DIY Dangers: Why Some Plumbing Tasks Are Best Left to the Pros
Published by Lake County Backflow
Lake County, IL | Backflow Prevention & Testing Services
Trying to fix plumbing issues on your own can be tempting—especially with all the DIY videos floating around online. But when it comes to your backflow prevention system and other sensitive plumbing components, the risks often outweigh the rewards.
At Lake County Backflow, we’ve seen firsthand how DIY attempts can cause more harm than good. Here’s what every Illinois homeowner should know before grabbing that wrench.
1. Backflow Prevention Devices Aren’t Your Average Fixture
Backflow preventers are highly regulated and precision-engineered devices. They’re installed to protect your drinking water from contamination caused by pressure changes in the water system. If installed or maintained incorrectly, they can fail silently—putting your family or tenants at risk.
➡️ Bottom Line: Only state-certified backflow testers can legally inspect and test these systems in Illinois.
📎 Explore our certified testing services
2. The Risks of DIY Repairs
Attempting to fix or “adjust” a backflow preventer yourself can result in:
Voiding your warranty
Failing municipal inspections
Leaking or burst components
Cross-contamination of clean and dirty water
Fines or code violations
Even simple tasks like shutting off a valve incorrectly can damage seals or internal parts that require precise pressure regulation.
➡️ Not sure if your device needs service? Request a professional inspection here.
3. Winterizing Your System? Don’t Go Solo
Each year, Illinois homeowners face freeze damage from improper winterization. Outdoor backflow preventers, especially those on irrigation lines, must be properly drained and insulated before winter. One mistake can crack the device—and cost you hundreds in spring repairs.
We recommend letting a licensed technician handle:
Shut-off and blowout procedures
Inspecting for leaks or damage
Insulating above-ground systems
Testing post-winter for full functionality
4. Google Can’t Diagnose Everything
We love resourceful customers—but Google and YouTube can’t replace years of plumbing and testing experience. Backflow prevention systems often require specialized tools and calibrated test equipment that aren’t available at your local hardware store.
➡️ Hiring a pro ensures accuracy, code compliance, and long-term peace of mind.

When to Call a Pro

Visible leaking near your backflow preventer
Water discoloration or bad taste
Low pressure in your sprinkler or fire suppression system
A notice from your water district about overdue testing

We’re here to keep your system safe, compliant, and functioning year-round.

Final Word:
DIY is great for patching drywall or assembling furniture—but when it comes to your plumbing and backflow system, professional testing and service is the safest route. Trust Lake County Backflow to help you protect your water and stay compliant with local regulations.
How to Prep for Your Annual Backflow Test in Illinois
If you're a homeowner or business owner in Illinois, staying compliant with backflow testing requirements is key to protecting your property and your local water supply. Annual backflow prevention device testing helps ensure contaminated water doesn't reverse flow into clean water lines—a serious health hazard if left unchecked.
In this post, we’ll walk you through how to prepare for your backflow test so it goes smoothly, meets your city or village’s regulations, and avoids costly delays or rescheduling.
What Is a Backflow Test?
A backflow test is an inspection performed by a licensed and certified backflow tester to verify that your backflow prevention device is functioning correctly. These devices are typically found on:
Irrigation systems
Fire sprinkler systems
Commercial and industrial plumbing systems
In many areas—including Lake County, Illinois—annual testing is required by local municipalities or water providers.
1. Locate Your Backflow Preventer
Start by identifying where your backflow device is installed. It’s commonly located:
Outdoors near your irrigation system or water meter
Inside a utility or mechanical room (in commercial properties)
In or near fire protection systems
Knowing the exact location helps both you and your backflow tester get started faster.
2. Clear Access to the Device
To perform a proper backflow test, your technician needs clear access to the device. Make sure to:
Trim bushes or landscaping if it’s outside
Remove snow or debris
Unlock any gates, rooms, or enclosures around the device
This ensures the testing equipment can be connected without obstacles.
3. Confirm the Water Supply Is On
Backflow testing requires water pressure to measure performance. If the system is turned off (often the case in winter), turn it back on before your scheduled test.
If you’re not sure whether your system is active, your landscaper or maintenance crew can assist.
4. Notify Tenants or Staff (If Applicable)
If your backflow device is in a shared space or could cause a brief water interruption, let others know in advance. This applies to:
Apartment buildings
Office complexes
Commercial tenants
Proactive communication helps avoid complaints or confusion during the service window.
5. Look for Visible Damage or Leaks
Take a quick visual inspection around the device. If you notice:
Leaking water
Rust or corrosion
Cracks (common after freezing temperatures)
…it’s best to report this before testing. Damage can prevent the test from being completed and may require repairs first.
6. Hire a Certified Backflow Tester in Illinois
In Illinois, backflow testing must be done by a state-certified backflow prevention tester. At Lake County Backflow, we’re fully licensed, insured, and specialize in testing for:
Irrigation backflow systems
Fire protection systems
Commercial and industrial plumbing
We handle test submission, documentation, and reminders for future tests to keep you in full compliance.

Keeps your property compliant with local ordinances
Avoids fines or service interruptions
Identifies problems early, before they become expensive

Your annual backflow test doesn’t need to be stressful. A little preparation goes a long way in keeping your water safe and your plumbing systems running smoothly.

What Is Backflow Testing and Why It's Essential
Backflow testing might not be the first thing that comes to mind when you think about plumbing or property maintenance, but it plays a critical role in protecting public health. Whether you're a homeowner, business owner, or property manager, understanding backflow and why testing is necessary can help prevent serious contamination issues in your water supply.
What Is Backflow?
Backflow happens when water flows in the reverse direction from its intended path. Normally, water should flow from the municipal supply into your home or building. But under certain conditions—like a drop in pressure or a malfunction in the system—contaminated water can be sucked or pushed back into the clean water supply. This is called back siphonage or back pressure.
The risk? Contaminants like fertilizers, pesticides, human waste, or industrial chemicals can enter your drinking water. And that’s not just a plumbing problem—it’s a public health hazard.
How Does a Backflow Preventer Work?
To stop this from happening, plumbing systems use a backflow preventer—a device that only allows water to flow in one direction. Think of it like a one-way valve for your water line. It’s especially important in systems where there’s a cross-connection between clean and potentially contaminated water sources. These include irrigation systems, fire sprinklers, and commercial plumbing setups.
But here’s the catch: backflow preventers can wear out, break, or malfunction. That’s where testing comes in.
What Is Backflow Testing?
Backflow testing is the process of checking that your backflow prevention device is working properly. It typically involves:
Shutting off the water supply to isolate the device.
Using a test kit to measure pressure and flow through the device.
Checking valves to make sure they open and close correctly.
Looking for leaks or signs of failure.
The test must be done by a certified backflow tester—someone trained and licensed to handle this specific task.
Why Is Backflow Testing Necessary?
1. Health and Safety
This is the number one reason. If your backflow preventer fails and you don’t catch it, contaminated water can end up in your drinking supply. That means bacteria, chemicals, or even raw sewage can get into your faucet. Backflow incidents have led to serious illnesses and even deaths in the past.
2. Legal Requirements
In many cities and states, annual backflow testing is mandatory for certain properties. This is especially true for commercial buildings, apartment complexes, or any property with irrigation systems or fire suppression systems. Failing to comply can lead to fines, shutoff notices, or worse.
3. Early Detection of Issues
Backflow testing doesn’t just protect water quality. It also helps identify leaks or mechanical failures in your plumbing system that could become costly problems down the road.
4. Maintaining Insurance and Compliance
Some insurance policies require regular backflow testing to maintain coverage. Plus, keeping up with your local utility or city’s regulations avoids any disruptions in service.
Who Needs Backflow Testing?
Not every home has a backflow preventer that needs annual testing, but the following types of properties usually do:
Commercial buildings
Multifamily residential properties
Properties with irrigation systems
Facilities with fire sprinklers
Industrial or medical facilities
If you’re unsure, your local water authority or a licensed plumber can tell you whether your property needs it.
Final Thoughts
Backflow testing isn’t just a box to check—it’s a crucial safeguard for your water and your community. Skipping it puts everyone at risk. If your property has a backflow preventer, make sure it gets tested annually by a certified professional. It’s a small step that makes a big difference in keeping water safe, clean, and flowing in the right direction.
