Direct answer
When do you need a new backflow preventer installed?
You need one whenever a new cross-connection is created — a new irrigation system or pool, a fire line, new construction or a remodel, or when your utility now requires a device on your service. Flamingo Plumbing & Backflow selects the correct assembly type, sizes it, pulls the permits, and installs it to code across Palm Beach, Broward, Martin, St. Lucie, and Miami-Dade counties — backflow expertise since 1992, licensed (CFC1426338), with the first certification test included.
What we handle
What backflow installations does Flamingo handle?
New backflow preventers for homes and commercial properties — domestic, irrigation, fire-line, and commercial assemblies. We choose the correct type for the application, size it, pull permits, install to code, and run the first certification test. Upfront pricing, every job guaranteed for at least a year.
Irrigation & pool installs
A new sprinkler system or pool is a cross-connection. We add the right irrigation assembly, sized to your line, to keep that water out of the clean supply.
Fire-line & commercial installs
Fire-suppression lines and commercial services need the correct high-hazard assembly. Our certified techs spec, size, and install it to local code.
When do you need one installed?
When does a property need a new backflow preventer?
A backflow preventer stops used or contaminated water from reversing into the clean supply — guarding against backpressure and backsiphonage. Any of these typically triggers a new install, and most fall under local code.
- You added a new irrigation system or pool.
- You have a fire line or fire-suppression system.
- You are building new or doing a remodel or addition.
- Your utility now requires a device on your cross-connection.

Backflow install questions
Backflow installation questions people actually ask.
Do I need a backflow preventer installed?
You do anytime a new cross-connection is created — a new irrigation system or pool, a fire-line system, new construction or a remodel, or when your utility now requires a device on your service. A backflow preventer keeps used or contaminated water from reversing into the clean supply, and most local codes make it mandatory in these cases.
What type and size of backflow preventer do I need?
It depends on the application and the degree of hazard — domestic, irrigation, fire-line, and commercial each call for a different assembly type, and the size has to match your service line and flow. A certified Flamingo tech assesses the cross-connection and selects and sizes the correct assembly so it passes inspection and actually protects the supply.
Does a new backflow install need a permit?
In most cases, yes. New backflow installations are governed by local plumbing code and utility cross-connection rules, and the device has to be installed and certified by a licensed professional. Flamingo handles the permitting and installs to code (CFC1426338, FPC17-000046).
Can I install a backflow preventer myself?
It needs to be installed by a certified professional to meet local code and to actually protect the water supply. The wrong type, size, or orientation can fail inspection and leave the supply unprotected. Flamingo has installed backflow assemblies across South Florida since 1992.
How much does a backflow installation cost?
It depends on the assembly type and size, the application, permitting, and the plumbing at the connection point. Pricing is upfront before any work starts and financing is available — call (561) 448-3200 for a quote on your project.
Do you certify the backflow device after you install it?
Yes. Every new assembly gets its first certification test once it’s installed, and we file the paperwork with the utility. After that it needs a recurring yearly test — see our backflow testing & certification page for the annual requirement.
