Dealing with a blocked drain can be frustrating, and it’s always best to catch the problem early. 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 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. This could be due to rotting food in your sink or organic matter in your bathroom’s drain.

Strange Noises

Gurgling noises coming from your pipes is another clear sign that you may have a blocked drain. These sounds are often heard when water drains from toilets and sinks. 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.

How to Deal with 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: 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. Alternatively, you can make your own homemade drain cleaner by mixing baking soda and vinegar.

If none of these solutions work it is time to call a professional plumber. They will have the necessary tools and expertise to locate and effectively remove any blockages in 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.
