Blocked drains are a common household problem that can lead to unpleasant odours, slow-draining water, and even water damage if left untreated. In this comprehensive guide, we will cover the common causes of blocked drains, how to troubleshoot and clear them, and tips for preventing future blockages. With the right knowledge and tools, you can save time, money, and frustration by tackling this issue yourself.
1. Common Causes of Blocked Drains
There are several reasons why drains become blocked. Some of the most common causes include:
– Hair and soap scum build-up: Hair and soap scum are notorious for causing blockages in bathroom drains, particularly in shower and bathtub drains.
– Grease and food debris: Kitchen sinks often become clogged due to grease, oil, and food particles that accumulate over time.
– Foreign objects: Items such as toys, sanitary products, or other debris can accidentally end up in drains, leading to blockages.
– Tree roots: Tree roots can grow into underground pipes, causing cracks and blockages in sewer lines.
– Mineral build-up: In areas with hard water, mineral deposits can accumulate inside pipes, leading to reduced water flow and blockages.
2. Signs of a Blocked Drain
If you suspect you have a blocked drain, look for the following warning signs:
– Slow-draining water: If water takes longer than usual to drain from your sink, bathtub, or shower, it could be due to a blockage.
– Unpleasant odours: A foul smell coming from your drains may indicate a blockage, especially if it’s accompanied by slow draining water.
– Gurgling noises: If you hear gurgling sounds coming from your drains, it could be a sign of trapped air caused by a blockage.
– Water backing up: When water starts to back up out of your drains, it’s a clear indication of a blockage.
3. Troubleshooting and Clearing Blocked Drains
Once you’ve identified a blocked drain, there are several methods you can use to troubleshoot and clear the blockage.
- DIY Drain Unblocking Methods
Before calling a professional, try these DIY methods to clear your blocked drain:
– Plunger: A plunger can be used to create suction and dislodge blockages in sinks, bathtubs, and toilets. Make sure you have a tight seal around the drain and use a back-and-forth motion to create suction.
– Drain snake or auger: A drain snake or auger is a flexible, long tool that can be inserted into the drain to break up and remove blockages.
– Baking soda and vinegar: Pour one cup of baking soda down the drain, followed by one cup of white vinegar. Let the mixture sit for at least 15 minutes before flushing with hot water. This method can help break down grease and soap scum.
– Chemical drain cleaners: While chemical drain cleaners can be effective at clearing blockages, they should be used with caution, as they can damage pipes and harm the environment.
- When to Call a Professional
If your DIY efforts don’t resolve the blockage, or if you’re dealing with a more serious issue like tree roots or damaged pipes, it’s time to call a professional plumber. They have the tools and expertise to quickly and safely clear your blocked drains and address any underlying issues.
4. Preventing Blocked Drains
To prevent future blockages, follow these tips:
– Use drain covers: Place mesh drain covers over your sink, shower, and bathtub drains to catch hair and debris.
– Dispose of grease properly: Instead of pouring grease down the sink, let it cool and solidify, then dispose of it in the trash.
– Be mindful of what goes down the drain: Avoid flushing items like sanitary products, wet wipes, and food debris down your drains.
– Regularly clean your drains: Use a mixture of baking soda and vinegar or a drain cleaning brush to regularly clean your drains and prevent build-up.
