If you have an irrigation system, a commercial building, or certain types of residential connections, you probably have a backflow prevention assembly. Most Florida utilities require that assembly to be tested every year by a certified tester.
Why backflow matters
Backflow assemblies keep contaminated water from flowing backwards into the public drinking supply. Without them, a pressure drop in the main could pull fertilizer, sewage, or chemicals into your neighbor's tap. That's why the test is legally required.
How the test works
A certified tester shows up with a calibrated test kit, shuts off downstream water, and verifies that the check valves and relief valve in your assembly close properly. The test takes 15 to 30 minutes per assembly. We file the paperwork directly with your utility.
What if it fails?
Most failures are fixable with a rebuild kit (springs and seals). We usually carry kits on the truck for the common models: Watts 909, Wilkins 975XL, Febco 860, and Zurn 375. If the whole assembly is corroded or out of spec, we replace it.
What if you miss your due date?
Utilities will issue warnings, then fines, then eventually shut off your water. Don't let it get there. We send reminders to our backflow customers automatically.
