  2. Blocked drains are one of the most common plumbing problems

    Perth households face. Whether it’s a slow-draining shower, a kitchen sink backup, or water pooling outside near your garden, these issues can bring your daily routine to a halt. Worse, if left unchecked, blockages can lead to burst pipes, water damage, or even health hazards. The good news? With a little awareness and regular maintenance, you can prevent most blockages — and deal with them before they cause expensive damage. Introduction
  3. Why Drains Block Up in Perth If you’ve noticed your

    drains blocking up regularly, it’s a sign you should call a residential plumber in Perth for a professional inspection before the damage becomes extensive. A blockage occurs when something obstructs the water’s path inside your pipes. While clogged drains happen everywhere, Perth has a few unique factors that make them more common: S A N D Y S O I L O L D E R P I P E S Y S T E M S T R E E - L I N E D S T R E E T S A N D G A R D E N S H I G H M I N E R A L C O N T E N T I N W A T E R This can shift and put pressure on underground pipework, leading to cracks where debris or roots can enter Many older Perth homes still have clay or galvanised steel pipes that are more prone to damage and corrosion. Popular Perth trees like Jacarandas and Figs have aggressive roots that can seek out water sources in pipes. Over time, mineral build-up can narrow your pipes, especially if they’re already partially blocked.
  4. Hair Strands can wrap around themselves and combine with soap

    residue to form stubborn clumps. Showers, bathtubs, and bathroom basins are especially prone. Hair Build-Up 6 Common Causes of Blocked Drains When grease, fat, or cooking oil is poured down the sink, it cools and solidifies inside the pipes. making clogs almost inevitable. Grease and Cooking Oils Tree roots are surprisingly powerful. They can enter pipes through tiny cracks, expanding over time until they completely block the flow or cause the pipe to collapse. Tree Root Damage 💡 Prevention Tip: Install a drain strainer in showers and basins, and clean it every few days. 💡 Prevention Tip: Let oils and fats cool, then scrape them into the bin. For mild build-up, flush the kitchen drain with boiling water and dishwashing liquid every week. 💡 Prevention Tip: If your yard has large trees, arrange a CCTV drain inspection every couple of years. This allows plumbers to detect and cut roots before they cause major damage.
  5. Items like wet wipes, sanitary products, nappies, and even excessive

    toilet paper can block drains quickly. Foreign Objects 6 Common Causes of Blocked Drains Bar soaps, especially those with added fats, can create a hard residue (soap scum) that clings to pipes. Over time, this narrows the pipe and slows water flow. Detergent Residue If your plumbing was installed with incorrect slope (fall) or poor-quality fittings, blockages will occur more often. Water may pool in low spots, allowing debris to settle and harden. Poor Pipe Installation 💡 Prevention Tip: Keep a small bin in the bathroom for non- flushables, and remind household members to only flush toilet paper and human waste. 💡 Prevention Tip: Switch to liquid soap or body wash where possible. In laundry sinks, use liquid detergents and run hot water for a minute after each wash to flush away residue. 💡 Prevention Tip: Have a licensed Perth plumber inspect the installation. Sometimes a small adjustment can eliminate years of recurring issues.
