Certified Backflow Testing and Repair Specialists

Protecting Maine's drinking water one backflow at a time

Our Services

Commercial & Residential Backflow Testing

By law backflow testing must only be performed by certified backflow testers. Our technicians are certified to test backflow assembly devices throughout the state of Maine by the New England Water Works Association. We are dedicated to performing accurate and honest backflow testing to ensure our clients’ water is safe.


Backflow Repairing

Maintaining the proper operation of backflows is extremely important to protecting the drinking water systems in Maine. We take that responsibility serious when it comes to repairing a faulty backflow. Whether your backflow has failed its regular testing or is leaking for no explained reason we will take the time necessary to diagnose and repair the problem. Our goal, whenever repairing a backflow prevention assembly, is to return that assembly back to factory specifications so that assembly will continue to protect your drinking water from possible contamination.
