No, i am saying that the kind of pipe in the video is intended for FOUNDATION drainage. Do you even know what that is ? I am talking about house's wall's. I am also saying rigid pipe is a better choice for foundation drainage because of the potential for the rock used in foundation drain's to cause damage to flexible pipe.
You want 4 inch, flexible, perforated drain tile. It usually come's in 100' roll's. Use those word's exactly. Don't even say Schedule 40 PVC . That is wrong and will cause confusion.
