Plumbing issues can bring daily life to a halt and if ignored, can lead to major repairs and expensive water damage. At Level Plumbing Lithgow, we believe the best way to protect your home is through prevention. Below, we break down the most common plumbing problems Australian homeowners face, along with practical tips to stop these issues before they start.
1. Leaking Taps
The Issue: A dripping tap might seem harmless, but over time it can waste thousands of litres of water and add unnecessary cost to your water bill. If left too long, leaks can also cause damage to surrounding fixtures.
Common Causes:
- Worn washers or O-rings
- Loose or damaged internal parts
- Corroded valve seats
How to Prevent It:
- Regular checks: Inspect taps frequently and replace worn parts like washers as soon as you notice a drip.
- Use aerators: Installing tap aerators reduces water flow and helps minimise wear.
- Tighten fittings: Make sure connections are snug. Plumber’s tape can help seal threaded joints.
- Book a professional inspection: A licensed plumber can detect developing issues before they turn into major leaks.
2. Blocked Drains
The Issue: Clogged drains can cause unpleasant odours, slow emptying sinks, and in severe cases, sewage backing up into the home.
Common Causes:
- Hair, soap, or grease build-up
- Objects accidentally flushed or washed down drains
- Tree roots breaking into underground pipes
How to Prevent It:
- Install drain covers: Mesh screens catch hair and debris in bathrooms and kitchens.
- Dispose of grease properly: Pour oils and fats into a container, not down the sink.
- Monthly maintenance: Use a natural drain cleaner like vinegar and baking soda, followed by hot water, to clear minor build-up.
- Professional cleaning: A full drain clean every couple of years helps prevent stubborn blockages.
3. Running Toilets
The Issue: A constantly running toilet can waste up to 200 litres of water a day—without you even noticing. This is often caused by worn or misaligned internal parts.
Common Causes:
- Faulty or worn flapper
- Incorrect float level
- Damaged fill valve
How to Prevent It:
- Inspect components: Replace worn flappers and check for cracks in the cistern or toilet bowl.
- Adjust the water level: Water should sit about 2.5cm below the overflow tube.
- Do a dye test: Add food colouring to the tank. If colour appears in the bowl without flushing, you have a leak.
- Routine servicing: Have a plumber check the system periodically to ensure everything is working efficiently.
4. Hot Water System Problems
The Issue: Lack of hot water, rumbling noises, or leaks from the tank are signs of a struggling hot water system.
Common Causes:
- Sediment collecting inside the tank
- Failing heating elements
- Corrosion and rust
How to Prevent It:
- Annual flushing: Removing sediment keeps your system running efficiently.
- Check temperature settings: Keeping the thermostat around 60°C helps protect against scalding and bacteria growth.
- Inspect for leaks: Regularly check for water pooling or rust staining around the unit.
- Plan ahead: If your system is 10 years or older, start considering an upgrade for improved safety and efficiency.

5. Pipe Corrosion
The Issue: Pipes naturally wear over time. When corrosion sets in, pipes can weaken, leak or burst, resulting in major water damage.
Common Causes:
- Old or outdated pipe materials
- High mineral or acidity levels in water
- Incorrect installation
How to Prevent It:
- Choose modern materials: When replacing pipes, opt for corrosion-resistant choices such as PEX or PVC.
- Monitor your water: Metallic taste or discoloured water may indicate corrosion—get it tested.
- Regular inspections: Professional plumbing check-ups detect corrosion early and help avoid serious failures.
