Hvac
 
I have the following question on aircon drain pipe :

:huh: 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.
