I wonder why they thought "PVC" wasn't sufficient and had to spell it out "rigid polyvinyl conduit"??? Seems to keep getting more complicated to me instead of simpler:( Plus they're using more ink:) Steve...

Steve: Are you referring to whats printed on the side of a stick of conduit? The only reason I could see them printing out " Rigid Polyvinyl-Chloride" is so there is no ifs and or butts about what it is.. Ya never know someone may try to sub "CPVC" for "PVC"..

Schedule 40 Rigid PVC I notice says for underground and above ground use. Are they still making Schedule 80? I cant seem to find schedule 80 PVC around here.

They should have Sch 80 at the supply house but it isn't going to be at Home Depot

Thanks. The one supply house did not have it either around here. Will check another.

"SCH 80" is another one of those "I can't describe subject to physical damage but I know it when I see it" things. If the AHJ thinks things are subject to damage, suppliers will stock Sch 80.
It usually gets used for a PVC riser coming out of the dirt here. Commercial and certainly any service conductor raceway. Not so much for a 1&2 family outlet out in the garden.
