Fabricio de Araujo is the owner of ValleyTask, a Livermore-based irrigation and landscape crew that has looked after Tri-Valley yards since 2003. ValleyTask's specialty is the work most crews avoid: valves, controllers, drip and sprinkler systems, from quick repairs to full installs. The crew also handles mowing, lawn care, seasonal cleanups and weed abatement for homes and acreage across Livermore, Pleasanton, Dublin, San Ramon and Danville. What Fabricio writes here comes from those jobs: what actually breaks in Tri-Valley yards, how to spot it early, and when it is worth calling a pro.
