Hey Todd...thanks for the props.
The fabric is a roll of 3' wide landscape fabric (big box store) with a 25 year rating.
The perf pipe is generic, too. 4" dia bell end that glues with PVC glue. There are two continuous rows of holes in each pipe. Each of the 2 rows are nearly opposite each other along the length of the pipe. On the sides of the house that carry the gutter feeds, we set the pipes so the holes are at each side....creates a gutter at the bottom of the pipe to carry the larger amounts of water. At the ends of the house where the pipes don't see the gutter flow, we set one row of holes about 4 or 5 o'clock to allow seepage to flow in a bit quicker and lower within the lined trench. The 2 corners of the house that are opposite the exit drains are simply connected with 90 degree elbows. The 2 corners that also continue out into the yard are Tee's.
