10 Things You Should Never Flush Down Your Drains

Dec 12, 2023 | News

At times, due to our hectic routines or occasional oversights, we’ve all inadvertently let something slip down the drain. Invariably, this split-second action leads to instant regret! The repercussions of blocked drains are steep, potentially costing hundreds or thousands of pounds and causing significant harm to the drainage system. Moreover, it’s essential to bear in mind that most of what disappears down our drains ultimately finds its way to landfills, potentially cycling back into our lives through drinking water or food. Being mindful of what enters our drains not only prevents blockages and environmental strain but also minimizes our ecological footprint.

Here are 10 items to be cautious about:

  1. FOG – Fats, Oils, and Cooking Grease: These substances solidify as they cool, leading to drain blockages. Solidify them in a container before disposal in the trash.
  2. Nappies: Highly absorbent and expandable, they can clog drains and should not be flushed, especially if labelled “flushable but not septic safe.”
  3. Bones and Pits: Prevent these from entering drains by using filters while processing ingredients in the kitchen sink.
  4. Egg Shells: These can create granulated waste that accumulates in drains, causing blockages over time, similar to potato peels and other food waste.
  5. Tampons and Sanitary Napkins: Designed to expand, these items cause blockages and environmental harm due to their non-dissolving nature.
  6. Coffee Grounds or Beans: Accumulating in drains over time, these moist grounds contribute to blockages, often unnoticed.
  7. Chemicals like Fertilizer, Insecticides, and Pesticides: Never flush these down drains as they can harm ecosystems and wildlife.
  8. Condoms: Non-compostable and prone to tangling with other items, condoms cause pipe blockages and environmental damage in landfills.
  9. Wipes: Even if labelled as “flushable,” wipes with plastic components are non-degradable and cause severe drain blocks.
  10. Flammable or Explosive Materials: Never dispose of these in drains, as they pose serious safety risks and can ignite within pipes. Also, avoid dumping paint in toilets to prevent hardening and blockages.


Blocked drains can lead to a cascade of problematic consequences, ranging from inconvenience to substantial financial burdens and environmental hazards. Initially, they cause immediate disruptions in daily life, leading to slow drainage, foul odours, and potential backups of wastewater. If left unattended, these issues can exacerbate, resulting in structural damage to properties due to flooding or leakage. The financial toll is significant, as resolving such blockages often requires professional intervention, involving costly repairs or replacements of pipes and drainage systems.

Moreover, blocked drains contribute to environmental concerns by contaminating water sources, causing pollution, and disrupting ecosystems when untreated sewage or debris seeps into natural habitats. The cumulative impact encompasses both personal inconvenience and broader environmental implications, highlighting the multifaceted repercussions of neglecting proper drain maintenance.
