Backflow occurs when water flows in the wrong direction—from your plumbing system back into the public water supply or your home's clean lines. This reversal can carry chemicals, bacteria, or waste into the drinking water you use every day.
There are two primary causes:
Without a functioning backflow preventer, your home is vulnerable to contamination from lawn irrigation, water softeners, boilers, hose bibs, and more.
Backflow isn't limited to commercial buildings. It's a real concern in many Huntley residential systems, especially homes with secondary water sources, outdoor plumbing, or older irrigation setups.
If your plumbing system includes any of these features, a backflow preventer may be required by code—and critical to keeping your water safe.
A backflow prevention device is a mechanical valve or assembly designed to stop water from reversing direction. It allows water to flow into your system but blocks any backward movement.
We'll assess your system and recommend the appropriate device based on code requirements and water use.
Many local ordinances—including Huntley and surrounding towns—require annual backflow testing for specific devices to ensure continued performance. If your home has a lawn irrigation system, pool, or boiler, your device likely needs certified testing.
All tests are performed by our certified backflow testers, and we handle the paperwork so you don't have to worry about deadlines or fines.
If your system is missing a backflow device—or you're unsure whether your existing one is working—we can help. Hansen provides backflow preventer installation and replacement for homes throughout Huntley and nearby suburbs.
We'll select and install the proper device type, ensure it's code-compliant, and test it for performance before we leave.

Don't ignore these signs—an old or faulty device won't protect your home when it counts.
Local plumbing codes and water authorities enforce backflow prevention requirements to protect the public water supply. Failure to comply can lead to:
In Huntley and most surrounding towns, annual backflow testing is required for any installed device—especially on sprinkler systems, boilers, or pools.

We offer transparent pricing and bundled testing services for homes with multiple devices. And if your system fails inspection, we'll credit the test cost toward your repair.
