Common Causes of Blocked Drains

Grease and food waste are major culprits in kitchen sinks. Over time, they build up and restrict water flow. In bathrooms, hair and soap residue are the most common causes of blockages.


Tree Roots

Tree roots are a major issue in older Sydney suburbs. Roots can enter pipes through small cracks and expand, causing serious blockages.


Foreign Objects

Items like wipes, sanitary products, and paper towels should never be flushed, as they can easily cause blockages.
