IrriGRAY 2.2 GPH is designed for landscape bed and planter grawyater irrigation. The fast drip rate allows sufficient flow rate to acheive 5 gallons per minute flow rate with 150' of dripperline.
 
For IrriGRAY Graywater Systems, the optimum total length of dripperline is between 150' and 300'. 
 
We recommend a maximum lateral length (supply from one end only) is 60'. Refer to the Irrigation section of the IrriGRAY User & Installation Guide, in our document library.
