Overflowing toilets and sinks are not just inconvenient; they can also cause significant damage if not addressed promptly. For homeowners in Sydney, understanding how to prevent these issues—and knowing what to do when they arise—can save both time and money.
Common Causes of Overflows
In many Sydney homes, sink and toilet overflows are often caused by blocked pipes or sewer vents. Common culprits include hair, food scraps, grease, and soap buildup in sinks. Toilets frequently back up due to flushing inappropriate items or simply having blocked pipes.
How to Prevent Overflows
1. Book Regular Maintenance
Routine plumbing inspections and drain cleaning can help catch issues early before they escalate into emergencies. Regular maintenance is essential for keeping your plumbing system in top shape.
2. Watch What You Flush or Drain
Only flush toilet paper—never wipes, sanitary products, or paper towels. In the kitchen, dispose of oils and food scraps in the bin, not the sink. This simple habit can significantly reduce the risk of blockages.
3. Inspect Your Toilet Hardware
Check that your toilet’s flapper, float, and fill valve are functioning properly. Replacing worn parts can prevent malfunctions and flooding. Regular checks can save you from costly repairs down the line.
What to Do During an Overflow
If water starts to rise, follow these steps:
Turn Off the Water: Quickly shut off the valve behind the toilet or under the sink to stop the flow.
Try a Plunger: Often, a plunger can loosen small blockages and restore normal flow.
Avoid Harsh Chemicals: Chemical drain cleaners can damage your pipes and worsen the problem—especially in older Sydney homes.
When It’s Time to Call the Pros
