Installing a drip irrigation system

 

Installing our own drip irrigation system is very simple and will also save us time and money on damaged plants and poorly drained water. A drip irrigation system is the best solution to give accurate water to the plants of a terrace for example and is what we are going to treat.

A drip irrigation system will allow us to save up to 75 percent water, in addition to watering itself. In our store Abcbricoten.com you will find accessories and gardening kits with all the pieces and instructions, and the different elements separately. Make numbers and see what comes out more according to the characteristics and size of your terrace.

For a terrace of a surface of 10 to 50 square meters and basic necessities, that is to say, without different risks according to the examples, you will need:

• Polyethylene pipes. Two types are required: one of thicker section (12 to 16 mm in diameter), which functions as a main distribution pipe or circuit, and a thinner one (4.5 x 6.5 mm microtubes) to make bypasses or Branches that will carry water to each plant. They must be flexible, with a thin wall that allows to puncture the drippers. They are bought by rolls of 25 - 50 - 100 meters according to the dimensions of the terrace and the number of pots and plants.

Adjustable droppers. They are the valves of final distribution of water; Are connected to the microtubes by directly punching or engaging at their ends. And we have several types of adjustable drippers you can adjust the quantity supplied to each plant (0-7 l / h). And the standard dropper allow the passage of a fixed amount (2-4-8 l / h) of water.

Pressure regulator . It lowers and stabilizes the irrigation water pressure. It screws directly into the outlet of the faucet or water tap of the programmer. Some models incorporate self-cleaning filters that prevent impurities from passing water.

Programmer. It is a timer that is screwed to the faucet and regulates the passage of the water according to a schedule and frequency of irrigation. Must be specific for outdoor use and dispose of lithium batteries to avoid relying on the mains; Some include rain sensors to suspend irrigation in that case.

Accessories or links. They serve to splice the tubes, to derive, to divide and to adapt them to the surface of the terrace, and to carry the water to each plant. The most common are T, elbows, crosses and links, and should be chosen depending on the thickness of the tubes. If the drippers are of stake they are nailed directly to the earth; Otherwise, you will need fixing brackets: pickets for microtubes to nail them to the ground (two or three per planter, one per pot). If the self-locking system is online, not closed, a plug is required to close the end of the main tube (16 mm).

How many drippers and meters?

In order to obtain a regular flow in each dropper, it is not advisable to exceed 90 drops and 60 linear meters of pipe. Linear decks up to 100 meters can be installed, but a longer, more irregular length will result in irrigation. Many minutes pass since the programmer opens the valve and the water reaches the end of the system; The plants of the end will receive less water than the one planned by the programmer. In addition, the water will probably arrive with very little pressure.

To achieve a uniform irrigation it is better to use self-compensating drippers; The price difference is minimal, but allow the same flow rate to be supplied at different working pressures. They are essential, for example, when there are plants at different heights.

THE INSTALLATION STEP BY STEP

 

 Attach the controller to the water inlet, then screw in the Pressure Regulator.
 Insert the low density polyethylene pipe Ø 16 which will be the main one in the pressure regulator (can be fixed with clamps or Teflon tape) and extend it from the pots closest to the water outlet to the farthest one; Do not cut the tube over to the end. You can adapt the tube to the shape of the terrace by cutting and making joints with elbows. The main Ø 16 pipe should run alongside each container, following the designed layout. You can use links of T or cross to connect different sections or to derive a splice when there is a pot that is not in line.
3. Once the main tube has been extended, and all necessary connections have been made, cut the excess tube and place a plug (16 mm) at the end.

4. Once the main line has been installed, place the micro-tubes 4.5 x 6.5: with the aid of a punch (usually supplied together with the droppers) perforate the main tube at the height of each container and place a connector or link (T or cross) To fix the microtubes to the main pipe. Next, cut sections of microtube with enough length to reach each pot with slack (you can always cut, and it is better to make splices); Repeat the operation at the height of each planter.

5. Place the droppers along the microtubes (in the case of the planters) and at the ends of each (pots); Pinch the drippers on the ground if they are cutting, or fix them with securing pins.

6. It only remains to timer the programmer with the irrigation cycles. For the summer months it calculates an average of 10 to 20 minutes a day depending on the type of dropper (from 2 to 4 liters / hour).
