What Is Backflow and Why Does It Matter for Tampa Bay Homeowners?
Backflow occurs when water flows in the wrong direction through your plumbing — potentially allowing contaminated water from your irrigation system, pool, or outdoor lines to mix with your clean drinking water supply. In Tampa Bay, backflow prevention is not optional: Hillsborough County and Tampa Bay Water require annual backflow preventer testing for all properties with an irrigation system connected to the public water supply.
Fix It Today Plumbing (License CFC055692) is a licensed backflow testing and prevention contractor serving Tampa, Brandon, Riverview, Wesley Chapel, and Greater Tampa Bay.
Why Is Annual Backflow Testing Required in Tampa Bay?
The Florida Department of Environmental Protection (FDEP) and local water utilities mandate annual testing because:
- Cross-connection hazards — Irrigation lines run near fertilizers, pesticides, and soil contaminants
- Pressure fluctuations — Sudden drops in municipal pressure (from main breaks, fire hydrant use, etc.) can cause backflow
- Public health protection — Contaminated water entering the drinking supply is a serious health risk
- Code compliance — Failure to test can result in utility notices and water service interruption
Tampa Bay Water and Tampa Bay regional utilities enforce this requirement. Your annual test results must be submitted to the utility — Fix It Today Plumbing handles this paperwork on your behalf.
What Happens During a Backflow Preventer Test?
A licensed backflow tester visits your property and:
- Locates the backflow preventer — Usually near your irrigation shutoff or water meter
- Attaches differential pressure test gauges — Measures the check valves' ability to hold pressure
- Records pass/fail readings — Documents differential pressure across each check valve
- Submits the test report — Files results with your water utility
- Repairs or replaces failing devices — If a check valve fails, we repair it on the spot when possible
The entire test takes 30–45 minutes for a standard residential backflow preventer.
What Types of Backflow Preventers Are Used in Tampa Bay Homes?
- Double Check Valve Assembly (DCVA) — Most common for residential irrigation in Hillsborough and Pasco County
- Reduced Pressure Zone (RPZ) Assembly — Required for higher-hazard applications (pools, chemical injection systems)
- Pressure Vacuum Breaker (PVB) — Common on older irrigation systems; must be installed above the highest sprinkler head

How Do I Know If My Property Requires Backflow Testing in Tampa Bay?
Your property almost certainly requires annual testing if it has:
- A lawn irrigation system connected to the public water supply
- An in-ground pool or spa with an auto-fill connection
- A fire suppression system
- Any outdoor hose bib with a chemical injector
If you've received a notice from Tampa Bay Water, Hillsborough County, or your HOA about backflow testing, the deadline is real — non-compliance can trigger a service interruption.
