None of the fittings or pipe are thin wall or cellular core. We won't have a problem with this gun. I look at it like this... I'd much rather an $8 endcap blow out than a fitting break and us be out of $200.
It is important to learn exactly what "schedule" means. It has nothing to do with the pressure rating. An SCH 40 part could be rated to 200 PSIG or it could be rated to 10 PSIG.
There is no pressure rating associated with SCH 40.
Cell core PVC is unrated for pressure but is still SCH 40.
All the schedule really means is that the pieces will fit together. All SCH 40 PVC pipe will fit into all SCH 40 PVC fittings. The pipe and fittings can come with different pressure ratings even for the same nominal dimension and type of part.
Pressure rated fittings and cell core "DWV only" fittings are both SCH 40. Only the pressure rated fittings are actually pressure rated (duh).
Sure looks to me like you've got several DWV only parts in the build.
