I am getting ready to re-pipe my home. I am going to tackle a great deal of it myself. I am leaning toward Zurn PEX for a few reason over PEX A. The appeal of Zurn is it can be expanded as well. The issue I have is I find very few references of people that did Zurn and expansion vs. clamp/cinch. Expansion would surely be easier and I would by the Milwaukee M12 tool if I go the expansion route or the Ryobi Power PEX Clamp cinch tool. Curios if there are people that have done Zurn expansion and care to share their experiences. If I do expansion I will not upsize the piping, but if I do clamp/cinch then I will be upsizing the pipes. The biggest pro I can see to clamps is I can use the Boshart Stainless fitting which have curved elbows to help reduce resistance and turbulence.
