I have found what I think is a big difference in the crimp vs press pex. All the Zurn I have done when the copper ring is crimped the pex still rotates on the fitting. The Viega Press (with my ridgid 100b pressing tool) are tight no movement unless really forced. This makes you have to get everything how it needs to be the first time but thats how always was with copper anyway. And I have no scientific proof but sturdy non moving seems like a better connection.
No announcement yet.
