Prestantious 7ft Long Gutter Downspout Extensions, 3” Downspout Extender Drainage Pipe for 2"×3" Downspout and 3"×4"Downspout, Flexible Pipe Stretched Length 7ft, White,1-Pack

These hoses are a smaller diameter than what you find in the home improvement stores. Their construction is far superior, meaning they are much sturdier. The little connector was critical, I needed to make one long hose. Its smaller diameter and sturdiness meant I was able to bend it into a sharp U-turn and run the drainage along the side of the house. I ran a shallow circular saw cut along one side while the hoses were fully retracted, to invite water seepage along the way (Be VERY careful if you do this!) but find that once expanded the saw holes tended to curve somewhat and provide limited seepage there, which is okay after all because it is still a much better drain hose that I had.

I had a downspout that was dumping water about 2 feet from one of the window wells to the basement and would sometimes drip into the window well in heavy rain. This snapped right onto the end of the existing downspout without tools, and now even in a thunderstorm I don't see water dripping in the window well at all.

The larger 3"x4" fitting came pre-assembled to the flexible pipe. I needed to change to the smaller 2"x3" fitting, but encountered difficulty unscrewing the larger fitting. I finally resorted to spraying a bit of SILICONE LUBRICANT into the joint and that did the trick. I also gave a spray to the smaller fitting before screwing it onto the flexible pipe which made it easier. Instructions that come with the item should point this out as I read that others have had the same issue.

Works as it should and is doing great

Perfect
