Landscape Dripline
TECH SPECS
Introducing the
Next Generation
of Inline Tubing

Next Generation Technology Delivers Unmatched Performance
Rain Bird Landscape Dripline is the next generation in pressure-compensating, inline emitter tubing. It delivers unmatched clog resistance for long-term reliability. Its patented design eliminates the need to install an air relief valve or an automatic flush valve on each inline tubing station when the tubing is installed at grade and mulched over. This will save installation time and expense whenever you specify or install Landscape Dripline instead of today's most popular inline tubing. When you combine Landscape Dripline with Rain Bird's comprehensive line of Turf and Xerigation drip products, you'll have the peace of mind and confidence that can only come from specifying and/or installing a complete Rain Bird irrigation system.

Features

•  The brown color of Landscape Dripline blends in with the non-turf landscape and/or mulch. The product picture above with clear tubing is intended for illustration purposes only.
•  Pressure compensation ensures consistent flow from each inline emitter throughout the entire length of the tubing run.
•  Choice of flows, spacing and coil lengths provides design flexibility for a variety of non-turfgrass applications.
•  Rain Bird's patented ADI emitter (Advanced Drip Inline) pressure compensates by "lengthening" the emitter's turbulent flow path instead of reducing the cross-sectional area of the emitter's flow path. The result is unsurpassed clog-resistance over the long term.
•  Cylindrical shape of Rain Bird's ADI emitter "welds" to the inner circumference of the polyethylene tubing, creating a physical barrier that keeps the emitter cover and silicone wafer securely in place even when tubing is kinked in the field.
•  Cylindrical design of Rain Bird's ADI emitter provides surface area for filtration throughout 360° of its outer circumference. This superior filtration, combined with ADI emitter technology, eliminates the need to install an automatic flush valve in the station - saving both time and money.
•  The dual outlet ports on every Rain Bird inline emitter act in combination as a micro air relief valve--eliminating the need to install a separate air relief valve at the highest point of the inline tubing. This applies when tubing is installed at grade and mulched over.

Pressure Compensation Without Reducing Size Of Emitter Flow Path

Rain Bird's Landscape Dripline pressure compensates unlike any other inline tubing in the world. Using its patented ADI (Advanced Drip Inline) technology, pressure compensation is accomplished without ever reducing the cross-sectional area of the emitter flow path. That means the size of the flow path never gets smaller as the pressure increases. At higher pressures, the cross sectional area of Rain Bird's ADI emitter now path is nearly ten times greater than the cross-sectional area of today's most commonly specified pressure-compensating inline emitter.

Anatomy of a Clog-resistant Inline Emitter:

How the ADI Emitter Works

At pressures under 8 psi, Rain Bird's ADI emitter is in the self-flush mode. Water flows freely around and through the labyrinth inside the pressure-compensating chamber of the emitter. Any contaminant inside the emitter is flushed through the emitter outlets. This self-flushing mode occurs at the beginning and at the end of every watering cycle to assure long-term reliability.

Self-Flushing Mode:

Patented ADI Technology "Lengthens" Flow Path

As the pressure increases, the silicone membrane in the ADI emitter's pressure compensating chamber begins to compress against the emitter's sloped labyrinth which is also located inside the emitter's pressure compensating chamber. This compression "lengthens" the torturous path through which the water must pass by channeling the water through more and more of the sloped labyrinth as the pressure increases.

Compensation Mode At Lower Pressures

At Higher Pressures, ADI Technology "Lengthens" Flow Path Even More

As the pressure continues to increase, the silicone membrane continues to compress longitudinally against the emitter's sloped labyrinth. This forces the water to pass through more of the labyrinth. As the water travels through this "lengthened" torturous flow path, a metered pressure drop is created that results in pressure compensation from 8-60 psi. Because the cross-sectional area of the flow path is never reduced, the ADI emitter's flow path has a cross-sectional area that is nearly ten times greater than that of a conventional pressure-compensating inline emitter. The benefit? Increased clog resistance over the long term.

Compensation Mode At Higher Pressures:

Cylindrical Emitter Design Delivers Unique Advantages

The shape of Rain Bird's ADI emitter is cylindrical. This means the ADI emitter can be "welded" securely in place to the inner circumference of the polyethylene tubing via a physical barrier over the ADI emitter cover. Should the inline tubing be inadvertently kinked in the field during installation, the cover and wafer won't be dislodged the way the covers and wafers of conventional inline emitters can be dislodged.

More Emitter Surface Area Means More Filtration Area

Another advantage to the cylindrical shape is increased surface area. By its very geometry, the ADI emitter has much greater surface area than a conventional inline emitter. This additional surface area, when used for filtration, means longer term clog-resistance. Whether there's a break in the line, an unforeseen problem with the main filter or just an unusually high presence of sediment; more filtration surface area is better than less filtration surface area. And with Rain Bird's Landscape Dripline, each ADI emitter provides more than five times the filtration area of conventional inline emitters.

Greater Surface Area Means More Filtration:
