A blocked drain can cause frustration and should be addressed immediately. We have compiled a list with signs to watch for when you are dealing with 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

Foul odors coming from drains can indicate that there’s a blockage somewhere in your pipes. This could be due to rotting food in your sink or organic matter in your bathroom’s drain.

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

A blocked drain is when water backs up in other fixtures, such as sinks or toilets, or when you use appliances like washing machines or dishwashers. If left untreated, water backup can lead to further issues such as flooding.

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. Alternatively, you can make your own homemade drain cleaner by mixing 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. By keeping an eye out for the signs we’ve discussed above, you’ll be able to quickly identify when you need to take action.
