R-
Don't be too hasty to make permanent changes.
Of course I cannot see your installation from here but I doubt that
the elbow alone is all (or even most of the problem)
Any chance of a picture?
I'd put my money on the 40' horizontal run. I mentioned this
earlier but I think it got missed......how much elevation change does
the drain line have over the 40 feet? It needs about 10"......5"
could work but without sufficient, drop the water won't move very
well.
You say the down spout is anchored "way down low" does the land fall
on the way to the lawn?
cheers
