Backflow Certification


Backflow prevention systems have been mandated by the EPA, (Clean Water Act of 1987), to safeguard the drinking water supply in our communities. Services related to this critical area involve specifying, installing and repairing all types of backflow devices.  The maintenance of backflow systems can seem daunting and difficult to manage, but to ensure you meet EPA requirements, DeFranco Plumbing will send all official backflow certification forms to the appropriate agency, and send you annual notices for re-certification, as a service to clients.  Service technicians undergo advanced training for the latest technology in backflow prevention which makes DeFranco Plumbing a leading backflow prevention and certification contractor in the Chicagoland area.
