CPVC diameter conundrum...

in THE MAIN WALL
when to replace a water heater last week in a Mfg. home... I went to hook into the existing cpvc line w/ a SS water heater connector and the sharkbite fitting would not go on easy at all. In fact it would not even take a std. 3/4" cpvc fitting either. Piping appears to be 3/4" Flowgard gold, sdr 11... normal stuff. But it has a slightly larger diameter that will not get inside a fitting. I ended up making it "work" by using a 3/4" Sea-tek coupling that I shaved part of the inside out and jammed it on w/ everything I had. I am not comfortable leaving it that way for long.... any thoughts? I do not think it froze as CPVC has little resistance to freezing. ty,kpc

    another thing....

    I did notice when cutting into the tubing w/ the cpvc cutter it was VERY brittle. It did not cut clean. I ended up having to use a pull saw to get a square edge.

    pvc dia.

    Not schedule 40 ? Not CTS - copper tubing size?  Was it quest or cresline tubing? polyethelyne. Was it connected with copper crimp band type connectors?
