The Dangers of DIY Plumbing and When to Call a Professional

March 3, 2025

BY MITCH WRIGHT PLUMBING, HEATING & AIR

Plumbing issues can sneak up on anyone—a dripping faucet, a clogged drain, or a mysteriously low water pressure situation. When these problems arise, it’s tempting to roll up your sleeves, grab a wrench, and tackle it yourself. 

After all, there are countless YouTube tutorials and hardware store aisles promising quick fixes. But here’s the catch: DIY plumbing can sometimes turn a small issue into a costly disaster. At Mitch Wright Plumbing, we’ve seen it all, and we’re here to break down why going it alone isn’t always the best idea—and when it’s time to call in the pros.

Common DIY Plumbing Mistakes Homeowners Make (and How They Cost You More)

DIY plumbing sounds empowering until it goes wrong. Here are some of the most common missteps we see homeowners make—and how they end up costing more than calling a pro:

  • Overtightening fittings: It’s tempting to crank that wrench until the leak stops, but too much force can crack pipes or strip threads, leading to bigger leaks later.
  • Misusing chemical drain cleaners: These might blast through a clog, but they can also corrode your pipes over time, setting you up for an expensive replacement.
  • Ignoring building codes: Skipping permits or using the wrong materials might save money now, but it could fail a home inspection—or worse, cause damage insurance won’t cover.

These slip-ups don’t just hit your wallet; they waste your time and sanity, too.

The Importance of Hiring a Licensed Plumber for Complex Repairs

For simple tasks, a little DIY spirit can go a long way (more on that later). But when it comes to complex repairs—like repairing a burst pipe, replacing a water heater, or rerouting plumbing—there’s no substitute for a licensed professional. Why? Licensed plumbers bring training, experience, and the right tools to the table. They know how to diagnose the root cause of a problem, not just the symptoms, ensuring the fix lasts.

Plus, professionals carry insurance and warranties. If something goes wrong during a DIY job, you’re on the hook for the damages. With a licensed plumber, you’ve got peace of mind knowing the work is backed by expertise and accountability. At Mitch Wright Plumbing, our team stays up-to-date on industry standards and local regulations, so you don’t have to worry about a thing.

What You Can Safely Do Yourself and What Should Be Left to the Pros

So, where’s the line between DIY and pro territory? Here’s a quick guide:

  • Safe DIY tasks:
    • Unclogging a sink with a plunger
    • Tightening a loose faucet handle
    • Replacing a showerhead These are low-risk jobs that don’t need specialized tools or deep plumbing know-how.
  • Leave these to the pros:
    • Anything involving gas lines (like water heater repairs)
    • Major pipe replacements
    • Sewer line issues These can lead to dangerous leaks, water contamination, or health hazards if mishandled.

Real-Life Scenarios Where DIY Went Wrong: Lessons from Our Technicians

Our technicians have some stories that’ll make you think twice before grabbing that pipe wrench. Take one homeowner who tried to fix a leaky toilet by replacing the wax ring themselves. Sounds simple, but they didn’t seat it properly, and water seeped into the subfloor for weeks unnoticed. By the time we got the call, they were facing mold damage and a hefty repair bill—far more than the cost of hiring us from the start.

Then there was the guy who attempted a water heater swap without shutting off the main water supply. Cue a flooded basement and a very soggy afternoon. These aren’t just cautionary tales—they’re reminders that plumbing’s trickier than it looks. Our team’s seen the aftermath, and we’d rather help you avoid it altogether.
