Keep Your Commercial Facility Compliant. A backflow prevention assembly prevents the water in your system from flowing back into the public water system.
In a commercial or industrial building, the backflow assembly should be tested annually to ensure the safety of our drinking water.
A failed building inspection can cost you much more than the cost of getting a backflow installed properly and tested regularly.
The Kentucky State Plumbing Code requires backflow preventers to be installed in all commercial buildings. This protects the community water supply from contamination and pollution. Annual backflow testing for Kentucky commercial facilities must be completed by a certified backflow tester.
The results are then reported to the municipal water company; MSD in Louisville and Kentucky-American Water in Lexington. If your building needs a backflow preventer installed, this will require a permit issued to a Master Plumber and installation performed by a Journeyman Plumber, followed by inspection and certification.
At Dauenhauer Plumbing Heating & Air, we have licensed, professional plumbing technicians to perform this work for your commercial building, and to ensure your inspections and certifications stay up-to-date each year.
Dauenhauer Plumbing Heating & Air offers scheduled or emergency backflow testing, repair, and installation services.
