Your Trusted Plumbing Partner

Our certified backflow testers ensure your systems comply with local regulations while protecting your water supply from contamination. Trust our experienced technicians to keep your backflow prevention devices functioning properly and your water safe for use.


Understanding Backflow Prevention

Backflow occurs when water flows in the opposite direction than intended in your plumbing system, potentially allowing contaminated water to enter your clean water supply. This dangerous situation can happen due to pressure changes in the water system, such as during water main breaks, fire hydrant use, or high demand periods.

Why Backflow Prevention Is Critical

Backflow prevention devices are essential safeguards that protect your drinking water from contamination. Without proper backflow prevention:

  • Contaminants, chemicals, and pollutants can enter your drinking water
  • Harmful bacteria and pathogens may infiltrate your water supply
  • Cross-connections between potable and non-potable water can create serious health hazards
  • Your property may fall out of compliance with local regulations and codes
  • You could face liability issues if contamination affects the public water supply


Common Backflow Hazards

Many everyday situations can create backflow hazards, including:

  • Irrigation and sprinkler systems
  • Swimming pools and spas
  • Water features and fountains
  • Fire sprinkler systems
  • Boilers and heating systems
  • Chemical dispensing equipment
  • Medical and dental equipment
  • Commercial kitchen equipment
  • Manufacturing processes
  • Car washes and pressure washers
