I need a 10-ft length of corrugated drain pipe (4-in diameter, typ. nominal). Both Lowes and Home Depot sell (a) a 10-ft length of “corrugated solid pipe” and 10-ft length of “corrugated perforated pipe” that sounds like what I need. But! Both have similar if not identical descriptions (where more details are provided).
Which do I want? I simply want a corrugated drain pipe with some flexibility to run rain water from the downspout away from the house. “Solid pipe” sounds rigid and “perforated” sounds like it full of holes, like a soaker hose*, maybe? Please advise. Thanks!
*Note: I am aware there is a roll-up, plastic material you can attach to the downspout that will unfurl when it rains, and this roll-up plastic material can be said to be perforated to act as a soaker hose. But, i strongly believe what I described above, based on the pictures on the respective retailers’ websites, do not appear to be referring to this style of downspout extension…
should not be referring to
