Customer Reviews for Amerimax Home Products FLEX Drain 4 in. x 8 ft. Black Copolymer Solid Drain Pipe

This flex pipe is easy to install, durable a nd greatly priced

This is very thin pipe, easily deformed. I don’t feel confident about its longevity. It was painful to extend to its full length—every time I tried to pull it out, it caused it to deform in places, and I couldn’t always correct that, so some of it just looks awful and dented. They make a ‘pro’ grade product sold in stores, but it was too long for my purposes; that was made of a better heavy grade plastic. This one was online only, and each unit I have stretched out to length has deformed unacceptably—I was worried it would split where the black plastic turned white. So far it hasn’t, but it has been only a few days. I’m not using this stuff anywhere that would be a disaster if it leaked, at least. This is not a pipe strong enough to bury, just to leave above ground as an extension off a downspout. They make a really sturdy though annoying flat version to bury, and if you’re doing a French drain, use the pro version—this one can’t handle gravel over the top or any kind of weight without collapsing. I guess this explains the very ‘reasonable’ pricing!!!

Product leaks, the seam is not well welded.

Attached to roof gutter downspout during atmospheric river rainstorm in CA to remove water flooding away from house

Lightweight, easy to carry. Nice and flexible. I wouldn't put it under a driveway, or too close to the surface in my grass. I would definitely use it again.

Well made. Hoping it lasts in the Florida heat and sun. I’m using it for drainage. Connected to downspout.

Arrived in a timely manner and works well. Thank you.

it is good product very easy to clean. wish you had a bigger pice like 4x 9 0r 10'

Very thin plastic. Does not last more than one season, if it makes it through the season. Seams easily split and leaks. Sides crush in easily when trying to expand. The one I just received was leaking with a split seam on first use after receiving it. Now have to hassle with a return and trying to compact the 50 ft back to shipping size. Home Depot sells solid drain pipe that is not expandable and collapseable. But is much thicker and sturdier than this flimsy pipe. Save yourself, don't buy it.

Thinner material than previous

Bought as solid drain pipe, but it developed Pinpoint Holes after short period of time

this fit on my downspout adaptor just fine and then onto my existing drain p[ipe EXCEPT this seems to have more holes / leaks than solid places. Likely won't buy this again, now that it stretched out it is 25' long and too much trouble to return it.

It works as expected.

After a few winters this Amerimax drain pipe became brittle and cracked. I had to remove then replace it all over again. I don’t recommend any of Amerimax’s cheap products 🥴😰😡🤬
