I have a 4 inch pvc vent pipe that goes from the basement , through the attic and out the roof. Sticks up about 3 feet. When the wind blows it vibrates or sings. I can hear it vibrate in the bathroom and feel it in the basement. What can be done to stop this? The top is cut off square. Maybe cut it at a 45? or cut a notch in it?
