If you’ve ever heard the term "backflow" and wondered what it means, you’re not alone.
Backflow occurs when water flows the wrong way through your plumbing system—potentially pulling contaminants into your clean water supply. It’s a serious but often overlooked issue that can affect both residential and commercial properties. Whether you’re a homeowner or property manager, understanding backflow—and making sure your system is protected—can help keep your water safe and your property compliant.
What Is Backflow?
Backflow happens when the normal direction of water flow reverses due to changes in pressure. This reversal can allow dirty or contaminated water (from sources like irrigation lines, pools, or nearby drainage) to enter your home’s potable water supply.
Think of it like this: if the water pressure in your main supply line drops unexpectedly—say, due to a burst pipe or hydrant use nearby—it can create suction that pulls contaminated water back into your clean water system.
Why Backflow Matters
The biggest concern with backflow is contamination. If fertilizers, pesticides, bacteria, or chemicals enter your drinking water, it could pose serious health risks to your family or tenants.
Backflow isn’t just a nuisance—it’s a public health issue. That’s why state and local codes often require backflow prevention devices and regular testing for irrigation systems, commercial buildings, and some residential properties.
What Causes Backflow?
Backflow typically occurs due to two main issues:
-
Backpressure: When the pressure in your plumbing system becomes higher than the water supply line (usually caused by pumps or elevated tanks).
-
Backsiphonage: When water pressure in the main supply line drops, creating suction that pulls water backward.
Common causes include:
- Broken water mains
- Fire hydrant use
- Poorly maintained irrigation systems
- Garden hoses left submerged in pools or buckets
- Unprotected outdoor faucets
How Backflow Testing Works
Backflow preventers are mechanical devices that keep contaminated water from flowing backward into your clean supply. Over time, these devices can wear down or fail—which is why regular testing is so important.
Our certified technician will:
- Visually inspect the device for damage
- Connect test gauges to check pressure levels and valve function
- Identify any leaks or failures
- Provide a full report and recommendations
Testing typically takes less than an hour and ensures you’re meeting local compliance standards.
When Should You Get Your Backflow Tested or Repaired?
In many Texas municipalities—including the greater Houston area—annual backflow testing is required for:
- Homes with irrigation systems
- Commercial properties
- Properties with fire sprinkler systems or pool connections
Even if it’s not mandated, we recommend testing:
- After a system installation or repair
- Following a major storm or freeze
- Annually as part of your home maintenance plan
If your device fails, we also provide backflow repairs, replacements, and certified documentation for code compliance.
