" Eddy arrived on time. He gave a reasonable estimate for the external valve replacement. Two valves were replaced: one for the mains and another for irrigation. The job was well done and quite fast. He also replaced the holder for the sediment filter which is upstream from the water softener. I would hire him for any future plumbing needs."
