How to make the best union.

[rsgpit]

I made a small union, but you have put the burst disk between the threads of the piping. Is this right?, or is there a better way to make a union.

Also, would a spring loaded mechanism that pops the burst disk work?

You need to go to Home Depot and take a short tour of there PVC fitting section. I dont follow you on the spring operated mechanism that pops your burst disk. Please explain a little more.

Right after the union, im gonna bond a hinge to the inside of the barrel, and attatch a bolt or nail to the hinge, and then attatch a spring to the hinge, and i'll drill a small hole in the barrel, and attatch some cable to it, and you pull it back and let go, and it pops the union.
