Backflow occurs when contaminated water flows back through a pipe into a potable water source, rendering it undrinkable. Backflow can happen if there is not sufficient pressure in the pipe to keep the water flowing properly. To prevent drinking water from being contaminated through backflow, a backflow prevention system must be installed. This type of system prevents a potable water system from coming into contact with contaminated water.
Backflow Prevention Regulations
Many cities require that all commercial buildings be outfitted with backflow preventers. Typically these systems must be inspected and maintained each year to ensure that they are in good working order. As long as backflow preventers operate properly, clean drinking water will continue to flow properly from the water source to the faucet, keeping it safe to drink. When a backflow prevention system malfunctions or fails, however, water may begin to flow backwards through the system, contaminating the water and possibly making people sick. This is why it is crucial to consistently maintain a backflow preventer.
Maintenance and Repairs
Backflow prevention is accomplished by keeping an air gap in the pipe or by installing a mechanical obstacle that prevents backflow. A check valve is commonly used as a mechanical backflow prevention device. This valve only allows water to flow one way through the device, thereby preventing the problem of backflow altogether. However, sometimes these valves can be defective or can begin to leak over time. An experienced backflow prevention company that specializes in maintenance and repairs can help you to keep your prevention system in good working order.
