I had a great experience with Cupertino Plumbing. The staff came out to change the water pressure regulator in the incoming pipes. They did the job quickly, cleanly, and efficiently. The pricing was a bit high, but it was definitely worth the cost. It was the first time I used them, but they still did a great job and I would recommend them to other people. I would use them again if I ever needed a similar service in the future. The staff was great, they know what they're doing, and they came in on time. They use quality parts, good procedures, and there's not much more that you could ask for.
