I am in the process of purchasing a home. It was built in October 2018. In February of this year, there was a pretty severe rain storm that dumped way more than the normal amount of rain in a short period of time. The home is built on a slope. The rain gutter system was overwhelmed it seems and there was some water intrusion at the foundation at one end of the house and rear door to the garage at the other end of the house which is built under the living space of the home and on the downward side of the slope.
Would there be any issue extending the square corrugated aluminum gutter pipe where it comes out from the roof at ground level to channel the water farther away from the house and farther down the slope to ensure the runoff isn't pouring out close to the foundation ? Maybe just 10-15 feet or so. It looks like Lowes has some flexible ABS product called Bend-A-Drain in a 4" x 25' length for about $26 that would do the trick.
I'm also thinking for esthetic reasons maybe trenching those sections of pipe and burying them a few inches underground and then when they exit have them pour out onto one of those splash blocks to diffuse the water stream somewhat.
