ok I bought a house last year. has old galv. pipe. most of which is ok, **** there is a few bad spots and am going to need to replace the whole house plumbing eventually. has any DIY done this? all at once or section by section? Im pretty confident in my soldering and gluing. so what is better copper of cpcv? I’d rather glue than solder in my crawl space. maybe copper for the hot waterlines and cpvs for cold?

Copper is great, but expensive. Price of copper went through the roof a few years back and hasn’t come down yet. I took out all my old galvanized a couple years ago. I replaced the cold water lines with PVC and hot water lines with CPVC. I got a bunch of friends together with their sawz-alls and we ripped the whole thing out at once. Cut and glued the new in and waited 24 hrs. to let it cure. But I was working in a basement, not a crawlspace. Might do it in sections if the old pipe will come apart at the joints without breaking.
Use flexible PEX pipe, its made of polyethylene plastic and it works awesome, no glueing needed or soldering. Much cheaper than copper
pvc for all. if you need to connect to galv. or copper there are transition connectors. make sure the building code allows pvc or copper. copper is super expensive. when attaching the hot water pipe to the joist, put a piece of hard foam or rubber between the pipe and joist to prevent noise from expansion.
Go with PEX or CPVC. Copper is expensive and difficult to get the hang of if you don’t have experience with a torch. Copper doesn’t really gain you anything either. PEX may be the way to go in the crawlspace, as it is flexible.
