A blocked drain can cause frustration and should be addressed immediately. With that in mind, we’ve put together a list of signs to look out for when it comes to blocked drains.

Slow draining

Blockages can occur when your bathtub or sink drains slower than usual. This is one of the most common signs of a blocked drain. It could be caused by something as simple as a buildup of hair, soap, or grease.

Foul Odors

A blockage in your pipes can cause foul odors from your drains. The smell could be caused by anything from rotting food stuck in your kitchen sink to organic matter caught in your bathroom’s waste pipe.

Strange Noises

A blocked drain can also be identified by gurgling sounds coming from your pipes. These sounds are often heard when water drains from toilets and sinks. They’re often caused by trapped air trying desperately to escape through the blockage.

Water backing up

If water backs up into other fixtures like toilets or sinks when you’re using appliances such as washing machines or dishwashers, it’s very likely that you have a blocked drain. Water backup can cause flooding if left untreated.

What To Do About A Blockage

Now that we’ve covered some of the signs of blocked drains let’s take a look at what you should do if you suspect there’s an issue with yours:

Use A Plunger To clear small blockages in your pipes, a plunger is a good choice.
Pour Boiling Water: Pouring boiling water down your drain can help break down soap scum and melt away any grease or fats.
Try A Store-Bought Drain Cleaner: Be careful when using these as some can damage pipes over time. You can also make your own drain cleaner with baking soda and vinegar.

If none of these solutions work, it’s time to call in a professional plumber. They’ll have the expertise and tools to find and remove any blockages from your pipes.

Conclusion

Blocked drains are frustrating and can cost you money. However, catching them early will help prevent future damage. You’ll quickly be able to identify the signs that we have discussed and take appropriate action.
