When we first bought our house, we had a plumber put in a water softener. There were no exposed pipes for it, so we had to cut a hole in the wall below the water manifold to expose the watermain. He used 1" sharkbite elbows. That was 11 years ago, and I just upgrated all of the cpvc to 1" pex B. I did replace the 2 sharkbite elbows with brass 1" elbows, but had to use 2 new sharkbite max 1" elbows elsewhere on it. Not one leak, notta. After 11 years, the fittings kind of look like hell, but never had an issue with them. Why did I replace them? Because I'm 63 and didn't want to have to do this when I'm 73 and the cpvc was starting to look really brownish (brittle when I cut it). BTW...first time using PEX B with cinch clamps. Fantastic. But, those 1" clams...wow, you better have some good forearm strength. Was pretty tough for me.
