Backflow Testing & Prevention Nationwide
Captain Backflow helps commercial premises across the UK prevent backflow and stay compliant with water regulations. From identifying the risk to installing and testing the right prevention device, we provide a complete backflow service.
Understanding backflow
Backflow happens when water flows in the wrong direction — from a property's system back into the public mains supply. This can pull contaminants, chemicals or bacteria into the drinking water supply, creating a serious health hazard.
UK water regulations require commercial premises to have appropriate backflow protection based on the level of risk. Captain Backflow assesses your premises, installs the correct prevention device and tests it annually to keep your supply protected.
