All of the pipes in my house are either copper or PEX. There's just one pipe that I'm not sure about. It's the main water supply line as you can see in the picture. Further up, it connects to a copper pipe. I've also attached a close-up picture of the writing on the pipe. The only information I could gather from this text is that it's a fire resistant pipe, but I'm still not sure what type of pipe it is. I'm just worried that it might be a Poly B pipe. Unfortunately, the remaining part of the text is underground so impossible to see without digging the ground. Any thoughts?
