Why Do My Drains Keep Blocking? Common Causes in Bentleigh

Blocked drains usually don't happen without warning. Slow drainage, bad odours, gurgling pipes and recurring blockages are all signs that something is restricting the flow of water. While some minor blockages can be cleared temporarily, recurring drain problems often require professional attention to identify and fix the underlying cause.

A blocked drain is one of the most common plumbing problems homeowners face. Understanding what causes drains to block can help you prevent future issues and know when it's time to call a plumber.

Tree Roots

Tree roots naturally seek out moisture and can enter underground pipes through small cracks or joints. Once inside, they continue to grow, restricting water flow and causing recurring blockages.

If your drains continue blocking despite repeated clearing, tree roots could be the cause.

Grease and Food Waste

Kitchen sinks are a common source of blocked drains. Grease, fats and oils may go down the drain as liquids but quickly harden inside your pipes. Over time they collect food scraps and create stubborn blockages.

Allow grease to cool before disposing of it in the bin rather than washing it down the sink.

Hair and Soap Build-Up

Bathroom drains frequently become blocked by hair, soap residue and personal care products. While these materials may seem harmless individually, they gradually build up and reduce the flow of water.

Installing simple drain strainers can significantly reduce the amount of debris entering your plumbing.

Foreign Objects

Wet wipes, sanitary products, paper towels and other household items should never be flushed down the toilet. Unlike toilet paper, these products don't break down properly and can quickly create major blockages.

Only flush toilet paper and human waste to help protect your plumbing system.

Damaged or Collapsed Pipes

Older properties can develop cracked, collapsed or misaligned pipes due to age, ground movement or previous repairs. These structural issues often lead to recurring drainage problems that won't be resolved with basic drain clearing.

A CCTV drain inspection can identify exactly what's happening inside the pipe without unnecessary excavation.

When Should You Call a Plumber?

If your drains keep blocking, water is backing up, or you notice bad odours or gurgling sounds, it's worth having the problem professionally assessed. Clearing the blockage without addressing the underlying cause often means the issue will return.

Professional equipment and CCTV drain inspections allow plumbers to accurately diagnose the problem and recommend the most effective solution.
