The underground drip pipe with a diameter of 13.7 mm is installed invisibly in the ground and is used for the irrigation of border plantings and lawns. Drippers are built into the pipe every 30 cm, each providing a finely dosed irrigation of 1.6 l/h. The drippers are self-closing, ensuring they do not get contaminated after decommissioning. To prevent roots from penetrating the underground pipe, the drippers are equipped with a root barrier. The water pressure is consistent at every point along the drip pipe to ensure uniform irrigation. The drip pipe is an extension set for item no. 257030, it comes with a connector and an end piece and is 50 m long.
