Went to the hardware store and I was going to buy a sheet of copper but I didn't feel like spending 15 bucks on a sheet so I went to the plumbing section and found copper pipe caps. Looks just like a trail tech probe after some cutting and filling. I'm going to do some side by side testing later tonight with a trail tech.
I have less then 10bucks into the entire setup! Wow I hope this works.
I have a hardware store nonpetcock il be posting about when I get the parts in from china. It should be a lot better then the petcocks that eventually leak and it only cost like $3 bucks. (edited)
