Blocked drains are one of the most common (and inconvenient) plumbing problems that we get call outs for. When a drain is blocked, the whole household comes to a standstill until it is fixed and more often than not, it requires professional attention. This week, we take a look at some of the most common causes of blocked drains.

Tree roots and leaves

Tree roots and leaves are two of the most common causes of blocked drains. Although there is little you can do about the roots, you can minimise the amount of leaves that are washed down your drain by sweeping up leaf litter and other debris as it falls during the autumn months.



Everyone sheds hair, and modern drainage is designed to be able to handle minimal amounts of hair provided it receives regular cleaning. However, if you neglect to clean your drainage pipes on a regular basis, the hair and soap scum can build up, eventually causing a complete blockage that needs professional attention. Avoid this problem by removing the cover to your shower and bathroom sink drains once a month and removing any gathered hair.


Grease and fat

When anything with fat or grease content is poured down the drain, it sticks to the interior wall of the pipe and builds up over time, eventually creating a complete blockage that lets no water through. Treating your drain with an unclogging product on a regular basis is one way of breaking down this build-up, but an even easier way to avoid this type of obstruction is to be more mindful of what you pour down the sink and using the bin to dispose of lipids like oil, diary products and grease.

Shoddy workmanship

Always hire a fully licensed, reputable plumber if you need to undertake any sort of significant drainage installation work. Whilst it might look like a simple task that you can YouTube the instructions for, drainage installation requires expert engineering knowledge and there are a lot of things that can go wrong if the installer doesn’t know what they’re doing.
