I have the following question on aircon drain pipe :

Why a split aircon's indoor fan coil unit condensate will overflow when its drain pipe outlet is submerged in water during rainy and flooding days ? Condensate flow will resume to normal after flood water subsided and drain pipe outlet is above water level.

Thanks,

It needs to have a open tee/vacuum break where it exits the evaporator coil so the drain can siphon itself and drain naturally. Tip over a bottle of soda and it won't drain unless there is a hole at the top of it. When your drain pipe is submerged it prevents the natural siphoning effect from working.

Hey, lee swee hing!

Have you read the latest Chinese medical journal?

The title is "Chinese Rupture" by Dr. Who Kicky Dicky.
