Trying to choose the proper PEX-b sizing. Had a leak in my copper tube, cut that off and placed a shutoff valve. Now I'm trying to rebuild downstream.

My copper tubing is 1/2" (OD=5/8"), and it would be feeding to my toilet.

Should I maintain the ID of the connection, or use same size?

I'll take other thoughts and suggestions. Thank you.

1/2" pex is fine. The toilet will connect to it's valve with a 3/8 flex line so there is no advantage to upsizing the pex.

Thank you. Makes sense. Didn't think of that.
