Certified Backflow Testing for Commercial & Residential Properties
Protect Your Water Supply With Professional Backflow Testing
Your drinking water is one of the most important things we can help you protect. Backflow is a serious plumbing issue that occurs when contaminated water flows backward into your clean water supply — and most of the time, you’d never know it was happening. That’s why regular backflow preventer testing is so important, and why it’s required by law for most commercial properties in South Carolina.
At 1st Choice Plumbing, we are certified to perform backflow testing for both commercial and residential properties throughout Rock Hill, Fort Mill, Indian Land, York, Clover, Tega Cay, and Lake Wylie. When you need a licensed, trusted backflow tester in York County, make us your 1st choice.
What Is Backflow — and Why Is It Dangerous?
Under normal conditions, water in your plumbing system flows in one direction: from the municipal supply into your home or business. Backflow happens when that flow reverses, allowing water from irrigation systems, fire suppression lines, boilers, or other sources to push back into the clean water supply. This can introduce pesticides, fertilizers, bacteria, and other contaminants into the water that your family, employees, or customers drink and use every day.
A backflow prevention device is a valve installed in your plumbing system to stop this from happening. But like any mechanical device, it can wear out, stick, or fail over time — which is why routine testing is essential to confirm it’s working properly.
Do I Need Backflow Testing?
Commercial Properties: Most commercial properties in South Carolina — including restaurants, office buildings, medical facilities, schools, car washes, and properties with irrigation systems or fire sprinklers — are required by local ordinance to have their backflow prevention devices tested annually by a certified backflow tester. Failure to comply can result in fines or a water service shutoff.
Residential Properties: Homeowners with in-ground irrigation systems, pools, or auxiliary water connections are also typically required to have their backflow preventers tested each year. Even if testing isn’t mandated for your home, it’s a smart investment to protect your family’s health and avoid costly contamination issues.
If you’re not sure whether your property requires backflow testing, text or give us a call at 803-327-5555 and we’ll help you find out.
What Happens During a Backflow Test?
Our certified backflow testers will come to your property and perform a complete inspection and test of your backflow prevention device. Here’s what the process looks like:
- We locate your backflow preventer and check it for any visible damage or wear.
- We connect our test equipment to the device and run a series of pressure checks to verify it’s functioning correctly.
- If the device passes, we document the results and file the required report with your local water authority on your behalf.
- If the device fails, we’ll explain exactly what’s wrong, provide you with a clear repair or replacement quote, and get your system back in compliance quickly.
The whole process is fast, non-invasive, and typically takes less than an hour. We handle the paperwork so you don’t have to.
