ProPEX expander fitting kit?
For RV plumbing, as far as I know, the "right" way to do PEX connections to have them last years to decades are not Sharkbite fittings where chlorine can attack the O-ring to cause leaks (there was a post on the Airstream forums about someone who tried using those, more than half of them leaked.)
I'm wondering if it might be worth it to buy a Uponor ProPEX fitting kit, with a Milwaukee Tool M18 cordless expansion tool. From what I've read, this is, hands down, the best way to do the job. It is expensive, but wood damage from a leak due to a bad fitting would more than pay for this tool and the fittings needed.
What other ways are reliable for plumbing, if repairs/upgrades are needed?
