DIY Dangers: Why Some Plumbing Tasks Are Best Left to the Pros

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.

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.
