Landscape Dripline is a closed-loop grid of inline emitter tubing that, when
properly spaced, delivers full coverage to a planting area (see Figure 5-1). The
soil type and planting scheme influence which flow rate, emitter/lateral spacing,
length of lateral and configuration you choose. Landscape Dripline is easy to
install and maintain because:
• Built-in pressure compensation ensures consistent flow from each inline
emitter throughout the entire length of the tubing and throughout its
8 - 60 PSI (0,5 - 4,0 Bars) operating range.
• Rain Bird's patented inline emitter pressure compensates by effectively
lengthening the flow path instead of reducing its size. This significantly
increases its clog resistance.
• Dual exit ports for each emitter act like built in micro air relief valves.
When combined with the inline emitter’s cylindrical design, the need for,
and cost of, installing air relief valves and automatic flush valves is
eliminated. This is the case whenever the tubing is installed at grade or
in a 1" - 2" (25 - 50 mm) deep trough and then mulched over. However,
when installing Landscape Dripline subsurface in a non-grass applica-
tion, install air relief valves at the highest points of the closed-loop grid.
• You can use compression or insert fittings to install.
• You can add emitters to the grid to water individual plants.
