Make connecting irrigation pipes easier

When connecting poly pipe for irrigation projects, like installing pop-up sprinklers or water features, soak your pipe ends in hot water. This will soften them and let you mould the ends to suit the fittings that join the pipes together.

Step by Step Instructions

1 Lay poly pipe to attach sprayers
2 Attach a sprinkler with flexi tube and adapter
3 Attach a sprinkler without a stake
4 Attach the flexi tube and adapters to the sprinkler
5 Roll out poly pipe for drip system
6 Punch holes
7 Cut flexi tube to size
8 Attach adapters and drippers to the flexi tube
9 Install a drip line
10 Join drip lines
11 Join the drip line to the dripper system
12 Attach the whole system to a garden tap
  • Step 1. Lay poly pipe to attach sprayers

    Measure and cut the poly pipe and pin it to the ground. Sprayers are good in hot houses and vegetable patches. They’re not so good in shrubbery. There are many different types of sprayers. Some will have flexi tube and a riser already attached. For other types you will have to attach these yourself.

  • Step 2. Attach a sprinkler with flexi tube and adapter

    First we demonstrate how to attach a sprinkler with a flexi tube and a 4ml adapter already attached. Use a hole punch to punch a hole in the poly pipe and push the 4ml adapter into the pipe. Put the stake of the sprinkler into the ground where you would like the sprayer to spray.
  • Step 3. Attach a sprinkler without a stake

    To install a sprinkler that’s not on a stake, you will need to attach it to a metal riser to install it. In this demonstration the sprinkler is attached to a 4ml adapter. Connect the adapter to the pipe in the same way as in Step 2.  Place the metal riser in the correct position for the sprayer
  • Step 4. Attach the flexi tube and adapters to the sprinkler

    Installing your own flexi tube gives you more flexibility on how far you want your sprayer to be from your plants. First snap the 4ml adapter off the sprinkler. Cut the flexi tube to length. Attach one end to the sprinkler and the other end into the 4ml adapter. Pre-punch a hole into your pipe and attach adapter to the pipeline. Put sprayer in place.
  • Step 5. Roll out poly pipe for drip system

    Use a drip line system when installing individual dippers. First roll out poly pipe and measure and cut. It is easier to roll the pipe out on the lawn where easier to work with. Lay the pipe in the garden and pin it in place.
  • Step 6. Punch holes

    Use your hole puncher to individually punch a hole behind each plant. Make sure the hole is on the side of the tube facing toward the plant.
  • Step 7. Cut flexi tube to size

    Cut the flexi tube to size. Measure each piece to the right length by holding one end to the pipe and the other to the plant. Cut a piece of flexi tube for each hole that you’ve made in the pipe.
  • Step 8. Attach adapters and drippers to the flexi tube

    Attach double end adapters by placing one end into the flex tube and other into the pipe. Then attach the dippers on the other end of the flexi tube. Make sure the holes in the pipe are coming out the side. Place the dripper next to the base of the plant.
  • Step 9. Install a drip line

    Drip lines are perfect along hedges. They are easy to install because they already have perforated holes along the piping. There is nothing to attach. Measure lengths and cut to size. Pin down the pipe of drip line in your garden.
  • Step 10. Join drip lines

    To attach drip lines to each other, you’ll need a 13ml elbow and 13ml locking clamps. Dip the ends of the drip line pipe in hot water to make them more flexible and pliable so you can get the fittings in easily. Run the remaining drip line around hedges. At the end of your drip line put in an end cap. Push it into the line and use a hammer to push it in securely.
  • Step 11. Join the drip line to the dripper system

    In this example we attach the drip line system to the dripper system laid earlier. You need a 19 - 13ml reducer and 19 - 13ml lock and clamp. Attach the 13ml pipe to 13ml end and the 19ml pipe to 19ml end.  
  • Step 12. Attach the whole system to a garden tap

    Attach the whole irrigation system to the garden tap. You will need a 19ml snap on connector. Test the system and make sure everything is in good working order.
