (using elbows) and can branch off in several paths (using tee connectors). With a scale map of your garden, draw a path from your water source past all the plants you wish to irrigate. To determine how much supply pipe we need for our drip irrigation system, we can draw on our map a route the pipe will take from the water source to your irrigation system’s endpoint(s).
