Find out what you can do to prevent sewer blockages by being aware of what you put down the sink and toilet.

Bag it and bin it

Help us to help you - Keep the sewers flowing by following our top tips:

Don’t pour fats, oils and greases down the sink or the toilet – even the tiniest amount can cause problems. They may be in liquid form going down, but they quickly solidify when they meet the cold sewer walls (even if you pour hot water down after). The fats stick to the side of the sewer forming a concrete-like solid that attracts other debris, eventually causing a blockage.

Top tip: Wait for fat to cool after cooking and pour it in to an empty margarine tub or a GunkPot, then when it’s full throw it in the bin.

Only human waste, toilet tissue and a small amount of household cleaning products should be flushed down the toilet. Don't flush:

  • sanitary products
  • kitchen roll
  • cleansing wipes
  • baby and facial wipes
  • nappies
  • cotton buds 

Top tip: Instead use nappy or sanitary bags then put them in the bin.


Avoid nasty blockages in your kitchen by using a GunkPot to bin leftover fats, oils and grease from cooking.

The benefits of the GunkPot:

  • Save money - avoid the cost of repairing blocked pipes by storing leftover fats, oils and grease in your GunkPot,instead of pouring them down the sink.
  • Easy to use - simply ensure all fats,oils and grease are cooled to room temperature before carefully pouring into the GunkPot.
  • Functional - Use the GunkPot to store the fat and, once full, dispose of the fat in the bin and reuse it.
