sink / basin blockage cleaning service
At All Plumbing.SG, we take the hassle out of plumbing problems. Here’s how we handle sink or basin choke cases professionally and efficiently:
1. In-Depth Assessment
We begin by assessing the sink or basin and pipework to locate the exact cause and severity of the choke. This may involve visual inspection, probing, or drain camera usage.
2. Advanced Tools & Techniques
We use high-grade plumbing tools such as:
🔹 High-pressure water jetting
🔹 Manual and mechanical drain snakes
🔹 Suction pumps
🔹 Pipe descalers
These tools allow us to remove clogs effectively without causing damage to your plumbing system.
3. Thorough Cleaning
After clearing the blockage, we flush and clean the pipes to ensure smooth water flow. We also deodorise the drain to remove any foul smell caused by the choke.
4. Preventive Advice
Once the job is complete, we share expert maintenance tips to help you avoid future chokes. If needed, we can also recommend upgrades to your basin fittings or drainage design for long-term efficiency.
Types of Sinks / basins We Unclog
We provide full service across different sink types and installations:
🔹 Kitchen Sinks
Often clogged with grease, oil, and food particles. We specialise in HDB kitchen sinks and island sink setups.
🔹 Bathroom Sinks
Hair, toothpaste, and soap scum are common culprits. We clean out the P-trap and main lines efficiently.
🔹 Utility and Laundry Sinks
Used for cleaning and maintenance—these sinks often collect debris and need thorough flushing.
🔹 Commercial Sinks
We serve cafes, restaurants, and commercial kitchens where daily use can cause frequent chokes.
DIY methods for clearing sink / basin blockages
Before calling a plumber, you can try some simple DIY methods to clear minor chokes:
1. Use a Plunger
A standard cup plunger can often dislodge soft clogs. Make sure there’s water in the sink or basin to cover the plunger base, then plunge up and down firmly.
2. Boiling Water
Pour boiling water into the sink drain slowly in stages. This helps dissolve grease or soap buildup.
3. Baking Soda & Vinegar
Pour ½ cup of baking soda, then 1 cup of vinegar into the drain. Cover the opening and let it sit for 20–30 minutes before flushing with hot water.
4. Manual Trap Cleaning
If you’re handy with tools, you can remove the P-trap (U-shaped pipe) under the sink to clean it out manually. Keep a bucket underneath to catch dirty water.
⚠️ If these methods don’t work, or the sink keeps choking again, it’s best to contact a licensed plumber to investigate deeper drainage issues.
preventing future sink / basin blockages
Prevention is always better than cure. Follow these maintenance tips to keep your sink or basin drains clear and functional:
🔹 Use a Drain Cover or Strainer
Install a small mesh strainer over the drain to catch hair, food particles, or debris before they enter the pipe.
🔹 Dispose of Waste Properly
Avoid washing food grease, tissue, coffee grounds, and thick substances down the drain.
🔹 Flush With Hot Water Weekly
Pouring hot water down your basin drain once a week helps break down oils and buildup before they cause a problem.
🔹 Clean the P-Trap Regularly
The P-trap (U-shaped pipe under the basin) can collect gunk. Have it cleaned out periodically, or learn how to unscrew and clean it safely.
🔹 Be Mindful of What You Flush
Only water, diluted soap, and safe cleaners should go down your basin. Anything else may cause damage or blockage over time.

Blockages are usually caused by hair, soap residue, grease, food particles, small objects, or mineral buildup that get trapped in the pipes or floor traps. Over time, these materials restrict water flow and cause slow drainage.
Avoid flushing hair, food scraps, grease, or non-degradable items down the drain. Regularly clean the trap and use strainers to catch debris. Scheduling periodic plumbing maintenance can also prevent clogs.
