<human>: Condense the text into a few key points

Background: At my house, its just my mom, little sister, little brother, and myself during breaks from college.

So I am sitting in my basement, caveman status, when I head an odd noise coming from the boiler room. I open the door and there is water POURING in (it's currently a torrential downpour in northern NJ) from the wall. And not a hole in the wall, but the exhaust pipe from the heater for the house. This has never happened before; the sump pump normally takes care of all water seepage. So I begin freaking out, for fear the basement will flood. There is no reason for water to be coming in from there whatsoever, and its not like it hasn't poured here before. 

I start to think, and an idea comes to me. I had just raked a ton of old leaves off of the deck directly above this spot at ground-level. I go outside, and sure enough, the gutters above the deck are full of leaves/sticks and water is pouring out. Ordinarily, the leaves would have protected the basement from this cloggage, but my yardwork had opened the floodgates for water to flow down.
<bot>: I solved a domestic flooding problem by climbing on the roof in the middle of a thunderstorm unclogging gutters.
