Greg,
Yes he is clueless and has me running around like a blind dog in a meat house looking this crap up!

Sch 40 and Sch 80 is all there is besides UTILITY grade PVC that is THINNER than sch 40 and 80!!

I told them install it and have 3" coverage of concrete all around and dye the concrete red and use metal warning tape within 12" of finished grade...

thanks Greg

regards

Greg
