Why Maintenance Matters in New Jersey
With NJ’s cold winters, saltwater air (near the shore), and strict township codes, preventers here face more challenges than most areas. A neglected device can fail a test, freeze and rupture, or even become a legal liability.
We regularly see damage caused by:
- Improper or missing insulation
- Long-term mineral buildup from hard water
- Skipped maintenance on older RPZ models
- Incorrect part replacements
- Poorly sealed or broken enclosures
Regular care not only prevents failure—it also saves money, avoids emergency calls, and extends the usable life of your backflow system.
