Understanding Backflow

Backflow is a serious concern that can compromise the safety of your water supply. It occurs when contaminated water reverses its flow and enters clean water lines. This can happen at any cross-connection between clean and dirty water lines, often caused by significant changes in water pressure, such as burst water mains. The presence of hazardous materials like human waste, pesticides, or chemicals in the dirty water poses a severe health risk.

The Solution – Backflow Prevention Devices

Preventing backflow is essential for maintaining a clean water supply. Our expert technicians can install a backflow prevention device that acts as a safeguard against contamination. This device effectively stops contaminated water from entering your clean water supply, providing peace of mind for you and your customers.

The Importance of Regular Testing and Maintenance

Simply installing a backflow prevention device is not enough. To ensure its functionality and the continued safety of your water supply, regular testing and maintenance are crucial. Local municipalities require annual testing of backflow prevention devices to verify their proper operation. Failure to comply with testing requirements can result in fines and even a disruption of your water supply. Don’t take any chances – schedule your testing well ahead of time.
