Why Southwest Florida Trusts Us
Certified. Local. Proven.
Since opening our doors, TK Plumbing has become Sarasota's go-to backflow specialists — licensed, insured, and trusted by homeowners, property managers, and commercial clients alike.
Your Tap Water Is Only Safe If This Device Is Working
Backflow happens when the normal direction of water reverses — pushing contaminated water from irrigation systems, pools, or industrial lines back into your clean drinking water supply. In Florida, it's not just a theoretical risk. Pressure drops from water main breaks, firefighting, or high-demand periods can trigger backflow at any time.
A backflow preventer is a mechanical valve that stops this from happening. But like all mechanical parts, it can fail — and a failed preventer offers zero protection.
Florida's subtropical humidity and salt-air exposure accelerate the internal corrosion of backflow preventer check valves. A device that "passed" two years ago may be silently compromised today. Annual testing — not just installation — is what keeps your water safe and your local code compliance intact.
Sarasota County and Manatee County both require annual backflow testing on irrigation systems connected to potable water. Failure to certify can result in fines or water service termination.

View All Service Areas →Residential backflow testing in Sarasota typically runs $75–$150 depending on the preventer type and property. Commercial testing starts around $125 and varies by system complexity. We provide an exact flat-rate quote before arrival — no surprises. If your device fails and needs repair, we'll quote that separately and get your approval first.
Yes. Sarasota County Utilities requires annual backflow preventer testing for any irrigation system connected to the potable water supply. Manatee County has the same requirement. Failure to provide a current test report can result in a notice of violation, service interruption, or fines. We file the certification directly with your utility so you never miss the deadline.
If your device fails, we diagnose the issue on the spot — most failures are a worn check valve or diaphragm, which we carry on our trucks. We'll quote the repair immediately and, with your approval, complete it the same visit. You'll leave the visit with a passing certification, not a second appointment waiting to happen.
A standard residential backflow test takes 45–90 minutes. Commercial systems with multiple devices take longer — typically 1.5–3 hours depending on the number of preventers. We'll give you an accurate time estimate when you book.
For most residential exterior systems, you don't need to be home — just ensure the technician has access to the preventer (typically near the irrigation meter). If the device is inside or in a locked space, someone will need to provide access. We'll confirm access requirements when booking.
We test and service all common types: Reduced Pressure Zone (RPZ) assemblies, Double Check Valve (DCV) assemblies, Pressure Vacuum Breakers (PVB), and Atmospheric Vacuum Breakers (AVB). If you're unsure which type you have, our technician will identify it on arrival.
Yes — and we offer bulk scheduling for property managers with multiple units or HOAs with shared irrigation systems. We'll schedule a full property sweep at once, file all reports, and provide a consolidated certification record. Contact us at 9413923846 or visit our commercial plumbing page for details.
Signs include: repeated failures on annual tests, visible corrosion or rust around the device, constant dripping from the relief valve, or a device over 10 years old. Florida's humidity accelerates wear faster than drier climates — a device that "looks fine" may have corroded internal check valves. Our test will tell you definitively.
