Protecting Your Water Supply with Expert Backflow Prevention

At B Wagner Contracting, we specialize in backflow prevention and testing services to ensure your home or business has a clean, safe, and reliable water supply. Backflow can introduce harmful contaminants into your potable water system, posing health risks and potential plumbing code violations. Our certified team provides professional testing, installation, and repair services to keep your water system in compliance and operating efficiently.
What is Backflow?
Backflow occurs when contaminated water flows in the reverse direction, entering your clean water supply due to pressure changes in the system. This can happen due to:
Back Pressure: When water pressure from a non-potable source exceeds the pressure in the clean water line.
Back Siphonage: When a sudden drop in pressure (e.g., water main break, firefighting) causes contaminated water to be pulled back into the supply line.
Without proper prevention measures, backflow can introduce pollutants, chemicals, or bacteria into your water system, creating serious health hazards.
