5 Plumbing Jobs You Should Never DIY

3 minute read

A man struggles with a leaking kitchen sink and possible hot water failure, water spraying everywhere, while a woman in the background makes a phone call. Text reads: "When DIY Turns Into a Disaster" and "Turbo Plumbing Solutions.

DIY projects can be great for saving money and learning new skills, but plumbing is not an area where guesswork pays off. One small mistake can lead to major water damage, safety risks or repairs that cost far more than hiring a professional in the first place.

At Turbo Plumbing Solutions, we repair DIY attempts every week. Here are the five plumbing jobs that should always be handled by a licensed technician and why taking them on yourself can put your home at risk.


1. Hot Water System Repairs and Installations

Hot water systems operate under pressure and involve electrical or gas components. Any incorrect adjustment can lead to dangerous pressure build ups, electrical faults or complete system failure. We have seen many units damaged beyond repair due to incorrect DIY fixes on valves, thermostats or wiring.

If your hot water system is leaking, not heating or making unusual noises, step back and let a licensed plumber assess the issue safely.


2. Sewer and Drain Blockages

Blocked drains might seem simple, but without proper inspection you cannot see what is happening inside the line. Forcing store bought chemicals or basic tools into a sewer line often makes the blockage worse or damages the pipe.

Roots, collapsed sections and foreign objects all require the right equipment and the correct technique. Our CCTV inspections and jetting equipment allow us to clear blockages without causing further damage.


3. Pipe Replacement or Re Routing

Cutting into walls or underground lines without knowing the exact pipe layout can lead to burst pipes, water damage and costly structural repairs. Even small miscalculations can create long term leaks that go unnoticed until major damage occurs.

A licensed plumber uses pressure testing, pipe tracing and professional fittings to ensure that every connection is secure and compliant.


4. Installing or Repairing Pressure Valves

Pressure control valves and temperature relief valves are essential safety devices in your plumbing system. These valves regulate pressure and prevent explosions or tank ruptures. Incorrect DIY repairs or replacements can result in uncontrolled pressure build up or complete system failure.

Professionals use the correct valve ratings and installation techniques to keep your system safe and compliant. These components should never be adjusted without proper training.


5. Toilet and Bathroom Fixture Installations

Replacing taps or toilets might look simple, but incorrect seals or poor alignment often cause hidden leaks. These leaks can damage flooring, wall cavities and structural timber over time.

We replace these fixtures with the correct seals, secure fittings and pressure tests, ensuring the installation is water tight and safe.


Protect Your Home by Choosing Professionals

DIY plumbing mistakes are more expensive than they first appear. Water damage spreads quickly, electrical risks increase under moisture, and incorrect fittings can cause slow leaks that are difficult to trace.

Hiring a professional is the safest and most cost effective choice. Our team uses the right tools, the correct testing methods and industry approved installation standards to protect your home and keep your plumbing operating safely.
