How often is backflow testing required?
Most water utilities require testable backflow assemblies to be tested at installation and then annually, with the results filed by a certified tester. Requirements and filing methods vary by utility, including Greater Cincinnati Water Works, Northern Kentucky Water District and municipal systems, so follow the notice your utility sends.
Backflow preventer installation and repair
If a device fails its test, it usually needs new internal parts, such as check valves, springs or seals, and a retest. New devices are required when you add irrigation, a fire line or certain commercial equipment. A licensed plumber can install the right type of assembly for the hazard level.
Do I need a water softener in Cincinnati?
Much of Greater Cincinnati has moderately hard to hard water, and some well and municipal systems north of the city are harder still. A softener protects water heaters, tankless units and fixtures from scale and makes soap work better. Ask your water utility for its current hardness figure, or have the water tested, before you buy.
Whole-house filtration
Whole-house carbon filters reduce chlorine taste and odor. Point-of-use filters at the kitchen sink can be certified to reduce lead and other contaminants. A plumber can install the right system and the bypass valves needed for maintenance.

Who can test a backflow preventer?
Only a tester certified under your state's and utility's rules. Ask for proof of certification and make sure the report is submitted to your utility.
What happens if I don't test my backflow device?
Utilities can issue notices and, eventually, suspend water service until the device is tested. Don't ignore the letter.
Does a softener affect drinking water?
Softened water contains a small amount of sodium. Many homeowners leave a separate unsoftened line at the kitchen sink for drinking and cooking.
Do you serve commercial properties for backflow?
Yes. See commercial plumbing.
