About Us

---

GCS Backflow Services was incorporated in early 2007 with the sole mission of protecting the drinking water supply of residents and businesses in greater Houston, Texas.

GCS focuses on the certification of backflow prevention devices for property managers, property owners, builders, plumbers, landscapers, and business owners.

We realize the backflow device is a "means to an end" for you. Whether your focus is on running your business, taking care of your residence, or closing out your construction project; the backflow device is not your focus. That is why GCS makes it simple for you.

Our Customer Service Director will schedule the visit around your needs. Our Texas Commission on Environmental Quality Backflow Prevention Assembly Tester Certified Technicians are experienced and efficient having performed thousands of tests and repairs.

Our Operations Team prides itself on working closely with the Water Provider to provide accurate and timely paperwork.
