Aircon Drain Pipe Keeps Clogging? Here’s Why It Happens

Noticing your aircon leaking water or dripping frequently?
In many cases, the issue is not the unit itself, but a clogged drain pipe.
This is a very common problem in Singapore, especially due to humidity and dust buildup.

Common Reasons Drain Pipes Get Clogged
Dirt and dust buildup over time
Algae or mould growth inside the pipe
Improper installation or poor pipe slope
Lack of regular servicing
Debris stuck in the drainage system
Why This Happens So Often in Singapore
Singapore’s humid climate creates the perfect environment for moisture buildup.
When moisture combines with dust inside the drainage system, it forms sludge, which can easily block the pipe.
Without regular cleaning, this buildup becomes worse over time, leading to frequent clogs and water leakage.
