Blocked drains are a common household nuisance—and they always seem to happen at the worst possible time. Whether it’s a sink that won’t empty, a toilet that won’t flush, or a foul smell creeping through your bathroom, a clogged drain can quickly turn into a stressful situation.
But here’s the good news: Not every blockage requires a plumber right away. With a few basic tools and a little DIY know-how, you might be able to fix it yourself. In this guide, we’ll cover:
- The telltale signs of a blocked drain
- Step-by-step methods to clear it yourself
- When it’s time to call a professional
- Tips to prevent future blockages
Signs You Have a Blocked Drain
Catching a blocked drain early can save you time, stress, and expensive repairs. Here are the most common warning signs:
- Bad odours: A sewer-like smell coming from your drains usually means there’s decaying debris—like food, hair, or soap buildup—stuck in your pipes.
- Slow drainage: If your sink or shower is draining sluggishly, it’s often due to a buildup of gunk restricting water flow.
- Gurgling sounds: Odd noises coming from your drains indicate trapped air caused by a partial blockage.
- Water pooling or backing up: Overflow or standing water around your drains suggests a blockage is stopping water from flowing properly.
DIY Methods to Clear a Blocked Drain
Before calling a plumber, try these five simple methods to clear the blockage yourself:
1. Boiling Water
Boil a full kettle and slowly pour it down the drain. This works best on grease or soap residue.
2. Baking Soda + Vinegar
Pour half a cup of baking soda followed by half a cup of vinegar into the drain. Cover it and let it fizz for about 15 minutes, then flush with hot water.
3. Plunger Power
Seal the drain with a plunger and pump firmly. The pressure may dislodge whatever’s stuck inside.
4. Check the U-Bend
Place a bucket under your sink’s U-bend, unscrew it carefully, and clear out any trapped debris.
5. Use a Drain Snake
A drain snake (or auger) can reach deeper blockages. Slowly feed it into the drain, twisting to break up or hook the clog.
When to Call a Professional Plumber
If DIY fixes aren’t solving the issue—or if multiple drains in your home are affected—it’s time to get the experts involved.
Professional plumbers use advanced tools like:
- CCTV drain cameras to locate hidden blockages
- High-powered drain snakes to reach deep into your pipes
- Hydro jetting to blast away tough clogs and tree roots
- Pipe relining or excavation for serious damage or collapsed pipes
Don’t let a small issue become a big one. If in doubt, contact the friendly team at Marco Plumbing for expert help.
How to Prevent Blocked Drains
While some clogs are unavoidable, many can be prevented with a few simple habits:
- Avoid pouring grease or oil down the kitchen sink. Let it cool and toss it in the bin instead.
- Use drain catchers in your bathroom to collect hair and soap residue.
- Only flush toilet paper—never wipes, sanitary products, or cotton balls.
- Keep outdoor drains clear of leaves, dirt, and debris.
- Don’t wash cat litter or coffee grounds down the sink—they expand and cause clogs.
- Check your plumbing regularly, especially if you live in an area with tree roots or hard water.
