A blocked pipe is a common household problem that can cause significant inconvenience in everyday life. There are several methods to unblock a pipe, depending on the severity of the blockage. Mild blockages can often be treated yourself with a traditional rubber pump, baking soda and vinegar or hot water. More serious blockages require professional help and special tools. In this article, we'll go through the signs, causes and solutions to clogs in your home.
How do you know if a pipe is blocked?
A blocked pipe is indicated by several clear signs. Water drains slowly or not at all, there are gurgling noises and an unpleasant smell. In more serious cases, water can back up into the sink, shower or toilet.
Slowly flowing water is usually the first sign of an incipient blockage. If you notice that your sink or shower drain is draining slower than usual, you should react quickly before it gets worse. A gurgling sound is made when water tries to get past a partially blocked point and air is vented from the drain.
An unpleasant smell usually indicates a build-up of organic matter in the pipe. Odour problems are often exacerbated in damp rooms and in warm weather, when bacteria break down the residues in the pipe. If several drains in the same household are behaving strangely at the same time, it could be a more serious blockage in the main sewer.
What causes a pipe to block?
The most common causes of pipe blockages are hair, grease, soap residues, food waste, foreign objects and mineral deposits. In a bathroom drain, hair easily becomes entangled with soap, forming a tight clog. In the kitchen drain, grease congeals on the walls of the pipes and collects other waste.
Hair is particularly problematic because it does not break down easily in water. It sticks to the unevenness of pipes and forms a web to which other substances become trapped. Soap and shampoo contain fats that combine with the hair and harden over time.
In the kitchen, the main problem is grease, which flows down the drain as a liquid but solidifies in colder pipes. Coffee grounds, tea grounds and food waste make matters worse. The toilet drain only holds toilet paper and human waste, other products such as wet wipes can cause a serious blockage.
In hard water, limescale deposits can gradually narrow pipes, especially in hot water pipelines. This is a slow process, but eventually it can cause significant flow problems.
How to open a slightly blocked pipe yourself?
You can often open a mild blockage yourself using simple methods. Start by pumping with a rubber pump, which creates pressure and suction at the site of the blockage. If that doesn't work, try baking soda and vinegar: pour half a cup of baking soda down the drain, add a cup of vinegar and leave for 30 minutes before flushing with hot water.
The rubber pump works best when there are a few centimetres of water in the pool. Cover the overflow hole with a wet rag to effectively apply pressure to the blockage. Pump vigorously up and down 15-20 times. This method is particularly suitable for blockages caused by hair and soap.
Baking soda and vinegar cause a chemical reaction that removes fat and organic matter. This natural method is safe for pipes and does not harm the environment. Finally, rinse with boiling water, which melts the grease and flushes away the loose particles.
The mechanical drain wrench, or "snake", is a powerful tool for deeper clogs. Gently push it into the drain, rotating it until you feel resistance. Rotate and push alternately until the blockage opens. Finally, flush with plenty of water to ensure that all residue is flushed away.
When do you need a professional when a pipe is blocked?
Professional help is needed when independent attempts fail, blockages recur regularly, several drains are blocked at the same time, or you suspect pipe damage. It's also a good idea to call a professional immediately if the water comes back up or you hear strange noises coming from inside the walls.
Repeated blockages in the same place indicate a deeper problem that cannot be solved by superficial measures. The problem may be in the structure of the pipework, such as an incorrectly installed elbow or a compression. A professional can examine the pipes with a camera and pinpoint the exact location of the problem.
If several drains are blocked at the same time, it is likely to be a blockage in the main drain. This is a serious situation that requires rapid action. A blocked pipe in a home in such a situation can cause water damage if sewage rises to the floors.
Professionals have specialised tools such as powerful pressure washers, long mechanical wrenches and camera inspection equipment. We offer a 24-hour plumber service, and our on-call plumber can arrive quickly if the situation requires. You'll get the first advice on how to prevent damage over the phone.
How to prevent future pipe blockages?
Blockages in pipes can be prevented by regular maintenance and correct operating habits. Install drain filters in all drains to collect hair and food waste. Flush drains with hot water weekly and avoid pouring grease down the drain. Clean drain filters regularly and remove visible hair and waste immediately.
In the kitchen, wipe greasy pans and plates with paper before washing up. Let the grease set and throw it in the mixed waste, never down the drain. Always use hot water and dishwashing liquid to flush the drain after washing greasy dishes.
In the bathroom, brush your hair before you shower to reduce the amount of hair that ends up in the drain. Empty the drain filter after every shower. Once a month, you can do a preventative cleaning with baking soda and vinegar to keep your pipes clean.
The toilet bowl contains only toilet paper and human waste. Wet wipes, tampons, cotton swabs and other toiletries belong in the bin, even if they are marked as flushable. Regular maintenance by a professional can also help identify potential problems before they develop into serious blockages.
In hard water, consider installing a water softener to reduce limescale build-up. Regular plumbing inspections will help keep your drains in good working order and save on repair costs in the long run. We are on hand to help with both preventative maintenance and acute blockages 24 hours a day.
