Well, I went to the "tutorial" and then asked DH (landscape designer and 
irrigation specialist) about it because it didn't sound right.

You do NOT want to use Class 200, or Class anything.  It is known in the 
industry as "eggshell."  Lot of sunlight, using a saw without holding your 
mouth the right way, if buried, someone or something (critters) walking on 
top of it and it will crack.  It doesn't last, it won't take pressure.

Around any of the bigger valves (3" and up), use a Schedule 80.  The rattle 
from the bigger valves when they turn on (they shake, hard!) will crack the 
Schedule 40 over time and sometimes over very little time.
