It’s likely that most households will experience blocked drains at some point. Sadly, many people remain unaware of the causes of drain blockages. Here, Stu Brock, Manager of Drain Doctor Bedford & Milton Keynes outlines some of the most common causes:

  • Grease and Fats: these items are often poured down kitchen sinks, and are soon forgotten about. However, once they are poured into a drain they stick to the pipes and over time build up, causing water to clear more slowly, leading to eventual blockage. This problem is easily avoided by not pouring such items into sinks and drains, but discarding them with the main household waste.
  • Hair: the build-up of hair in plug holes is a contributing factor to blocked drains. If left unchecked, a mass of hair from bath and shower water will act like a net and catch other debris in the water. Hair traps should be used and checked/cleared frequently to ensure this kind of blockage does not occur.
  • Trees and Leaves: Usually more of a problem in autumn, fallen leaves can easily block drains if gardens are not cleared. In addition, tree roots, which naturally grow towards water sources, can eventually crack pipes and grow within pipes. It is best to avoid planting certain varieties of tree and shrub within 10m of drain runs, and to consider moving plants which grow too large in the vicinity of drain runs.
  • Foreign Objects: When foreign objects such as nappies, toilet rolls, toys or soap bars and fats are flushed down the toilet a drain system will quickly become blocked, either as a direct result of the size of the item or because they become lodged in a pipe and cause hair, leaves, grease etc. to accumulate around them. Young children are often found to be the culprit of blocked toilets – be vigilant!
