So what is this Green Cover? It BLEW off, (never did that before!) in last nights thunder/hail storms.
Question is what is the black pipe lead to and can water get down it and into the garage from the crawl space? When we get extremely heavy rains / extreme downpours, (not just heavy rain - no issues), we get water coming into the garage from the crawl space and I am wondering if the water is running down this pipe and into the crawl space???
perhaps it got banged by some large hail which "tipped" it off. Is this the same corner you have has trouble with the overflowing gutters?
If this is the corner that floods this may have been put in to drain the water away ...»
look around on your property for an exit pipe...then have a helper shout into this hole...it they are connected your should be able to hear them more clearly.
