Backflow Testing & Prevention in Carrollton, TX
If your irrigation system or business needs its backflow prevention assembly tested this year, or you need one installed, we handle both the testing and the paperwork.
Call (469) 856-7724Backflow happens when water pressure reverses direction in a pipe, which can pull water from an irrigation system, a pool, or a commercial process line back into the clean drinking water supply. A backflow prevention assembly is a mechanical device installed at the connection point that stops that reversal, and testing confirms the device is actually working the way it's supposed to.
Who Needs Annual Backflow Testing
Across Texas, water utilities generally require annual testing for irrigation systems and other higher-risk connections, businesses like restaurants, medical facilities, and anywhere a process could introduce contaminants into the water system. Carrollton's water utility follows that same general framework common statewide. The exact requirement for a given property depends on the type of connection, so it's worth confirming your specific testing schedule with your water provider or with us directly.
Who's Qualified to Test a Backflow Device
Testing isn't something just any plumber can sign off on. In Texas, it has to be performed by someone holding a specific credential, a TCEQ-licensed customer service inspector, a TSBPE-licensed plumbing inspector, a TSBPE plumber with the Water Supply Protection Specialist endorsement, or a licensed backflow prevention assembly tester for irrigation-specific testing. Ask to see the tester's credential before scheduling, since an invalid test won't satisfy your water provider's requirement.
Installation for New Connections
A new irrigation system, a pool fill line, or a commercial process connection tied into the potable water supply typically needs a backflow prevention assembly installed as part of the setup. We size and install the right device type for the connection and get it tested and certified before it goes into service.
Device Types We Work With
Backflow prevention assemblies come in a few common configurations, reduced pressure zone assemblies, double check valve assemblies, and pressure vacuum breakers among them, each suited to different levels of risk depending on the connection. An irrigation system generally uses a different assembly type than a commercial process line with a higher contamination risk, and picking the right one for the specific connection is part of doing the installation correctly the first time.
Keeping Your Testing on Schedule
Missing an annual test isn't just a compliance issue, it also means a device could be quietly failing without anyone noticing until it matters. We can help set a reminder schedule so your property's testing stays current year over year rather than becoming a scramble whenever your water provider sends a notice.

What Happens During a Test
A backflow test measures whether the assembly's internal check valves are holding pressure the way they're designed to. It's a quick, non-invasive process for the property owner, typically done without shutting off water to the rest of the building, and results in either a pass or a documented failure that specifies what needs repair. We submit the completed test report to your water provider as part of the visit, so you're not left chasing down paperwork afterward.
Frequently Asked Questions
Backflow is when water flows in reverse through a pipe, potentially pulling contaminated water backward into the clean drinking water supply. A backflow prevention assembly is a mechanical device that stops that reverse flow from happening.
Many Texas water utilities require annual testing for irrigation systems and other higher-risk connections, and Carrollton's utility follows that same general pattern common across the state. Your specific requirement depends on the type of connection and how your water provider has structured its cross-connection control program.
Testing has to be done by someone holding the right credential. In Texas that generally means a TCEQ-licensed customer service inspector, a TSBPE-licensed plumbing inspector, a TSBPE plumber with the Water Supply Protection Specialist endorsement, or a licensed backflow prevention assembly tester for irrigation systems specifically.
A failed test means the device needs repair or replacement before it will pass, since a failed backflow preventer isn't doing its job of protecting the water supply. We handle both the repair and the retest.
Yes, an irrigation system connected to the potable water supply needs a backflow prevention assembly installed as part of the setup, both as a safety matter and typically as a code requirement.
The device type and how many need testing at the property both affect the number, so that's worked out when scheduling rather than guessed on the call.
Yes, a property with several devices, say an irrigation connection and a separate process line, can usually have all of them tested and documented in the same visit.
