I am using 1 1/4 schedule 80 conduit to go across my driveway from my shop to garage and at the supply house they said to use the schedule 40 90's. They said nobody uses the schedule 80 90's plus they don't stock any. Where the 90's are is not going to be driven over. Is it acceptable?

We use sched 40 exclusivly. There is no way that driving over buried conduit could come close to harming it. Sched 80 is overkill.

We also never use 1 1/4.

1 1/2 or 2" is about the same money and WAY easier to pull thru.
