Don’t let fat be a drain on your Christmas expenses

Who doesn’t like to tuck into a good roast on Christmas Day, especially one with all the trimmings like pigs in blankets and roast potatoes cooked in goose fat? But did you know it could all end in disaster if the fat, oil and grease (FOG) from cooking your Christmas feast aren’t disposed of properly?

When fat is poured down the drain or sink at a temperature above its melting point, it will then cool and solidify. It can form deposits that restrict the flow and cause blockages in your drain or your neighbours’ drains.

Blocked drains can cause:

  • Problems flushing the toilet
  • Issues draining water from sinks and baths
  • Bad smells


Not to mention the cost of having your drains cleared by a professional, should be blockage be something you cannot deal with yourself.

Paul Harmer, Lead Technical Consultant for the Chartered Institute of Plumbing & Heating Engineering (CIPHE) said “The best way to deal with FOG is to let it solidify and put it in a disposable container (like a used margarine tub or yogurt pot) and then put it in the bin. It may seem like common sense but unfortunately people pouring cooking fats into the kitchen sink cause the majority of blockages in drains.

“If you do experience a blockage, which you suspect may be due to FOG, empty out any surplus water remaining in the sink, add some washing up liquid and pour boiling water from a kettle onto the sink outlet. This should soften any hardened fats then turn on the hot tap to flush any deposits through.

Alternatively, you could use soda crystals (follow directions on box). Hopefully, the added washing up liquid or soda may help to prevent solidification. If this does not clear it, then call a professional.”
