Flex-Drain 52011 Flexible/Expandable Landscaping Drain Pipe, Solid, 4-Inch by 50-Feet

It fit over the downspout and kept the rain water away from the house.

They are a little thin, but they work just fine. They’re easier to put away than the thicker heavier ones that’s for sure.

Installed a drain for runoff on a hill in the yard. Rented a trencher and got everything put in with no issues. I will say that this pipe is a bit less sturdy as it pulls apart to get to length. As the only load above this will be a mower,I don't expect any issues. If cars or trucks are involved you may want to consider a heavier pipe.

The good: The pipe was exactly as long as I needed it to be and saved me from trying to squeeze a 50ft full corrugated into my sedan at home depot. The bad: It didn't quite fit with the couplers I purchased, but I was able to get it to work with some modifications. Tip: To get the pipe fully extended, anchor one end (I pinned it in some cinder blocks) and work your way back from the anchor. Walk the full length a second time to be sure there aren't any stubborn spots (I had a few).

The product held such promise - an extension from my downspout to get water away from my foundation. I ordered both white and black versions of this. The white seems to be holding up for now, but the black has completely begun to disintegrate. On the one picture, you can see where the seam is coming apart. I didn't post photos of the other sections where it has just completely separated.

Have a couple of these that do a pretty good job just purchased another one but where the pieces are glued together got damaged I suppose in shipping but the Amazon box showed zero damage. This one leaks at that joint quite a bit. Unfortunately I didn’t keep the box for shipping so I guess I made a poor choice this time. Live and learn.

This flexible drain pipe goes far! I had plenty for two whelping pools (golden retrievers) and two drain ditches for their kennel. It was an awesome discovery!!!!

The fact that the 50ft pipe is actually two 25ft pipes glued together is a problem if the joint is damaged. On the pipe I got there was some crushing of the end of one pipe where it’s inserted into the other. A worker had used a ton of glue to try to compensate but it leaked a lot anyway. It ahouldn’t have been shipped in that condition. I didn’t notice the defect until I’d cut and fitted the pipe so I ended up throwing the whole thing away. When I was cutting it into pieces to dump it I saw many places where there were small holes in clusters at various points along the pipe. Not well made, carelessly jointed and too thin for you to be sure there are no punctures. Suggest you really check over carefully before you start fitting.
