A blocked drain is a problem. At best it is a significant inconvenience; at worst, it can be a hazard resulting in considerable property damage. You can avoid this by keeping your drains flowing smoothly.
Clearing a blockage
If you act quickly in the event of a blockage, you may be able to avoid a costly repair. Clearing a blockage may be done as simply as by pouring boiling water down the drain or putting bicarbonate of soda followed by vinegar into the drain.
Another simple but effective method for dislodging minor clogs is to use a plunger. If none of these methods work, you can try a chemical drain cleaner; however, these are best used sparingly, as they are bad for the environment and frequent use can damage your pipes.
If these suggestions fail, you will need to call in a professional. The cost of this will depend on how easy it is to clear the blockage. If they can clear it with a plumbing snake, the cost is moderate; if it is unclear where the blockage is, they can use a camera to locate it. Check online listings and reviews to find a good company in your area; for example, if you are in Loughborough, search for CCTV drain survey Loughborough to find companies such as Wilkinson Environmental.
Avoiding a blockage
The best way to keep your drains flowing smoothly is to avoid blockages in the first place. Be careful of what goes into your drains. Toilets are for human waste and toilet paper only, so do not flush sanitary products, wipes, or anything else. Use a drain cover to prevent hair or other objects from clogging up sinks, and do not pour cooking oil, fats, or other grease down the drain.
Blockages can also be caused by tree and plant roots invading the drains. Good management of your garden can keep these at bay.
Even if all seems well, pouring boiling water down your drain once a week can help deal with small clogs before they become a big problem.
