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. Our plumbers are available in your area and are fully qualified to inspect, test, and repair all backflow assemblies and devices. Learn more about commercial preventative maintenance programs.

Mike & Betty Welker

When I called, the response was quick and thorough.

I was pleased with the service and the repairman as well as the end result. The repair took a total of 4 trips due to added problems which were all resolved at no extra expense to me. I was also pleased that the additional appointments were worked around my work schedule. Thank you for being respectful of my time and for your commitment to getting the job done right.

G.P.

The man that replaced my hot water heater was fast, professional, competent, and thorough.

He took the old hot water heater out of my basement without almost any effort. He was really good and seemed like he really knew what he was doing. I have already recommended Dauenhauer to others.
