Backflow Prevention & Testing in Englewood, FL

Best in Englewood Since 2012. One Call for Testing, Repair & Installation.

Backflow occurs when water reverses direction through your plumbing, pulling contaminants from irrigation lines, well pumps, reclaimed water systems, or other non-potable sources back into your clean water supply. A backflow prevention device stops that reversal at the point where the municipal supply enters your property. Florida state law requires these devices to be tested periodically by a certified tester, and both the Englewood Water District and Charlotte County utilities enforce compliance schedules for residential and commercial properties.

Mike Douglass Plumbing has provided backflow prevention testing, repair, and installation throughout Englewood and Charlotte, Sarasota, and Manatee Counties since 2003. We’re a full-service licensed plumber, which means we can test your device, diagnose any failure, and repair or replace it in a single visit without sending you to a separate contractor. Named Best in Englewood every year since 2012, our team is licensed, insured, and backs every job with a warranty.

How a Backflow Preventer Works

A backflow preventer uses spring-loaded check valves that allow water to flow from the municipal main into your property but close automatically when a backflow condition occurs, stopping reverse flow before contaminants can reach your potable water. These devices are typically installed directly after the water meter, roughly 12 to 18 inches above finished grade. A licensed plumber assesses your property’s cross-connection risk and selects the appropriate device type for the application.

Standard device types used on Englewood properties include:

• Reduced pressure (RP) assemblies for high-hazard applications, including most irrigation and commercial connections
• Double check valve (DCV) assemblies for lower-hazard commercial and multi-unit residential connections
• Pressure vacuum breakers (PVB) commonly used on residential irrigation systems
• Spill-resistant vacuum breakers (SVB) for indoor or lower-risk cross-connection points

The correct device depends on your property’s hazard classification and configuration. We assess that during our initial visit and can explain the options before any work begins.

Who Needs a Backflow Preventer in Englewood?

Englewood Water District requires a reduced-pressure backflow preventer at all non-residential properties. On the residential side, an RP backflow preventer is required if your property has an irrigation system, a well pump or auxiliary water source, a building three or more stories tall with a pressure booster pump, a water meter one inch or larger in diameter, available reclaimed water service, four or more residential units on a single meter, or a fire sprinkler system.

Once installed, the testing schedule depends on your property type. Non-residential backflow preventers must be tested once per year under Englewood Water District rules; residential preventers must be tested once every two years. Tests must be performed by a certified backflow tester on the Englewood Water District approved list, and the completed report is submitted directly to EWD to keep your compliance records current. Properties in Charlotte County served through North Port Utilities follow that utility’s cross-connection control program and report-filing requirements. We serve customers throughout both service areas and can handle test report filing as part of the process.
