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

Blockages can occur when your bathtub or sink drains slower than usual. 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

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

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. 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. 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 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.
