Water Won't Drain in Your Singapore Condo? Here's Whose Problem It Actually Is

Whose Problem Is It, Really?

When water backs up in your home, the first question is always: is this my pipe or the building's?

Here's how it works in Singapore condos:

• Your responsibility — everything from your unit's individual pipes, floor traps, and basin outlets
• MCST's responsibility — the main stacks and common pipes that serve the entire building

The tricky part? Both can cause the exact same symptom — water backing up. And MCST will almost always say it's your pipe first.

In most cases they're right. Blockages typically originate from within the unit — accumulated grease, hair, debris, or foreign objects stuck in your floor trap or basin outlet.

But the signs are easy to miss until it's too late:

• Slow drains — water takes longer than usual to clear from your basin or shower
• Gurgling sounds — air trapped in blocked pipes forcing its way through
• Water backing up — the most obvious sign, and by this point already a problem
• Foul smell — stagnant water sitting in a partial blockage, especially in floor traps
• Wet patches on walls or ceilings — water finding its way through gaps you can't see
• Damp flooring — moisture seeping up from below, often a sign of a deeper pipe leak

Each one of these is a warning. Ignore the first, and you'll eventually meet the last.

But here's what catches homeowners off guard: even if the blockage is in the common pipe, you still need to prove it. That means calling a licensed plumber to inspect, document, and report — before MCST will even send someone to investigate.

Bottom line: don't assume. Don't wait. The longer water sits where it shouldn't, the more damage quietly builds up behind your walls and under your floors.
