    Plumbing mistakes to avoid

    May 20, 2025

    Repairing things in the house can be satisfying—sometimes, it is a good idea. Is a cabinet hinge loose? Use a screwdriver. Is a door creaking? Some oil can be a miracle. But with plumbing, things are not always so simple.

    At Magnificent Plumbing & Rooter, we’ve seen far too many instances where fantastic do-it-yourself plumbing repairs resulted in costly damage, wasted water, and even costly home insurance claims. We clarify that some plumbing jobs should always be left to the experts.

    Here are six plumbing tasks you shouldn’t attempt to do yourself—and why it’s worth hiring a licensed plumber to save you money, time, and a lot of headaches.

    1. Big Pipe Changes or New Installations

    Replacing an old pipe may appear to be a simple job—until you go to open the wall, miscalculate the size of the pipes, or overlook the water pressure requirement. Incorrectly installed pipes can result in leakages, contaminated water, or ruptured pipes that are very expensive to repair.

    Sometimes, pipe replacement necessitates cutting concrete, drywall, or floors—and may entail local permits and inspections. We at Magnificent Plumbing & Rooter ensure that all pipe installations are done as per the regulations and safely to guard your home.

    Why not DIY?

    • Incorrect pipe size or usage
    • Potential code infractions and fines
    • Risk of hidden leaks or water damage

    2. Installing or repairing a water heater

    Both tank-type and tankless water heaters are advanced systems that are either gas or electric. They are hazardous if not handled carefully. One slight misstep during installation can lead to gas leaks, carbon monoxide poisoning, or even severe burns due to overheating.

    Repairing a water heater also includes the knowledge of pressure relief valves, thermostat adjustment, and sediment buildup—something a typical homeowner would not want to try.

    Why go DIY?

    • Danger of gas line and fire risk
    • Danger of leaks and water damage
    • Risk of losing the manufacturer’s warranty.

    3. Repairing Sewer Line

    A ruptured sewer line requires experts to repair it. Attempting to fix yourself, such as using a rent-a-scope or flushing chemicals down your drain, can compound the issue—particularly if the clog is deep in the main line or the result of tree roots, rust, or cracked pipes.

    Sewer line repair generally involves excavation, permits, and specialized video inspection equipment. At Magnificent Plumbing & Rooter, we diagnose and repair sewer issues with non-invasive technology efficiently and safely.

    Why not DIY?

    • Risk to property contamination or damage
    • Exposure to raw sewage and health risks
    • More problems arise from incorrect diagnoses.

    4. Kitchen or Bathroom Plumbing Renovation

    Remodeling your home? That’s wonderful—but if the job involves the relocation of sinks, bathtubs, or dishwashers, plumbing expertise is not a choice. Fixture relocation involves pipe reconfiguration and correct slope, drainage, and venting—all critical to long-term performance.

    Most DIY remodelers disregard plumbing codes, resulting in inspection failures or subsequent insurance problems. Our professionals help ensure your remodel is done right—the first time.

    Why go DIY?

    • Risk of leakages and poor drainage
    • Code infractions resulting in project delays.
    • Long-term issues are created by poor planning.

    5. Installation of gas lines for appliances

    Plumbing isn’t all about water—gas lines are also. Installing or repairing a gas line for a stove, dryer, or water heater has exceptional qualifications and equipment. Mistakes are costly and can also be extremely hazardous.

    Never attempt to install gas connections or shift gas pipes by yourself. The risk of explosion and carbon monoxide poisoning is exceptionally high.

    Why go DIY?

    • Immediate threat to life and property
    • Risk of explosion, fire, or gas leakage.
    • Legal responsibility in case of an error

    6. Slab Leak Detection and Repair

    A slab leak is a pipe leak that supplies water beneath your house’s concrete floor. Slab leaks are tricky to find and need specialized equipment to fix. If left unfixed, slab leaks will deteriorate your foundation and badly damage your house.

    Experimenting now is not the time. Magnificent Plumbing & Rooter utilizes sound and heat detection equipment to locate slab leaks precisely and repair them with minimum disruption to your home.

    Why not DIY?

    • Inability to determine the exact leak location
    • Risk of harming the foundation
    • Unnecessary costs because of lackluster repair work

    The Cost Of Doing It Yourself: Plumbing

    It may appear to be saving money doing it yourself. But with plumbing, fast fixes have down-the-road consequences. Water damage, mold, inspection failure, and even lawsuits can ensue, making the cost of DIY most of the time not worth the savings.

    Professional plumbers don’t just bring tools along—experience, expertise, and assurance that the job will be done correctly and safely come along as well.

    When Do You Call The Experts?

    If you notice any of the plumbing issues or are unsure, don’t risk your home. The expert staff at Magnificent Plumbing & Rooter is ready to assist.

    We offer:

    • Bonded, insured, and licensed service

    Remember DIY Isn’t Always the Answer

    DIY is great for most things around the house—but when it comes to plumbing, it’s just as crucial to recognize when to leave it to the professionals as it is to understand how to loosen a bolt. One small error can cause a huge issue.

    Leave your plumbing issues to Magnificent Plumbing & Rooter. We’ll get dirty so you can focus on what matters most—your home, family, and peace of mind.
