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

If your sink or bathtub takes longer than normal to drain, you may have a blockage. This is the most obvious sign 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

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.
Use a store-bought Drain cleaner. These can cause damage to pipes over time. You can also make your own drain cleaner with baking soda and vinegar.

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

Conclusion

Blocked drains can be frustrating to deal with, but catching them early can save you money and prevent further damage. You’ll quickly be able to identify the signs that we have discussed and take appropriate action.
