Protecting the integrity of the public water supply is a critical responsibility, and backflow prevention is the mechanism that ensures our drinking water remains safe and uncontaminated. Backflow occurs when a sudden drop in municipal water pressure—such as during a major water main break or when fire hydrants are heavily utilized—creates a vacuum effect. This vacuum can physically siphon dirty, contaminated water from commercial properties, irrigation systems, or industrial processes backward into the clean, public drinking water lines.
To prevent this dangerous reversal of flow, municipalities strictly enforce the installation and annual testing of mechanical backflow prevention devices. The City of London has stringent bylaws requiring specific commercial, industrial, and multi-residential properties to maintain certified backflow preventers. Failure to comply with these regulations can result in severe municipal fines, liability issues, and even the complete termination of your property’s water service.
Our team features fully certified and registered backflow technicians authorized to perform mandatory annual testing in the London area. We handle the entire compliance process for you. We arrive on-site, perform the rigorous pressure tests required to ensure the internal check valves are sealing perfectly, and submit all necessary certification paperwork directly to the local water authority on your behalf, keeping your property fully compliant without any administrative hassle.
If a backflow preventer fails its annual test, immediate action is required. Because we are full-service plumbers, we do not just test the devices; we are fully equipped to tear them down, clean the internal components, replace worn rubber seals, and restore the unit to perfect working order. If the device is beyond repair, we can immediately supply and install a brand-new, code-compliant assembly.
We also design and install custom backflow prevention systems for new construction projects, major renovations, and properties upgrading their water service. Whether you are managing a large commercial facility, a restaurant, or an agricultural operation, our certified experts provide the specialized testing and maintenance required to protect your business, the environment, and the health of the community.
