Irrigation units must be connected using a system that ensures perfect alignment with the soil, even months and years after installation. A sprinkler head that “sticks out” of the ground is a potential hazard for passers-by, an easy target for vandalism (as it is so visible) and a perfect test for the durability and sharpness of lawnmower blades.

The installation of the system is crucial for perfect functioning over its entire working life: it may be true that these are only “buried plastic tubes”, but they have to be buried at the right depth, following a precisely designed plan and connected using specific fittings of the correct type and dimensions.

The flow rate of water within the tubes must be kept low, to eliminate head loss which would otherwise affect the functioning of the sprinklers. With the same flow rate, a larger-diameter tube may remove the need for a pump, with the resulting energy savings.
