With a 33 ft long drip line, 25 drip points that can be installed at any distance from each other (the drip line is cut and each drip point installed selectively), a number of "T" junctions and end stops, this is a kit that can be custom assembled by the user. Tiny, in-line valves allow for watering isolated zones, and staggered schedules. The Kit also comes with a pressure regulator and connectors for standard (GHT) garden hose bib and a Quick-Change hose fitting.
Joining connectors are provided to allow you to serially connect kits together to operate off the same water source. It's all thoughtfully designed, inexpensive, and very easy to use to maximum benefit. Highly recommended. Two year manufacturer's warranty.
