🚧 7 Common DIY Plumbing Mistakes to Avoid

🚰 1. Over-Tightening Plumbing Connections

🔹 Why It’s a Problem: Many homeowners think that tighter is better when it comes to pipes and fittings, but over-tightening can crack fittings, strip threads, and cause leaks over time.

✔ DIY Tip: Hand-tighten fittings and use a wrench with caution to avoid damage.

✔ Call a Plumber If: You notice drips, leaks, or pressure issues after a DIY repair.

🛠 2. Using Chemical Drain Cleaners Too Often

🔹 Why It’s a Problem: Store-bought chemical drain cleaners may seem like an easy fix for clogged drains, but they can corrode pipes, leading to leaks and long-term damage.

✔ DIY Tip: Try natural alternatives like a baking soda and vinegar solution or use a plunger before reaching for chemicals.

✔ Call a Plumber If: You have repeated drain blockages, slow drainage, or gurgling sounds in pipes. This could indicate a serious blockage deeper in your system.

🚽 3. Flushing the Wrong Things Down the Toilet

🔹 Why It’s a Problem: Many homeowners flush non-biodegradable items, thinking they will break down like toilet paper. Items like wipes, paper towels, cotton buds, and sanitary products can cause major blockages in your sewer line.

✔ DIY Tip: Only flush toilet paper and human waste—everything else belongs in the bin!

✔ Call a Plumber If: Your toilet is slow to drain, frequently clogged, or backing up.

🔥 4. Incorrectly Installing a Hot Water System

🔹 Why It’s a Problem: Installing a hot water system yourself is not only illegal in Queensland, but it can also cause leaks, gas hazards, and serious safety risks if done incorrectly.

✔ DIY Tip: Don’t attempt to install or repair a hot water system yourself!

✔ Call a Plumber If: Your hot water system is leaking, not heating properly, or showing error codes.

🚿 5. Using the Wrong Pipe Materials

🔹 Why It’s a Problem: Some homeowners mix different types of pipes, such as PVC, copper, and galvanized steel, without considering compatibility. This can cause corrosion, leaks, and pressure issues.

✔ DIY Tip: Always use the correct fittings and materials for your plumbing system.

✔ Call a Plumber If: You have low water pressure, leaks, or unusual noises in your pipes.

💦 6. Ignoring Small Leaks

🔹 Why It’s a Problem: A tiny drip may not seem like a big deal, but over time, it can waste thousands of liters of water and lead to mold growth, structural damage, and higher water bills.

✔ DIY Tip: If you notice damp patches, mold, or unexplained high water bills, don’t ignore it!

✔ Call a Plumber If: The leak persists after DIY attempts or is inside walls, under floors, or in the ceiling.

🛑 7. Forgetting to Turn Off the Water Supply Before a Repair

🔹 Why It’s a Problem: Many DIY plumbers forget to shut off the main water valve before replacing a tap, toilet, or pipe. This can result in flooding, water damage, and costly repairs.

✔ DIY Tip: Always locate your main water shut-off valve before starting any plumbing repair.

✔ Call a Plumber If: You accidentally flood your bathroom or kitchen and need emergency assistance.

🔧 When to Call a Professional Plumber

While some basic plumbing maintenance can be done yourself, the following jobs should always be handled by a licensed plumber:

  • ✔ Blocked Drains & Sewer Issues – Professional drain cleaning prevents damage to your pipes.
  • ✔ Hot Water System Repairs & Installations – Required by law to be done by a licensed plumber.
  • ✔ Burst Pipes & Major Leaks – To prevent flooding and structural damage.
  • ✔ Gas Plumbing & Fittings – Gas leaks are dangerous and require professional repairs.
  • ✔ Toilet & Tap Installations – Avoid incorrect fittings that can cause leaks over time.

🔹 💡 Tip: If you’re unsure whether a job requires a plumber, it’s always safer to call and ask!
