1.2.1 To perform a test run
Before installing the irrigation system below ground, we recommend that you carry out a test run
above ground:
1. Lay out the irrigation system above ground.
2. Cut the connecting pipes to the required length.
3. Install the irrigation system above ground.
4. Open the water supply to check the irrigation system for leaks.
If the irrigation system is tight , you can install it below ground.
If the irrigation system is not tight , check that all connections are made correctly, e.g. that the con-
necting pipes are inserted into the connectors as far as they will go.
