Backflow Testing in Charlotte, NC
We make backflow compliance easy
If you received a letter from Charlotte Water saying your backflow assembly is due for testing, this is the page you need. Alpha Drain is on Charlotte Water's approved tester list and tests backflow prevention assemblies for homes, businesses, irrigation systems and fire lines. A certified tester checks the assembly with a calibrated gauge, and we send the results to the utility so the notice goes away.
The price is $199 per assembly. If the assembly fails, we show you the readings, explain what is wrong and can handle the backflow repair and retest. Property managers with many assemblies get one schedule and one point of contact.

How a backflow test works
- Send us your notice or tell us the type and location of the assembly. We schedule the test, usually within days.
- The tester briefly shuts off water downstream of the assembly. For a business we can schedule around your hours.
- A calibrated test kit is connected to the assembly's test ports and each check valve and relief valve is measured against the required values.
- Water is turned back on and you get the results on the spot.
- We file the passing report with your water provider. If the assembly fails, we explain the repair and retest after it is fixed.

Backflow Testing Questions, Answered
A backflow preventer is a valve assembly that lets water flow into your property and stops it from flowing back into the public supply. A cross connection is any point where non-drinking water could be pulled backward, for example from an irrigation line, a boiler or a chemical feeder, when pressure drops. The internal checks and springs wear out, so testable assemblies are checked with a gauge every year.
Yes. The federal Safe Drinking Water Act makes water suppliers responsible for protecting the public supply, and states and local utilities enforce that through cross-connection control programs. Charlotte Water requires assemblies to be tested when installed and on a recurring schedule by a company on its approved tester list. Commercial assemblies are tested every year. For a residential irrigation system, go by the due date on your notice.
Alpha Drain charges $199 per assembly for a certified test, and that includes filing the report with your water provider.
Most tests take 20 to 30 minutes per assembly. Water downstream of the assembly is off for part of that time. For businesses we can schedule the test before opening or during a slow period.
We show you the readings and explain which part failed. Often it is a worn check or a fouled relief valve that can be repaired with a rebuild kit. Once it is fixed we retest and file the passing report. See backflow repair for details.
