May be hung on a wire, laid on the ground or buried, making it an economical choice for vineyards, orchards, and row crops.As with our blank poly tubing, additional PC emitters and/or 1/4" micro line can be added to this drip line. When adding additional drippers, do not punch too close to the pre-installed emitters and take care not to exceed the maximum flow rate for the specifications and run length. For optimal operation we recommend not exceeding 200 ft per run. Keep in mind that operating pressure and emitter spacing can affect the optimal operation and run length recommendations. Lower pressure and closer emitter spacing would perform better at shorter run lengths. If using higher operating pressure and wider emitter spacing you can achieve consistent emitter flow rate in some longer runs. Keep in mind that uneven terrain and varying environmental factors may affect the operation as well.Very effective method to irrigate crops in difficult topographical conditions, low and varying water pressures and where longer laterals are required. This drip line is compatible with our 1/2" Perma-Loc fittings. Do to the tightness the tubing must be rolled it often has a more oval shape when first opening a new roll. There also may be some slight kinking in the center of the roll and where the banding is, this will not hinder the use and performance of the tubing. These issues will smooth out after un-banding and some sun exposure and the ovalness will round out over time or with a few uses (pressurization/depressurization).Features:Built-in filtration provides superior clog resistanceLarge turbulent flow path allows particles to pass freelyConsistent discharge over a pressure range of 7 - 60 PSICV (coefficient of variation) values Style : Emitter Spacing 12" UnitCount : 1 UnspscCode : 56101600
