Jeff was outstanding! He was friendly, informative and efficient with his time while diagnosing and repairing a plumbing problem. He replaced my water regulator and shower cartridge. His work was meticulous and thorough. Pricing seemed fair and reasonable. This was my first experience with H20 plumbing and I won't hesitate to call again for future plumbing needs.
