Al, schedule 80 is designed (usually) for pressurized water supply installations, where schedule 40 is for D/WV (drain, waste, vent). 40 should be easily stout enough for pump out lines, but cost for that short line will be nothing for either. Just don't skimp on the pvc glue/cement - takes more than most think - especially as you get to 1.5" and up - and LOTS when gluing up 4" drain lines! (speaks the landlord)
Good luck with the install.
