This is what my current setup looks like in the basement:

It's a 1996 home which appears to have had the original PB replaced with CPVC, except for this remaining PB at the inlet and some PEX elsewhere for a tankless water heater.

My plan is to remove the valves and CPVC in the picture and use PEX to go to a ball valve, then a pressure valve, then a whole-house filter, then another ball valve, then back to the CPVC.

So, should I leave that vertical piece of PB and just cut off the copper and go directly to PEX with a PB to PEX fitting? Seems like it would be difficult to get rid of that piece of PB.

Should you get rid of it? Yes. Will you? No. If your getting rid of that you'd need to get rid of the pb that is hooked to which means digging out your existing service and replacing it with material that isn't terrible.

I guess it depends how motivated you are. I'd probably leave it. Someone did a good job transitioning. You'll have to find a transition fitting. I would probably just go from cpvc to pex.

That vertical plastic pipe adjacent to the PB pipe looks cocked in its top fitting. Illusion?

Not sure I follow you but Id love to get rid of all the PB but little interest in getting rid of just that one piece. Id like to get rid of The CPVC depending on age as well 15 plus years old Id have more motivation than CPVC thats only 5 years old . Pick your battles

I thought about just cutting the CPVC. Then I would have PB->Copper->CPVC->PEX. That just seems... messy.

I think that's a good summary. All my search results basically said to panic and rip out PB as soon as possible, assuming the whole house had PB, so I wanted to get a clearer picture on how necessary it is to remove every last scrap.

I checked and it's about 95% illusion. The camera angle and the clamp bending the pipe in that direction is making it look much worse than it is. I removed the clamp and it looks maybe just slightly off.

Well, I found dates on the CPVC ranging from 2011 to 2003. But I'm really not sure how much longer we will stay in the home. I have a Ring alarm and several flood sensors, with one of them directly below the area pictured.
