An unopened can of lager is among the strange things that have been found blocking sewers in the North East.
The full can of Foster's was found down a sewer in Northumbrian Water's network in South Tyneside.
The organisation, which is supporting a campaign urging people not to use their toilets as a bin, posted a message on Twitter about the lager.
It said: "We don't think it was a ‘Good Call’ flushing this can of unopened Foster’s down one of our sewers, which caused it to block up.
"Howay man... What a waste of lager."
Northumbrian Water says their engineers have found a string of weird and wonderful items over the years. Some of them may have been flushed down toilets while others may have entered the sewer network through manhole access points.
The items have included a Peppa Pig toy and a shotgun cartridge near Houghton-le-Spring, a mobile phone in Sunderland, a full sized curtain rail that someone managed to get down a drain in Jesmond, a set of false teeth found in a sewer pipe in Stanley and a pair of boxer shorts in Bournmoor.
On one occasion, a Saturday night outfit including a men's shirt, pair of jeans and socks were found blocking a sewage pumping station in Durham.
And in 1992, a seven-foot python was discovered at a sewage treatment site in Newcastle.
Northumbrian Water, which is backing sewer blockage awareness month, Unblocktober, says householders should only flush the 3P's - pee, paper and poo - down the loo.
Wrongly flushed items, such as wet wipes, are one of the biggest causes of blockages as they usually clog up inside the pipe or meet with forming fatbergs.
Fatbergs form when fats, oils and grease are poured down the drain, and harden.
Items such as wet wipes, nappies, cotton buds, condoms, and sanitary products that are disposed of down the toilet instead of being put in a bin, can lead to the sewer network backing up.
Richard Warneford, Northumbrian Water's wastewater director, said: "We are proud to support the national campaign, Unblocktober, to help raise awareness and tackle the industry-wide problem of sewer blockages.
"Wet wipes are one of the biggest causes of blockages for us and we really need our customers' help to wipe out the flushing of wipes.
"Despite wet wipes being promoted as ‘flushable' they rarely are, as they may leave your toilet bowl when flushed but can clog up householders' plumbing and can also cause blockages in our network of sewer pipes.
"Blockages can have devastating consequences to people's homes being flooded and the environment being polluted, which is so saddening to see."
Last year, Northumbrian Water cleared around 12,000 blockages within its 29,000 kilometres of sewer network across the North East.
The task of clearing blockages costs the water company around £1m every year and causes customers to experience flooding in their homes.
