Protecting your property’s clean water supply is more than a safety measure; in Manatee and Sarasota Counties, it is a legal requirement. At Griggs Plumbing, we provide professional certified backflow testing and repair services for homeowners, HOAs, and commercial businesses.
As a family-owned company serving the Suncoast for over a century, we handle the technical testing and the municipal paperwork, ensuring your property stays compliant and your water stays pure.
What is Backflow Testing?
In its simplest terms, backflow testing is a specialized plumbing inspection that ensures your drinking water only flows in one direction.
“Backflow” occurs when a sudden change in water pressure (caused by a broken water main or a nearby fire hydrant being used) reverses the direction of water flow. Without a properly functioning backflow prevention device, contaminated water from irrigation systems, pools, or industrial equipment could be sucked back into your clean, potable water lines.
Annual testing verifies that the internal valves and seals of your device are strong enough to prevent this “cross-contamination,” keeping your family or your customers safe.

If a device is severely damaged, broken due to cold, or doesn’t meet current Florida rules, we will install a new, approved device for you.
Backflow Testing Process
Most cities in Sarasota and Manatee Counties require backflow prevention devices to be tested once a year by a certified technician. These inspections make sure your system works properly and keeps the water supply safe.
What to Expect During Your Backflow Test
- Visual Inspection: The plumber checks for leaks, corrosion, or damage around your backflow assembly.
- Pressure Differential Testing: Specialized gauges measure water pressure at each valve to ensure correct direction and performance.
- Calibration or Cleaning: If needed, the technician cleans and adjusts the device for optimal operation.
If your system doesn’t pass the test, our team explains the problem clearly and provides fast, cost-effective solutions, from small repairs to full device replacement.
