Why would you roll schedule 80? I mean if your using schedule 80 I would thread it and use the heavy walled fittings. Maybe someone here's used vics with schedule 80 before but I'd be interested to see if the vic couplings and elbows are rated for that level of pressure. Vics on schedule 80 seems a little asinine to me.
Buffalo, not everyone here is union. I'm not. But I definitely agree, the piping is our work regardless.
