RE: Staybrite 8 Yes or No and why?
I say no, because really, what is is easier and quicker than 15/5? It’s easy to undo, easy fix leaks, easy to get creative with if you’re in a bind. The only time I have cooked a txv on installation is when I used sb8. (My fault. I used a wet rag as extra precaution and the water dripping on the joint messed with the flux.)
