Of all the reasons to call on a plumber, a blocked drain is one of the most common. From foul smells to water that simply won’t drain, blocked sinks are the root cause of all kinds of minor problems. When these issues are allowed to get worse, however, life can quickly become pretty nightmarish.

If you suspect you have a blocked drain, the good news is you may be able to clear it yourself. With our advice, everything will be flowing smoothly in no time.


Blocked drains can be a source of property damage and health problems for people and pets. The early warning signs of a blocked drain are:

Foul smell

The first sign you may notice is an unusual smell. In most cases, this is a sewage-like scent, and you might wander into your bathroom and wonder if someone forgot to flush. Other signs of a blocked drain include:


You’re probably quite used to everything flowing down your drain. As a result, it’s quite alarming seeing water spill back up. If your drain is overflowing, that means you’re facing a blockage.

Gurgling sounds

Gurgling sounds indicate that the water is pooling and pushing against the pipe. If you experience this, it’s often the case that a blockage is a problem.

Slow draining

When emptying your sink or taking a shower, you might notice that the water pools for longer than expected. Usually, the problem worsens rather than getting better by itself, which suggests that the blockage is growing larger.


Although most people use their drains appropriately, it’s quite easy to make mistakes. Occasionally, everyday use results in blocked drains too. Common causes include:

Tree roots

Tree roots won’t be the cause of local drain blockages, but they can disrupt your main sewage system. The root keeps growing until it breaches the pipe and causes a blockage.


Although toiletries are essential, some can cause drain blockages. For example, nappies, baby wipes and sanitary products should not be flushed down the toilet.

Foreign objects

When you have kids, there’s always a risk they’ll flush something unusual down the toilet. Toys and other foreign objects become lodged in the u-bend, resulting in a blockage.

Cooking oil

In no circumstances should you throw cooking oil into the sink, as it’s too viscous to flow freely. Instead, it gathers and clumps together with food debris to cause a blockage.

Food scraps

Much like cooking oil, food scraps don’t belong in your drainage system. This is especially true of coffee grounds.

Mineral Buildup

When minerals such as calcium build up in your pipes, this causes constriction. Although this may not cause a blockage on its own, it does make it easier for other types of blockages to form.


Although liquid soap may not cause drain blockages, solid soap bars can get lodged within pipes until they eventually break down. One way to stop this from happening is to use a mesh wire guard to cover plug holes.


Having long hair is both a blessing and a curse. When you wash it in the bath or shower, you’ll find that some of it drops out. As it does, it mixes in with other substances and becomes a major cause of a blocked drain.

Natural Debris

Natural debris can fall into your outdoor drains, especially when you don’t use gutter guards. This usually means leaves and twigs, although it can include dirt and grit too.

Cat litter

When cat litter is exposed to water it clumps together and then expands. As a result, any cat litter that enters your drain is likely to cause a blockage.
