Pvc/cpvc determining difference?

I need to tee into the 3/4" main water line,plastic pipe coming into the house that is buried underground, after the meter of course.

I do not see any markings on it? So how would I know if it is PVC or CPVC? This is in SW FL, the house is 25 years old but was originally on well and later changed to city water, so I do not know how old pipe is.

If I cannot tell the difference what would be the best type of T to use? JIm

Typically this would be PVC.

Measure the OD of the pipe. Go fo a home center and compare to the OD of PVC and CPVC. Hint, they are different, PVC is

Probably difficult to tell with pipe that's been underground, but PVC and CPVC are slightly different colors.

If its the original line from the home its PVC, 25 years back CPVC was not common in south Florida, anyway pvc white cpvc bone beige type color.

Thanks for the responses! Much ado about nothing though. What I thought was dirt streaks was actually printing, it is PVC. 2nd mistake I made in this century. Thanks again. JIm
