What PSI does PVC need to be?

I have two slow leaks I’m going to take care of this year. I’ll have to replace a short run of PVC piping, a couple 90degree turns and two screw-in connectors (one from filter out and the other screws into multi-switch in side (the thing that you switch between filter/backwash..exc).
Should I be able to get this stuff at Home Depot or Lowes?

Yep! Get Schedule 40. It's printed right on the pipe...sometimes as (sch. 40)
