What Is Backflow, and Why Is It a Problem?
Under normal conditions, water flows from the municipal water supply into your property. However, if water pressure suddenly drops because of a water main break, heavy water usage, or firefighting activity, water can reverse direction. This is known as backflow.
When that happens, non-potable water (from lawn irrigation, chemical dispensers, or boiler systems) can be pulled back into the clean water supply. This can introduce fertilizers, pesticides, bacteria, and industrial chemicals into the drinking water serving your property and potentially your neighbors.
A certified backflow prevention device allows water to flow in only one direction, helping protect both your property and the public water system.

Florida requires routine testing to confirm your backflow preventer is functioning correctly. Our certified testers perform field testing on all major assembly types, submit the required documentation to the appropriate utility authority (City of Sarasota, Sarasota County, Pinellas County, or Hillsborough County), and provide copies for your records. If your device does not pass inspection, our team can also recommend the appropriate repair or replacement options.
Learn moreTypes of Backflow Prevention Devices
The right device for your property depends on the level of hazard present and your connection type. Common options for backflow prevention in Sarasota, FL, include:
- Reduced Pressure Zone (RPZ) Assemblies: The highest level of protection. Required by the City of Sarasota for all non-residential properties. Uses two check valves plus a relief valve that opens if either check fails, actively releasing water rather than allowing backflow.
- Double Check Valve Assemblies: Two independent check valves in series. Suitable for low-to-moderate hazard applications such as fire sprinkler lines and some irrigation systems.
- Pressure Vacuum Breakers (PVBs): Mechanical devices installed on irrigation systems to prevent siphonage. Must be installed above the highest irrigation head.
- Residential Dual Check Valves: Non-testable devices installed at the meter for homes with auxiliary water sources (wells, ponds, or reclaimed water).
Every property has different backflow prevention requirements. Our licensed plumbers evaluate your plumbing system, identify the appropriate assembly based on your property’s hazard level and local regulations, and complete the installation to meet all applicable codes.
Does My Property Require a Backflow Preventer?
All Non-Residential Properties
The City of Sarasota requires every commercial water customer to maintain a backflow preventer at both domestic and fire service connections. This applies to:
- ✓ Office buildings and commercial retail spaces
- ✓ Restaurants, hotels, and hospitality properties
- ✓ Medical and dental facilities
- ✓ Industrial and manufacturing sites
- ✓ Schools, universities, and government buildings
- ✓ HOA common areas and multi-family properties
- ✓ Plants, refineries, and warehouses
Sarasota County notifies commercial customers 30 days before their annual test is due. Failure to test can result in a notice of violation and, ultimately, disconnection of water service.
Residential Properties with Cross-Connections
Not every home requires a backflow preventer. However, many residential properties need one if they have:
- ✓ A lawn irrigation system connected to your home's potable water supply
- ✓ A private well, lake, pond, or reclaimed water source
- ✓ A fire suppression line
- ✓ A pool fill valve with a submerged inlet
If you're unsure whether your property requires a backflow prevention device, our team can evaluate your plumbing system and explain any local requirements.
High-Risk Commercial Applications
Some commercial properties require higher levels of backflow protection because of the activities performed on-site. These commonly include car washes, restaurants, hotels, medical facilities, food processing facilities, and commercial properties where chemicals are mixed or dispensed through the plumbing system.
