A choked drain almost never happens overnight. Grease, hair and food scraps build up inside the pipe for weeks until the water finally backs up — usually at the worst possible time. The good news is that most chokes in Singapore homes are easy to prevent. Here is how to keep your drains flowing.
Keep grease and oil out of the sink
Hot cooking oil pours away easily, then cools and hardens inside the pipe, trapping food bits and forming a stubborn plug. Let used oil cool, pour it into a sealed container and throw it in the bin. Wipe greasy pans with a paper towel before washing.
Use a strainer over every drain
A cheap basket strainer in the kitchen sink and a hair trap over the bathroom floor trap catch the things that cause most chokes — rice, coffee grounds, vegetable peel and hair. Empty them into the bin, not back down the drain.
Flush drains with hot water weekly
Once a week, run hot water down the kitchen sink for a minute to melt away light grease before it sets. For a natural clean, pour in a little baking soda followed by hot water. Avoid relying on harsh chemical drain cleaners — they can damage older pipes and rarely clear a full blockage.
Watch what goes into the toilet
Only the obvious belongs in a toilet. Wet wipes — even those labelled flushable — kitchen towel, cotton pads and sanitary products do not break down and are a common cause of serious chokes and overflows.
Act on the early warning signs
A drain rarely chokes without warning. Call a plumber early if you notice any of these:
- Water draining slower than usual at the sink, shower or floor trap
- A gurgling sound from the drain after the water runs
- A lingering bad smell rising from the floor trap
- Water pooling around the floor trap when you shower
If a drain is already choked, a professional clearing removes the blockage at the source and protects your pipes — far safer than forcing chemicals or a wire down the line. Catch it early and a quick visit saves you from a messy, costly overflow later.
