Anyone know why sliding doors would have holes in the bottom runners. Main doors of building so be need to be there to let water out!!! Just now noticed with wild weather that water is actually blowing in!!! Will seal them up but wondering why they have holes??????

NO need to be there to let water out I mean ...

They be weep holes

They be weep holes

but what would weep out from a room inside!! only thing i see they can do is let water in when wet and windy like past few days??

i was half thinking they put all the doors in upside-down and the holes meant for ventilation!!! i dont see the point of them being there!! anyone?

I had 'sliding window holes' in a 13th storey newly constructed hotel room on the north central coast of Vietnam and then a typhoon came thru and the room got flooded..and they wanted to move me to another room but the view was spectacular and I refused to budge...

Yes, they indeed...be weep holes. There were none on any of my wonderful windows and I had to to around and drill some myself. If you ever get horizontal rain...and it is quite popular here, you would probably much rather have as much of it run outside as you would inside. Another nice little half assed thing they like to omit, its sealing the d*amn things. I had to go back and do that myself. Ahhh yessss....horizontal rain. ett

The holes in the patio door of my hotel room in Singapore lead to the outside.

Track installed the wrong way round perhaps?

If the weep holes are allowing driving rain in then install weep hole covers/caps

Yeah the covers look perfect for the upper ones which I see the point of as rain can get in the runner, but the bottom ones I see no point in??? I think will seal them up

That would be consistent with the Thai practice of putting the track for the screen doors inside the room, versus the western method (at least in the USA) of putting the screen doors on the track outside the room.

The sliding doors are on the outside rail...
