What Items Should I Avoid Flushing Down the Toilet or Washing Down the Sink? 

Flushing inappropriate items down the toilet and sink can lead to blocked sewers, environmental pollution, and even flooding.  

You should only flush waste and toilet tissue down the toilet.  

Wipes 

In a 2017 study, wipes made up around 93% of the material causing the sewer blockages.  

Wipes Include: 

• Baby wipes 

• Cleaning wipes 

• Toilet wipes 

• Makeup wipes 

Even those labelled as “flushable” or “biodegradable” do not break down quickly, often causing sewer blockages. 

As well as wipes, don’t flush; cotton wool and cotton buds, paper towels, dental floss, cigarette butts, or sanitary products down the toilet.  

Fat, Oil, and Grease 

Pouring fat, oil, or grease down the toilet or drain can lead to the formation of fatbergs – solid masses that block sewers. In the UK, it is illegal to dispose of these substances into public waste pipes because of the significant damage they cause. 

To properly dispose of cooking oil and fat, allow it to cool first, then place them in a food bin or general waste bin. 

In addition to oil and fat, refrain from pouring gravies, coffee grounds, or rice down your sink.
