Chris and Lorenzo came out hella fast to fix the pipes underneath my sink in the kitchen. A massive leak, that I didn’t notice till it was too late. They were professional, gave the best customer service I could have asked for. They made the experience quick, hilarious and educational when they walked me through…

Our 80 year old sewer line needed to be replaced. We contacted three plumbing companies which had the required State of California licenses. One of the companies that we contacted was Economy Plumbing. Spencer Lei was the technician who responded. We would normally refer to Spencer as a plumber. However, he had such modern equipment, including video cameras and trench-less digging equipment, we refer to him as a Technician, who specializes in plumbing. We had anticipated that our garage, side walk, and street would have had to be torn up, for several weeks. We were misinformed by one of the plumbing firms that we could not park vehicles in our garage for two weeks, as our street, side walk, and garage would all have to be torn up. Spencer assured us that only a small hole would be dug in the street, to accommodate the new pipe. The entire project was completed in two day. Spencer and the entire staff was responsive, courteous, and professional at all times.

Adam was great! He arrived within the scheduled appointment window to provide us with an estimate. He was very friendly, professional, and took the time to clearly explain the issue with our leaking water pressure regulator and what needed to be done to fix it.
They were able to repair the leak the same day, which was greatly appreciated. We are very happy with the service and would definitely recommend Adam and Economy Plumbing to our family and friends.
Thank you, Adam, for your excellent service!
