What is “backflow”?
Backflow refers to the unwanted reversal of the flow of water or other substances through a cross-connection into the piping of the potable water supply. This reversal can cause contamination and pose serious health risks if pollutants, chemicals, or untreated water enter the clean water supply.
When reverse flow occurs in plumbing pipes, chemicals, pesticides or other contaminants can find its way into the drinking or potable water supply. Establishments located near agriculture or heavy industry may be more likely to experience backflow issues and water contamination.
Backflow typically occurs due to two main reasons:
- Backpressure: This happens when the pressure in the downstream piping system exceeds the pressure in the supply system. Common causes include pumps, elevated tanks, or boilers creating higher pressure.
- Back siphonage: This occurs when there is a negative or reduced pressure in the supply piping. This can happen during events like water main breaks, firefighting, or when a large amount of water is withdrawn, creating a siphon effect.
If you own a property that is located near possible sources of pollution, it’s very important to have the best possible backflow prevention device installed. If your commercial business already has a backflow prevention system, always make sure to have it inspected once every 12 months to ensure everything is working properly.
Risks and Consequences
Contamination: Pollutants such as chemicals, pesticides, or sewage can enter the clean water supply, posing health risks.
Health Hazards: Consuming contaminated water can lead to various illnesses, including gastrointestinal diseases and infections.
Damage to Plumbing: Contaminants can cause corrosion or damage to the plumbing infrastructure.
Backflow can pose a serious health risk to both employees and customers. If left unresolved, backflow can contaminate fresh water sources and cause serious illness. A business that provides drinking water is required by law to prevent possible cross-contamination due to backflow.
Some businesses that should consider upgrading or inspecting their current backflow prevention devices are spas, water parks, restaurants or hotels.
Prevention Measures
To prevent backflow, several measures can be implemented:
- Backflow Prevention Devices: Installing devices such as backflow preventers, check valves, and air gaps can help prevent backflow. These devices are designed to allow water to flow in one direction only.
- Regular Maintenance and Testing: Ensure that backflow prevention devices are regularly inspected and tested by qualified professionals to ensure they are functioning correctly.
- Cross-Connection Control Programs: Implementing comprehensive cross-connection control programs to identify and manage potential cross-connections in the plumbing system.
Legal Requirements
WA law now requires that a backflow prevention device be installed in all commercial properties and businesses that are open to the public. Upon installation, a backflow prevention device must be tested for consistency and then inspected at least once every six months.
