Backflow Prevention: Protecting Our Water Supply

At Bay City Plumbing in Hervey Bay, we provide expert backflow prevention to protect your property and drinking water. Backflow occurs when water reverses direction, potentially contaminating the supply. Essential backflow prevention devices ensure contaminants cannot enter the town's drinking water system.


How Backflow Occurs

Backflow can be caused by two primary factors:


  • Back Pressure: Increased pressure in your plumbing pushes water the wrong way.
  • Back Siphonage: A drop in water supply pressure causes contaminated water to flow back.


When You Need a Backflow Prevention Device
Backflow devices may be required if you have:


  • Irrigation systems or fire hose reels
  • Commercial machinery connected to mains water
  • Water outlets near pollutants or grease traps
  • Underground rainwater tanks with mains backup
  • Black/greywater dump points or bidets (manufacturer-specified)
