I started out as an MM in the Navy and this episode was right up my alley! Many days playing with industrial and residential "plumbing" and more than my fair share of playing with a torch ("no it isn't really on fire"...yet). 

PEX is awesome and it makes life a lot better and extra manifolds are a necessity if you plan on doing any substantial upgrades (bathroom) in the future. Thank you and I look forward to hearing more!
