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. This could be due to hair, soap, grease, or other simple causes.

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 noises are usually heard when water is draining from sinks or toilets. These noises are often caused by trapped air trying to escape from 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

We’ve already covered the signs of a blocked drain, but let’s now look at what to do if yours is causing problems.

Use A Plunger: A plunger can help dislodge any small blockages within your pipes.
Pour Boiling water: Pouring boiling hot water down the drain can break down soap scum, and help melt 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 will have the necessary tools and expertise to locate and effectively remove any blockages in your pipes.

Conclusion

Blocked drains can be frustrating to deal with, but catching them early can save you money and prevent further 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.
