I'm not going to argue with you if you're happy.

I'm also not going to argue with guys that have been in business for 40 years currently installing 2-4 million feet per year per machine, and who have to stand behind the work.

Drainage is a very mature industry here in the Great Lakes basin, and the contractors thinned out to the varsity squad, still booked out 12-36 months.

The 3" I have, I am happy with, but was laid to the parameters I shared. Perhaps if there was the odd band of fine sand that your tile traversed, or you clip the odd stone, you may have had a different outcome. I respect your observation, but I'm going to probably follow the advice of the locals.

Keep putting the pipe to it...
