C.O. Plumbing has been serving the San Gabriel Valley for over 30 years as a family-owned and operated plumbing company. From day one, we’ve focused on commercial and industrial plumbing, building long-term relationships with the businesses and communities we work with.

Over the years, our team has handled projects for all kinds of industries — bakeries, restaurants, animal hospitals, churches, and more. Every job has taught us that no two systems are exactly alike, and that’s why we take the time to understand the unique needs of each customer.

What sets us apart is simple: we care about doing the work the right way. Clean, precise, and professional has always been our standard, whether it’s a large installation, routine maintenance, or a complex repair. We know that when plumbing systems go down, businesses can’t run — so reliability is at the core of what we do.

At C.O. Plumbing, we’re proud of our roots and the reputation we’ve built. We’re not a big corporation — just a local family team who takes pride in keeping things flowing for the people and businesses in our community.
