Interesting you should say that, because the first night the rain got in, which was by far the worst of the two nights, the rain did only seem to be a drizzle, so at the time it didn't occur to me to be anything to do with wind. However, the second night it happened, I noticed that the rain was almost horizontal due to the wind at the time. So it might be nothing to do with wind. I'm also quite certain that the wind seemed to be a lot stronger on other nights when the bellows were fine and didn't leak at all, although I didn't make a note of the wind direction. I'm very open to the possibility that it's nothing to do with wind direction at all.There was no wind when my bellows leaked. Rain was moderate/heavy for an extended period of time. However, there’s no suggestion in the handbook that the bellows aren’t designed for that. It only mentions strong wind/driving rain, of which there was none.
Another possibility of the cause that I considered was the amount of saturation the bellows were subject to. The worse leak came on a night after two or three consecutive nights of almost constant rain. Maybe this is a factor?
