Confused about Pex tubing and cpvc

I am refurbishing a rental house. It is plumbed incoming water with pex tubing. I would like to know if I can marry this to cpvc with a cpvc connector or a pex tubing plastic crimper connector. I cannot afford the $100 for a multi size crimper as the pex is of different sizes. So, does anyone know the answer and method to do this??????

Thanks,
Stacey
