The WVI system was in place when we bought our home. They attended and re-activated it for us, including some minor repairs. It has since saved us enormous time vs. hand-watering the many beds, baskets, etc. in addition to our lawns. WVI have been very responsive & technically competent in attending to assist us with minor issues, including programming the control box to meet legalities and our watering needs. We are fully satisfied with the service received.
