According to an expert plumber from MyBuilder.com, blockages in kitchen sinks are caused by everyday products, but many are not aware of what liquids are problematic.

Mike Flook, a plumber from the company, said: “While it may seem that liquids like creamy drinks or leftover gravy could be washed down the sink, the reality is that they can cause serious issues, especially if it’s a repeated action.

“The result can be that, depending on the product and where you tipped it, you could face blocked toilets or sinks.

“While this is a pain at any time of the year, at Christmas when plumbers can be hard to come by, it is doubly frustrating and costly.

“However, there are steps you can take to avoid making these mistakes, as well as emergency actions you can take to help mitigate any disasters should you have accidentally flushed or poured something you shouldn’t.”

Baileys

Cream liqueur drinks, such as the popular Baileys, can be a problem for your plumbing at Christmas.

According to the expert, drinks such as Baileys have a large fat content and fall into the category of FOG (fats, oils and greases).

The expert said: “FOG should never go down the sink, as it sticks to pipes and can cause blockages. It’s also what’s responsible for fatbergs' in our sewers."

Turkey fat

The plumber explained: “As with Baileys, turkey fat is classed as FOG. Half the population admit to pouring FOG down the drain, but don’t be one of them.

“The problem with pouring leftover fat down the drain is it will cool, which can lead to blockages and fatbergs in your pipes.

“Calling out a plumber on Christmas Day is not easy - both in terms of availability and on the wallet.

"Emergency callouts can be four times as expensive as a regular one - and even more at Christmas.”

Coffee grounds

If you’ve got guests over throughout the festive period and are providing them with fresh coffee, it may seem quick and easy to flush coffee grounds down the sink.

However, according to the expert, they can clump together in the U-bends of the pipes and create blockages.

If you accidentally pour any of these items down the sink, immediately run the hot water and add soap to the hot water to help remove the blockages.

The plumber noted: “Do not use chemicals. Drain unblockers are often ineffective against FOGs, and can cause damage to your pipes in the process.

“A plunger is likely to be more effective, and is gentle, so ensure you have one in the house just in case.”
