Not true. There are certain things that can not be "disclaimered away." Product safety is one such thing. In other words, most such disclaimers discourage lawsuits, but realistically they aren't legally binding.

If you can pay for a good lawyer you can win against a disclaimer, other wise they work well. Thats why any company selling anything has one. It's the idea behind having a disclaimer, or else company's wouldn't pay for legal services like they do. That being said, back on topic.

Are Joel's cannons safe to use, (in a nutshell) is the question now?

I have talked with Joel several times in the last few months and I was under the impression that Joel machined all his fittings so there would not be any markings or other factory garbage on the fitting, in turn it gives the cannons a better look then a home built.

That really suprised me...I guess everyone trusted Joel so much back in the day that no one took a look at his launchers and called him out. Though, many of the pieces that he uses are NSF-pw or NSF-61.

And by the way, nice repair unisonmind; it looks clean.

Nice repair, I too am surprised at the DWV. It'd be interesting to see what Joel has to say.

DWV doesnt always mean unpressure-rated.
Though this is more often seen on metal pipe, a DWV, 200psi rated pipe, is fine to use.

DWV usually has a lower rating, but its not said that this always is the case.

Very true. I still see no pictures of this fitting that isn't pressure rated. I see a picture in this thread but there is no way you can read what it says.
