Introduction
Backflow preventers stop reverse water flow that could carry pollutants into clean supply lines. Select models by pipe diameter, pressure rating, and local code requirements. Consider bronze or stainless bodies for corrosion resistance and accessible test for annual inspections.
- Double-check valve designs provide reliable protection in residential and light commercial systems.
- Reduced pressure zone units handle higher hazard levels where chemicals are present.
- Inline strainers capture debris that could impair valve seating over time.
Verify local plumbing codes before installing any backflow prevention device.
