You’ll need a putty knife, heavy-duty tape, water, and a large container such as a bucket.
Begin by removing the operating panel of the half vent window. To do this, open the window all the way. Take out the window sash by lifting up and pulling the bottom of the sash out first. Use a putty knife to remove the window track. If there are weep hole covers on your window, remove them at this time. Cover the weep holes with heavy duty tape. Fill the track with water until it’s filled half way up to the track edge. Let the water rest for at least fifteen minutes. If there’s no change in the water depth, there’s no defect in the windowsill or weep system. Drain the weep system by removing the tape and allowing the water to exit the system. Finish by replacing the weep covers, window track , and sash.
