A kitchen sink choke can quickly disrupt your daily routine. Water begins pooling in the sink, dirty dishes pile up, and every attempt to use the tap only makes the situation worse. Besides being inconvenient, a blocked sink can also lead to unpleasant odours and hygiene issues if left unresolved.
At PW Plumbing, we provide professional kitchen sink choke clearing services across Singapore for HDB flats, condominiums, and landed homes. Our experienced plumbers arrive promptly, identify the root cause of the blockage, and use the appropriate equipment to remove it completely. We focus on clearing the blockage thoroughly rather than simply pushing it further down the pipe, helping to prevent the same issue from recurring.
Different Types of Kitchen Sink Chokes and How We Handle Them
Not every kitchen sink choke is the same. The correct solution depends on the location of the blockage and what caused it. Below are the most common types of blockages we handle and how we restore proper drainage.
Trap Choke
Slow drainage often begins at the sink trap, where grease, soap residue, and food waste gradually accumulate. This is one of the most common blockages we encounter, and our team clears it efficiently to restore normal water flow.
How We Handle It:
- Open the trap and manually remove accumulated debris
- Flush the trap thoroughly with clean water
- Inspect the rubber seal and washer for wear
- Replace worn seals where necessary
- Reassemble the trap and test the drainage before completion
Grease Choke
Pouring cooking oil and grease down the sink may seem harmless, but as it cools, it hardens along the pipe walls. Over time, this restricts water flow and causes stubborn blockages.
Our plumbers remove grease build-up completely and restore smooth drainage while providing practical advice to help prevent future grease accumulation.
How We Handle It:
- Assess the extent of grease build-up
- Use hot water jetting to soften hardened grease
- Remove loosened grease from the pipe walls
- Inspect the remaining pipework for residual build-up
- Recommend preventive measures to reduce future grease blockages
Food Debris Choke
Food scraps, vegetable peels, and leftover waste can collect inside drainpipes. When combined with grease and soap residue, they form stubborn blockages that restrict water flow.
Our team removes these blockages completely and helps minimise the risk of future occurrences.
How We Handle It:
- Locate the exact position of the blockage
- Use a drain snake to break apart compacted debris
- Remove loosened waste from the pipe
- Flush the system thoroughly
- Recommend installing a sink strainer to reduce future build-up
Pipe Choke
Sometimes the blockage is located deeper within the drainage system, beyond the sink trap. These blockages are commonly caused by accumulated debris or foreign objects lodged further inside the pipe.
Our pipe choke experts use specialised equipment to locate and remove these blockages effectively.
How We Handle It:
- Inspect the pipe route to identify the blockage
- Feed a drain snake through the affected section
- Break apart and remove the obstruction
- Flush the entire pipe thoroughly
- Confirm smooth water flow throughout the system
Floor Trap Choke (Common in HDB Flats)
HDB kitchen drainage systems are interconnected with nearby fixtures. Even if your sink pipe is clear, a blocked floor trap can prevent water from draining properly.
Our plumbers quickly identify whether the blockage originates from the floor trap and restore normal drainage.
How We Handle It:
- Remove the floor trap cover for inspection
- Clear trapped debris and accumulated grime
- Inspect connections to the sink and surrounding fixtures
- Test drainage from all connected outlets
- Refit and reseal the floor trap cover securely
Shared Vertical Stack Choke (HDB Flats)
Many HDB flats share a common vertical drainage stack. When a blockage develops within this shared pipe, it can affect multiple units rather than a single household.
Our team identifies whether the issue originates from the shared drainage system and coordinates the necessary clearing work.
How We Handle It:
- Eliminate the possibility of a local sink blockage
- Check whether neighbouring units are experiencing similar issues
- Trace the blockage along the shared drainage stack
- Coordinate access for clearing work where required
- Verify that normal drainage has been fully restored

Common Causes of Kitchen Sink Choke
A blocked kitchen sink usually develops gradually. Some of the most common causes include:
- Cooking oil and grease that harden inside the pipes
- Food scraps, rice, and vegetable peels accumulating over time
- Soap and detergent residue combining with grease to form stubborn blockages
- Older or narrower drainage pipes in ageing HDB flats
- Shared floor traps collecting waste from multiple connected fixtures
What to Do Before Calling Us
If your kitchen sink choke occurs, stop using the sink immediately to prevent overflow. Clear the surrounding area so our plumber can access the sink easily, and make a note of when the blockage started or whether similar issues have occurred before, as this helps speed up diagnosis.
Avoid using harsh chemical drain cleaners, as they may damage your pipes and make the blockage more difficult to remove. Simply let us know what you’ve observed, keep the area accessible, and we’ll take care of the rest.
How do I know if my sink is blocked or just draining slowly?
Water that pools in the sink, slow drainage, gurgling sounds, or unpleasant odours usually indicate a developing blockage. The earlier it is addressed, the easier it is to clear.
Can I use a chemical drain cleaner before calling?
A mild cleaner may help with very minor clogs, but strong chemical cleaners can damage older pipes, particularly in HDB flats. If you have already used one, let our plumber know during the inspection.
How long does it take to clear a blocked sink?
Most kitchen sink choke clearing jobs are completed within an hour. More complex blockages located deeper within the drainage system or shared floor traps may take longer.
Why does my sink keep blocking even after cleaning?
Recurring blockages are often caused by grease build-up deeper inside the drainage pipe or issues within shared floor traps. Our plumbers identify and resolve the underlying cause rather than just treating the visible symptoms.
Do you charge extra for emergency or same-day service?
No. We provide transparent pricing before work begins, with no additional charges for same-day or emergency kitchen sink choke services.
