What Is a Backflow?
Wastewater drains from your home into a sewer line or a septic system. There are two types of wastewater: gray and black. Water from sinks, showers, and washing machines is an example of graywater. Water from toilets and, occasionally, dishwashers is an example of blackwater. Backflow occurs when any contaminated water flows backward into the clean water supply. A backflow preventer is often the best solution if your system is susceptible to it.

The Causes of Backflow
The most common cause of backflow is a sudden drop in water pressure. This can occur due to a ruptured water main, backpressure from a pump, or unusually high water demand. Graywater or, even worse, blackwater, can contaminate drinking water without a preventer.
- Sewage
- Chemicals
- Pathogens
- Industrial waste
Backflow Prevention and System Testing
We can perform a comprehensive inspection and assessment if you don’t currently have a backflow preventer. If you need a preventer, we’ll help you choose the ideal solution for your property. We offer a wide range of high-quality backflow prevention systems. Backflow preventers essentially operate as one-way gates. Water can move in one direction, but it can’t flow back even if there’s a sudden loss of pressure or another issue.
Tuck & Howell also recommends regular backflow testing services. Commercial properties often require annual testing and certification, while residential properties should be tested every two to three years. Our team will ensure that your system is functioning properly and is compliant with all local regulations. When needed, our backflow services extend to correcting wear and tear, including cleaning and calibrating equipment and replacing parts.
Backflow Preventer Installation and Repair
You need a backflow preventer if you have drains flowing in the wrong direction. If you already have one, you’re likely experiencing problems with your current system. Our team performs routine inspections and maintenance that help avoid repairs. We complete all kinds of repairs, including full rebuilds, to adhere to all South Carolina building codes and manufacturer warranty requirements. Our company also handles new installations and replacements.
