Where to Buy

Key Features

  • Converts a sprinkler riser into a multi-outlet, low-flow drip irrigation emitter
  • Barbed swivel outlets enable tubing to be positioned where desired
  • Each outlet has an individually adjustable discharge rate from 0 to 20 GPH; turn dial with coin or flathead screwdriver to adjust rate
  • Built-in removable filter helps prevent clogging and can be cleaned to extend system lifespan
  • Designed to work with standard drip irrigation water pressures up to 50 PSI

Applications

  • Converts an underground sprinkler system to a micro irrigation drip system that waters multiple plants and with  various flow rates
  • Ideal for landscaped perimeters and garden areas; can be used above grade or below grade in an emitter access box
  • As part of a complete drip system, the bubbler delivers low volume irrigation to the plant’s root zone; with a non-pressure compensating emitter, the longer the run the lower the volume of output as water travels further away from the water source

Installation & Maintenance

  • Connect the 1/2 in. FPT inlet to a 1/2 in. MPT connection point on an underground sprinkler riser; barbed outlets connect to 1/4 in. distribution tubing (A220 and A250) or 1/4 in. Dura Flo™ JR dripline
  • Periodically check for leaks or damage and repair as needed; recommended operating pressure for most emitters is up to 50 PSI

Materials & Sustainability

  • Emitter made of Acrylonitrile Butadiene Styrene (ABS) treated with UV inhibitors to prevent fading and cracking
  • Made in the USA
  • Drip irrigation can reduce water usage by up to 70% compared to conventional sprinkler irrigation when used properly; for most drip irrigation products, water is applied precisely and at the rate the soil can accept it to prevent runoff and erosion
