How to Clear a Drain Choke in Singapore — DIY vs Professional Plumber

A drain choke is one of the most common plumbing problems in Singapore homes. Here is how to handle it yourself — and when it is time to call AOT.

Step 1: Try a Plunger First

For minor chokes in the kitchen sink or bathroom floor trap, a plunger can dislodge the blockage. Use a cup plunger for sinks and a flange plunger for toilets. Plunge firmly 10–15 times.

Step 2: Use a Drain Snake

A hand drain snake can reach deeper blockages in the U-trap. Insert and rotate to break up or pull out the obstruction.

Step 3: Chemical Drain Cleaner

For grease build-up in kitchen sinks, pour 250ml of alkaline drain cleaner, wait 30 minutes, then flush with hot water.

When to Call a Professional Plumber

• All drains in the house are slow → Main drain blockage
• Water backs up into the toilet when you shower → Serious choke
• DIY methods failed twice → Need hydro-jetting
• Sewage smell → Possible sewer line issue
