Backflow
Stay Compliant and Protect Your Water Supply with Certified Backflow Services
Backflow is a serious risk that can allow contaminated water to flow backward into your clean water supply—posing health hazards to your home, business, or community. At D.C. Home Service, we provide expert installation, repair, testing, and certification of backflow prevention devices for both residential and commercial properties throughout Southwest Florida.
What Is Backflow?
Backflow occurs when changes in water pressure (like a burst main or pump failure) cause contaminated water to reverse direction and enter your clean water system. This water may carry:
- Fertilizers or lawn chemicals
- Bacteria and waste from toilets or drains
- Industrial or commercial pollutants
- Dirty irrigation or sprinkler water
Local regulations require the installation and annual testing of backflow prevention devices to keep public and private water supplies safe.
