The Dangers of Neglecting a Blocked Drain and What You Should Do

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. 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. 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. 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 water down your drain can help break down soap scum and melt away 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’s time to call in 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. 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.
