Our supplied Pressure Compensating Dripline tubing comprises of 100’ and 250’ rolls of dripline along with 1-GPH pressure compensating (PC) drip emitters that are built into the interior wall of the dripline every 12” and 18”. Each of the PC drip emitters comprises a cylinder along with a labyrinth-like water passage, silicon diaphragm, and a filter. Each PC drip emitter continuously adjusts to the varying incoming water pressures which range from 10 to 45 PSI that ensures a constant flow rate without any regard of any elevation along the dripline. Adding to that, the self-flushing mode of the drip emitter allows particles to pass harmlessly through and offers reliable performance with long service life. For residential and commercial applications, you can install this drip line above the ground and if required, you can cover it with mulch for blending with the landscape. The PC dripline is ideal for plants in preset spacing, closely spaced pants in rows, narrow planting along with groundcover, hedges, roses, and shrubs. For complete coverage of an area, you must use several dripline lines, placing the lines at a distance of 16 to 24 inches. Adding to that, the dripline can be used around a house foundation for reducing the movement of soil, slab, and cracking damage.
