Who knows what kind of pressure past owners put on it. I will be using a brass RV water regulator on it.

I don't know if the water system has any burst places (more likely from lack of winterizing, than it being Poly B from the sound of it) so I will just have to see how it holds up when I hook a hose to it.

I do at least need to replace the city water hookup itself. It is partly broken somehow and loose. But that just threads on to a brass fitting on the end so that won't be a big deal to replace if all of the rest of the system is sound.
The problem with some of the early 90s era poly b I've encountered during retrofits was even with the copper fittings was that the pipe had become brittle after a number of years exposure to chlorinated water and any flexing during work would cause fittings to start leaking.

From the look of the pipe in your rig, it looks more like poly E than poly B.
