A backflow preventer is a mechanical device that protects your water supply from contamination. It is installed on your plumbing system to stop dirty water from flowing backward into your clean water lines. That can include everything from irrigation runoff to commercial waste. Without it, you could be risking cross-contamination in your drinking water.
Whether you are managing a commercial property or just running a sprinkler system in your backyard, a backflow preventer keeps things safe and compliant. At One Call, we install and test these devices to make sure your water supply stays protected and your property stays in line with regulations.
In South Carolina, most cities and counties require a backflow preventer if your property has certain types of plumbing connections. That includes irrigation systems, fire suppression systems, restaurants, or any type of commercial plumbing. Local municipalities often have specific requirements for testing and certification.
If you are not sure whether your property needs one, we can take a look and give you a straight answer. If it is required, we will handle the installation, testing, and registration. You will not have to worry about paperwork or wondering if you are in compliance. We take care of it all.
Most backflow preventers need to be tested once a year. That is not just a suggestion. It is a legal requirement in many areas. Annual testing makes sure the internal components are working properly, especially the check valves and pressure relief mechanisms that stop contaminated water from backing up.
We are certified to test, repair, and replace all types of backflow preventers. If your device fails a test, we will either rebuild it or recommend a replacement depending on its condition. Some older devices wear out over time, especially in high-pressure commercial settings. We give honest recommendations based on what makes sense long term.
