Backflow Testing and Prevention-Protecting Your Drinking Water from Contamination
Ensuring the safety and purity of your drinking water is paramount, and backflow prevention plays a critical role in achieving this. In Charlotte, NC, and surrounding communities, local regulations require regular backflow testing for many commercial properties and some residential systems to prevent the contamination of the public water supply. At Osborne Plumbing & Drain, we specialize in comprehensive backflow testing, repair, and installation services, providing certified expertise to protect your home or business from hazardous backflow incidents.
Backflow occurs when contaminated water reverses its flow and enters the clean drinking water supply. This can happen due to changes in water pressure, such as a sudden drop in the main line or an increase in pressure from a private system. Our licensed and certified backflow specialists are dedicated to safeguarding your water quality and ensuring your property remains compliant with all local codes.

Understanding Backflow and Its Risks
Backflow is the undesirable reversal of flow of non-potable (non-drinking) water or other substances into the potable (drinking) water system. This can introduce a variety of contaminants, including:
- Chemicals: From irrigation systems, industrial processes, or cleaning solutions.
- Fertilizers and Pesticides: From lawn sprinkler systems.
- Human Waste: From sewer lines or septic systems.
- Bacteria and Viruses: From various sources, posing serious health risks.
Common scenarios that can cause backflow include:
- Backpressure: When the pressure in a private system (e.g., a boiler, a pump, or an elevated tank) exceeds the pressure in the public water supply.
- Backsiphonage: When a sudden drop in pressure in the public water main (e.g., due to a burst pipe or heavy water demand) creates a vacuum that siphons contaminated water back into the clean supply.
Backflow prevention devices are designed to stop this reversal of flow, acting as a critical barrier between contaminated sources and your drinking water.
