Look for rigid PVC pipe or drip tubing when choosing irrigation piping.
Unless you plant only native species, proper irrigation will be critical in keeping
your waterwise landscape happy and healthy. All irrigation systems start with piping,
either rigid pipe or flexible tubes. Most residential sprinkler pipe is made from
PVC (polyvinylchloride) and comes in a variety of sizes, from ½-inch on up. To take
piping around bends and corners, you’ll also need a variety of joint fittings—short,
angled pieces that either screw together or can be welded with pipe glue. Ask your
irrigation dealer for advice in choosing appropriate piping for your system.
Valves, another essential irrigation component, act as on/off switches, allowing
landscapes to be divided into planting zones with different water needs and irrigated
accordingly. With a programmable controller, valves will open and shut automatically
according to preset schedules.
Pipe fittings can be screwed together or welded with pipe glue. Most drip tubing simply pops into place.
Water is released to plants, trees and lawns through emitters and sprinkler heads,
which come in a variety of types and sizes to optimize efficiency and meet specific
watering needs. Finally, every irrigation system should include a backflow prevention
device, required by law in most cities, to keep irrigation water from seeping backwards
into your home.
||Typical drip lines are ½ inch in diameter and supplemented by tiny spaghetti tubes.
