The Importance of Backflow Preventer Inspections
Backflow preventers protect potable water from contamination due to changes in water pressure that can cause contaminants to reverse flow into the clean water supply. Regular inspections are necessary for several reasons:
- Regulatory Compliance – New Jersey law requires periodic testing and certification of backflow preventers to meet NJDEP and local water authority standards.
- Preventing Water Contamination – A malfunctioning backflow preventer can allow chemicals, pesticides, and bacteria to enter the drinking water system.
- Protecting Public Health – Contaminated water poses serious health risks to homes, businesses, and public facilities.
- Avoiding Costly Repairs and Fines – Routine maintenance helps prevent costly breakdowns and penalties for non-compliance.
- Ensuring System Efficiency – Properly maintained backflow preventers contribute to the longevity and reliability of plumbing systems.
