What is backflow, and why does it matter?
Your water is supposed to flow one way, from the supply into your home or business. Backflow is when that flow reverses, and water that has left your clean plumbing gets pulled or pushed back into the supply. When that happens, contaminants, chemicals, fertilizer, or other unsafe water can enter your drinking water.
A backflow prevention assembly is a device that stops this reverse flow, protecting your water and the public supply. It matters because the contamination it prevents can be a genuine health hazard, which is why testing is generally required by code.
What causes backflow?
Backflow happens because of two pressure conditions.
Either can pull non-potable water into your clean supply if there is a cross-connection and no protection.
Where backflow protection is needed
Certain connections carry a higher risk and typically require a backflow assembly:
Irrigation systems are one of the most common residential reasons a home needs a backflow device and annual testing.
Do I need backflow testing in Hickory?
In most areas, backflow prevention assemblies must be tested regularly, usually once a year, and after any installation or repair, to confirm they are working. Requirements are set by the water provider and local code, so the exact rules depend on your property and connection. Homes and businesses with irrigation systems, commercial connections, and certain other setups commonly need annual testing. We can confirm the requirements for your property through the City of Hickory water utility at hickorync.gov and handle the testing and paperwork for you.

Types of backflow prevention assemblies
Different connections call for different devices, and the right one depends on the level of hazard:
- Reduced pressure zone assemblies, for higher-hazard connections
- Double check valve assemblies, for lower-hazard connections
- Pressure vacuum breakers, common on irrigation systems
- Atmospheric vacuum breakers, for certain applications
- Hose bib vacuum breakers, a simple protection for outdoor faucets
We assess your connection and install or test the correct device for your situation and code.
Why is my backflow test required every year?
Backflow assemblies have internal parts, springs, seals, and checks, that wear over time. A device that passed last year can fail this year without any outward sign. Annual testing catches a failing assembly before it stops protecting your water, which is why water providers require it. It is a small yearly step that keeps your drinking water safe and keeps you compliant.
