Not sure what to do when water won’t drain? Whether it’s a slow-draining sink or a fully clogged tub, this common household issue can be a real nuisance. It disrupts your routine and, if ignored, may lead to more serious plumbing problems. Fortunately, many solutions can be tackled without calling in a plumber.
By understanding the causes and trying a few simple fixes, you can often resolve minor clogs yourself – saving time, money and stress.

Quick Fix – What to Do When Water Won’t Drain
- Use a plunger to dislodge minor clogs
- Try the baking soda + vinegar + boiling water method
- Pull out hair or debris with a drain snake or wire hanger
- Avoid harsh chemical cleaners unless recommended for your pipes
- Watch for signs of deeper problems, like water backing up in multiple drains
Understanding the Causes of Clogged Drains
Before trying any fix, it helps to understand what’s causing the blockage. Common culprits include:
- Hair in bathroom sinks and showers
- Grease from cooking, which hardens inside kitchen pipes
- Soap scum, a combination of soap and mineral deposits
Other habits can also lead to clogs:
- Rinsing coffee grounds or large food scraps down the sink
- Flushing non-biodegradable items like wipes or cotton buds down the toilet
To avoid future issues, adopt habits that prevent buildup – such as using sink strainers and regularly cleaning your drains.

What to Do When Water Won’t Drain – Easy DIY Solutions
Once you’ve identified a minor blockage, these DIY fixes often do the trick.
1. Plunger Method
Make sure there’s enough water in the sink or tub to cover the plunger’s rim. Place it over the drain and push up and down with even pressure. This creates suction to loosen the blockage.
2. Baking Soda and Vinegar Trick
Pour ½ cup of baking soda into the drain, followed by 1 cup of vinegar. Let it fizz for 30 minutes, then flush with boiling water. It’s a safe and effective solution for soap and grease clogs.
3. Drain Snake or Wire Hanger
Insert a drain snake (or a straightened wire hanger) to catch debris. Twist gently, pull out and rinse thoroughly. Avoid metal hangers in plastic piping.
Note: If your DIY efforts don’t work after a couple of tries – or if you notice water backing up – then STOP. Forcing it can damage your pipes.
Preventative Measures for Long-Term Drain Health
Once the water is flowing again, it’s smart to take steps to prevent future clogs:
- Flush boiling water weekly to clear early build-up
- Use baking soda and vinegar monthly as a natural maintenance treatment
- Install mesh strainers to catch food, hair and debris
- Educate your household: no oils, wipes or food scraps down the drains
Early warning signs include slow drainage, gurgling sounds or musty smells – all signs to act before things get worse.
Routine care is key, but you can also consider modernising your kitchen, for a cleaner, more functional space. Even small updates can help reduce mess, improve drainage, and simplify daily upkeep.

When to Call a Professional Plumber
If you’re facing:
- Recurring clogs
- Multiple slow drains throughout the house
- Sewage smells or water backing up
…it’s time to call a plumber. These issues may indicate more serious underlying problems, such as tree roots in pipes. This requires specialised tools and expertise to locate and resolve without damaging your system.
Before hiring a plumber, ask about:
- Their experience and credentials – always check reviews!
- Use of eco-friendly products
- Whether they offer upfront pricing or quotes
Natural and Eco-Friendly Alternatives for Drain Care
If you’re eco-conscious, great news – there are effective, natural options:
- Use enzyme-based drain cleaners instead of harsh chemicals
- Create your own mix with ¼ cup of salt, ½ cup baking soda, and 1 cup vinegar followed by boiling water
- Choose biodegradable products when buying off the shelf
These methods reduce pipe erosion, protect water systems and are gentle on the environment.
