After we lost water pressure for all our water faucets, and our water supply company reported to us that there was no problem with water reaching our property, we called Culligan. Happy Culligan customers, we suspected that our water problem might be related to our Culligan system or the underground water supply to our Culligan system. Culligan San Marcos sent out their technician (Dustin) within two hours, he diagnosed the problem, and then worked diligently to fix it. Our Culligan water softener was functioning properly, but tree roots had broken an underground pipe coupling (about 40 inches below the surface), causing all water to flow into the ground. Dustin worked hard to fix this broken coupling (replacing it with a looping configuration of piping) and had the water again flowing to our house by mid-afternoon. Dustin showed himself to be a professional willing to go above-and-beyond. We love (and need) Culligan's soft water, and can attest to their excellent customer service also!
