What Is Backflow Testing?

Backflow testing involves checking the proper functioning of backflow prevention devices installed in your plumbing system. These devices are typically required in places where there’s a risk of contaminated water entering the clean water supply due to back pressure or back-siphonage. Our certified and skilled technicians perform these tests to make sure that these devices are operational and effective in preventing backflow.

For further information or to schedule backflow testing, feel free to reach out to us at City Base Plumbing. We’re committed to providing top-notch plumbing services with transparency and at competitive prices, ensuring your water systems are safe and compliant with local regulations.

Why is Backflow Testing Important?

At City Base Plumbing, we know how important it is to keep your water clean and safe. That’s why backflow testing is a key service we offer. Backflow testing stops harmful substances like chemicals, waste, and other pollutants from getting into your drinking water. This is not only important for your health but also required by law in many places, including San Antonio.

By testing regularly, we make sure that the devices that prevent backflow are working right. This helps avoid damage to your plumbing and keeps you from facing hefty repair bills. Most of all, it gives you peace of mind knowing that your water is protected and safe for everyone at home or at your business.

Easy as 1-2-3!

Backflow testing is a special check-up to make sure the water in your pipes doesn’t go backward and bring in dirt or harmful stuff from other sources.

Check Device

A backflow preventer stops water from going the wrong way in your pipes. During the test, we make sure this device is working right.

Turn off water

We turn off the water to see if the device can stop the reverse flow.

Give You The Results!

After checking, we write down how the device did. This report goes to the local water authorities to show that everything is safe.

City Base was quick and responsive when we called. When David arrived (exactly at the start of the repair window), he clearly explained the options I had for repair and the cost of each choice. He set straight to work to get it fixed and showed me the repair when completed. I really appreciate his hard work and honesty. 10/10

City Base Plumbing always responds quickly when we call them. David and Joseph have done two jobs for us and in both instances they did excellent work. They were very professional and helpful. Highly recommended!

J. Finely


Called City Base Plumbing off a recommendation from my neighbor. David and Joseph stopped by and fixed my issue quickly and efficiently. They were very professional and explained everything that they were doing, and they asked if it was okay to proceed, which I very much appreciated. Will definitely use their services if needed again.
