Rain Bird XFS-CV Subsurface Check Valve Dripline 0.9 GPH 18 in. Spacing 500 ft. (Sold per Roll)

Rain Bird XFS-CV Dripline with an improved 4.3 PSI check valve delivers 10 feet of hold-back – the highest in the industry. With pure copper chips in every emitter to protect against emitter root intrusion, XFS-CV dripline is an all-in-one dripline suitable for any application – on-surface, sub-surface, sloped or level-grade. When used in applications where elevation changes exist, the patent-pending check valve keeps the dripline charged with water, delivering better irrigation uniformity while preventing over-watering and puddling at the low-point in the zone.
