What happens here

The video concludes by demonstrating the functionality of weep holes (or vents) located on the bottom sill of the window. These small openings are designed to allow any water that penetrates the window assembly to drain outwards. It is crucial never to caulk or clog these weep holes, as doing so would trap water within the window channel, potentially causing it to overflow and run back into the house, leading to significant water damage.

Goal: Ensure weep holes are clear to allow proper window drainage.

What they say

Hide

if you ever have any flashing failure, water will divert, hit the cap, and still run down the side of the window. As you see as water makes it into the window, it comes out these vents. If these vents get clogged or caulked, this water can fill the channel and flow back into your house. But when these vents are free, it allows this water to run out and empty your channel. Thanks for watching. >> Am I okay?
