    You would not want to do that as leaves, etc. would clog any mesh up.

      Not correct length as advertised.

        Bad quality
        Came broke. Noticed many holes while installing it

          Trash. Worse pipe I have ever used. Bring back ADS or NDS products.
          I should have read more reviews before putchasing 500' of Amerimax garbage pipe. What was so bad about ada or nds 4" corrugated pipe? I think it comes down to shipping. This accordian trash is cheaper to ship. I will not be buying this again. It collapses under very little weight. Two welded 25' pieces with two 25' socks are a real pain to install. I hope whomever makes this is embarrassed. I doubt it though. They are probably laughing at us suckers for buying it.

            Leaking, poor quality.
            I purchased 4"x50'. It's actually 2 25' sections. Not a problem for my application, however one section had a crack and leaking. I wish I'd test it prior spending time installing it.

              Split in two after one month
              I bought this 25 ft drain pipe a month ago we've had two light rains. Checked it today as we have rain coming and it's completely split into two pieces.

                Not 50 continuous feet BUT (2) 25` pushed together
                I had this shipped to me an was happy to get it before the winter rains but i noticed it was NOT the full 50 feet like advertised but (2) 25 feet pushed together so i had to search for a short screw to hold them together in a gusty breeze. The modification wasn`t done deceptively by a worker at the store because it was loose but where it was manufactured because it had the plastic wrap band still around it. Id bought these before and maybe got 2 years use out of it but the ones i have been buying recently im lucky if they last a year because they deteriorate fast and fall apart. I kept it because it would have been a pain to drive it to the store and then search around elsewhere to have it shipped to me again. I am not happy that i was deceived and that these do not last a decent amount of time, I would recommend trying to find something stronger if you want longevity

                  This was perfect for what I needed. It has held up well so far. I was surprised how large it expanded when i took it out. i thought it was going to be smaller. High quality. Would purchase again

                  Absolute garbage and thin and size doesn’t match the rest of the products sold at Home Depot
                  I ordered this for pickup to finish an installation for products that I had ordered from Home Depot. I had exclusively ordered everything previously from Home Depot. This product was smaller and thinner than the rest of the product I ordered. It’s horrible. How can Home Depot carry 4” drain pipe that is not of the size and quality of the other 4” drain pipe that they carry? I was in a situation where I had to use the poor quality pipe. I’m not happy. Thin, lightweight, pitiful

                    Good temporary extension
                    Worked really well as a temporary extension to my sump pump drain, to move water over to the driveway and down to the storm drain. Used during a recent flooding rain event. Easy to bend and the 25 ft. length was just right. Not sure I would use on a permanent basis, as it is fairly thin material. I fastened to the sump pump drain with a small sheet metal screw. See accompanying photo.
