If you think clearing up the Christmas dinner mess is going to be bad, spare a thought for these guys...

Over the festivities the two with strong stomachs will endeavour to make sure that the extra fat, oil and grease from the Christmas fayre that some pour down the plug hole won’t clog the sewers and jam pumps at sewage works.

Fred said: “It’s easy to assume that the warm grease and fat left over from your turkey would be okay to dump down the sink, as long as you wash it down with a lot of hot soapy water.

“But the fat and grease will cool and solidify, building up and blocking the drain or sewer.

“Better to wipe any greasy pans with kitchen roll and then put it in the bin, or pour large amounts of grease into a pot or one of the free fat traps that Severn Trent provides to its customers.”

And Aaron said: “Drains from the home are the owner’s responsibility, are only a few centimetres wide and are meant to take water, loo roll and human waste only.”
