Why is backflow preventer testing important? Because it helps keep your potable water supply safe from impurities. What you don’t want is contaminated water seeping back into the water you drink. A properly working backflow preventer keeps this from happening.

If you have a testable backflow preventer at your home, it’s a requirement that it be tested annually. It may be a pressure vacuum breaker (PVB) for your irrigation system or a reduced pressure zone (RPZ) backflow preventer serving some other purpose. You may have received a letter from the county reminding you to have backflow preventer testing completed. Alpha Plumbing has plumbers who are trained and certified in backflow prevention and can test your device to make sure it’s functioning properly and make the appropriate reports with Anne Arundel County, Howard County, Baltimore County, Baltimore City, or WSSC to keep it in compliance.

Some homes have non-testable backflow devices – a double check valve is a common one. These devices typically are installed on the main water service coming into your home or to keep a fire sprinkler line from backflowing. Code requires that these non-testable backflow preventers be replaced every 5 years.
