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

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

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. 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.

How to Deal with 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 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. 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 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. You’ll quickly be able to identify the signs that we have discussed and take appropriate action.
