PEX is flexible, corrosion-resistant, and significantly cheaper than copper. But the decision of which PEX type to use, which fitting system to choose, and when to use push-fit vs crimp vs expansion connections is something most tutorials handle badly. This episode covers everything you need to know before you cut a single pipe: PEX-A vs B vs C and why it matters, the expansion vs crimp vs clamp tool decision, the copper-to-PEX transition points where most failures happen, how to pressure-test your own work before closing walls, and the clear line between what you can handle yourself and what requires a licensed plumber.
