Agree, except use vise grips or another set of pliers to hold the spigot so the internal pipe sweat connection or glued PCV don’t get broken. I also center punch the break off screw stud, it easier just drilling the soft metal screw than housing. Plus have to be carefully not to drill into the spigot threads.
When I install new on I don’t tighten the lock screw so tight that it breaks off as designed
