Dual Wall Corrugated Pipe for Underground Drainage System for Roof Run Off

http://www.frenchdrainman.com We're running a downspout, an apartment building. We're using a dual wall corrugated pipe. It's smooth on the inside and corrugated on the outside. Very flexible, but yet rigid, strong. All right, let's go through the system so I can explain why we use the dual wall. You can see by the big trees in this neighborhood, they have a lot of leaves. There's a long gutter troughed on this building and it's impossible to get up on a ladder and keep these gutters clean.  So I know that these downspouts going to see leaves. There's going to be leaves coming through this downspout. Now I'm not going to bore you with the math, but I've already did the calculations and when the water falls at the height that this downspout happens to be, by the time we get into the underground system, we're going to pick up a lot of velocity and we're actually going to have, and again I'm not getting into the math, I'm not here to bore you with that, but we're going to have nine PSI pounds per square inch. That is fantastic. That's going to be great. Now, this was the long run and we're taking it away from the building. We're using 2, 20-foot pieces of dual wall pipe and we're taking that to a six-inch NDS catch basin so we can clean those leaves out the dual wall. The smooth inner wall is going to let the leaves run through this pipe. It's like a slip and slide. It's just like a luge. So all the leaves are gonna basically come down this pipe into this NDS catch basin. So the maintenance is literally to just take the lid off, clean the leaves out of the bottom. And that is it. It's that simple.  In truth though on a good hard rain, it'll blow that lid off and any shingle grab on leaves in the basin. We'll just end up in a line about the only real maintenance here is putting that lid back on after a hard rain. [...] Read More: https://www.frenchdrainman.com/dual-w...
