What Is a Backflow System?
Backflow occurs when water flows in the opposite direction from its intended path, potentially contaminating your clean water supply with harmful substances like fertilizers, pesticides, chemicals, or sewage. A backflow prevention device stops this from happening—protecting both your property and the public water system.
Why Do I Need a Backflow Device?
You need a backflow device if your plumbing system connects to:
- An irrigation system
- A fire sprinkler system
- Commercial boilers
- Swimming pools
- Any high-risk connection to the municipal water supply
Installing a backflow prevention system is not just smart—it’s often required by Texas law, especially for commercial properties and some residential systems.
How Often Should I Have My Backflow System Tested?
Just like a car needs regular tune-ups, backflow systems require annual testing to ensure they’re running at peak performance and efficiency. All cities and municipalities in Texas require scheduling a backflow test every year.
Types of Backflow Devices We Service & Install:
Double Check Valve Assembly (DCVA): Commonly used for irrigation systems and low-risk commercial applications.
Reduced Pressure Zone Assembly (RPZ): Used in high-hazard applications where contamination risk is significant.
Pressure Vacuum Breaker (PVB): Ideal for lawn irrigation systems
Not sure which type is right for your property? Our licensed plumbers can inspect your system and recommend the best solution.
What’s the Lifespan of a Typical Backflow System?
The lifespan of a typical backflow device can vary depending on several factors, including the type of backflow device, its usage, and how well it’s maintained. However, with proper care and regular maintenance, most modern backflow devices can last between 10 and 15 years.
Whether you need a new backflow prevention device installed, annual testing, or repairs, Smith and Son Plumbing has you covered. As a local, family-owned plumbing company, we deliver dependable service with clear pricing and no surprises.

Signs My Backflow Device Needs to Be Replaced
While regular maintenance can extend the life of a backflow device, there are certain signs that indicate it may be time to consider a replacement. If the backflow device is over 10-15 years old, it’s likely not as efficient as newer models and may be prone to more frequent breakdowns.
1. Visible Leaks or Drips
Water leaking from the valve body, fittings, or relief valve is a clear sign something’s wrong. Persistent leaks often mean internal seals or components have failed.
2. Unusual Water Pressure Changes
If you notice sudden drops in water pressure or inconsistent water flow, it may be due to a malfunctioning backflow device restricting water flow.
3. Water Discoloration or Foul Odors
Discolored water or strange smells coming from your faucets could be a sign that contaminated water is entering your clean supply—often due to backflow device failure.
4. Failed Annual Test
If your device fails its state-required annual backflow test, it must be repaired or replaced immediately to remain compliant with Texas regulations.
5. Corrosion or Physical Damage
Visible rust, cracks, or broken components can affect performance and are a strong indicator that the device is near the end of its useful life.
While some of these issues may be repairable, it’s important to consult with a professional plumber to assess the overall condition of the backflow device and determine if a replacement is the most sensible course of action.
