Hi,
I have a UPVC Window where the water pools in the window frame channel (as per the below photo). As the height of the "side wall" of the channel is lower on the inside, the water comes into the house. As you can see there are three drainage holes (and another three on the other side). None of these holes are blocked. This window has been in place for 10 years, but only recently started leaking!....
On the outside of the window, there are three concealed drainage holes on the underside of the frame, located where I have marked the three black lines (below photo). None of these holes are blocked.
There are also drainage holes in the bottom of the window section that opens. These holes empty into the channel, but it is not clear whether the water is bypassing the seal against the glass in the below photo) OR the seal between the section of frame that opens against the window frame when it is closed.....
From prodding around with a metal coat hangar, it seems might be two "chambers" and that they are not connected. I think there is a top "chamber" that the 3 holes drain into from the channel in the window frame, but can find no way that the water can then find its way into the bottom "chamber" which hosts the 3 concealed drainage holes on the underside of the frame that would release the water onto the external window seal.
I can't drill straight down to open the potential bottom chamber to the top chamber due to the angle.
All I can think of doing is drilling the existing top drainage holes in the window frame channel, so that they go straight through to the outside. They won't then be concealed on the outside but that's not a problem.
Any ideas would be much appreciated. I don't know what the cross section would look like for this type of frame, if I did it might help decide a course of action. I also can't understand why the water is not draining to the outside.
Thanks
