Backflow Testing

Why Choose GS Plumbing?

Does your plumbing system have a backflow valve? What the heck is backflow, you may be asking? A back flow valve is a device installed on your commercial or industrial plumbing system designed to prevent water from flowing in the wrong direction, thereby protecting the city water supply from contaminants. Greenville County requires annual testing of all commercial and industrial back flow valves by a Greenville Utilities-certified tester. In addition, residential customers with new irrigation systems must be connected to a separate irrigation water meter.

Technicians from GS plumbing are not only certified but go through a re-certification process every two years. If you have received a notice about a back flow test or it’s time for your annual back flow test you can count on the professionals at GS Plumbing to handle the job for you.
