Brass, SS, or PVC Pressure Tank Plumbing?

Can anyone tell by my pictures?

What is the OD? If you don't have a caliper, what is the circumference?

Is that shiny part a check valve? Sorry to see that.

3/4 CPVC is 0.875 OD, and poly pipe for wells is about 1 inch plus or minus, depending on the wall thickness (and psi rating). The inside diameter of SIDR ASTM D2239 3/4 is fixed at 0.824 so they all use same barb size.

I don't have a caliper but will this picture help?

I'm sorry about the check valve.

It's hard to say. Wrap a string around the pipe. Put a mark on the string that hits where the string crosses. Measure the distance from the middle of one mark to the middle of the other mark.

I wrapped a zip tie around and marked where it crosses. Does this help?

4.125/pi= 1.313

I think it is 1 inch.

Thank you, I was panicking.
