Backflow Testing Services

Serving South Bay & Orange County

Backflow from contaminated water can seep into your plumbing line if not properly maintained. At Stephens, we offer quality testing services to keep your water clean and your family safe.

Water Backflow Testing & Inspection Services

What is water backflow? This refers to dirt or other contaminated substances that find their way into your water supply because of water flowing in the reverse direction.

When dirt or chemicals enter your home’s plumbing, serious health risks can result. That’s why we use backflow testing to protect and test your water supply.

Call on Stephens’ experts to engage in backflow testing as a preliminary step if you suspect that your water may be contaminated. We’re happy to help!

Our experienced technicians will check valves for the correct pressure and use devices called air gaps to monitor water pressure. If we find that backflow is an issue, we’ll repair it. We can also perform regular preventative maintenance for you to ensure backflow doesn’t become an issue for you and your family.

Real Reviews From Happy Customers

Sort reviews

I worked with several contractors to diagnose and fix my AC Pro mini split units. Hundreds of dollars later and hours of frustration baking in the heat because of a non-working AC, Stephens was able to properly diagnose and fix my AC within days of calling them. Oscar, Omar, and Pancho are the best technicians with a wealth of knowledge. I called them for several different issues, and they have always been reliable, consistent, professional, friendly, and good at what they do! I know if I have a problem with my AC they'll get the job done. I am hard to please and id give them 10 stars if I could. Thank you Stephens Plumbing for doing an A++++ job!
