If you have galvanized pipe in your house, now might be a good time to

You gotta be kidding.....
Galvanized pipe is some of the most durable pipe made.
I dont plan to sell the house, and if some insurer told me I'd have to
replace my steel pipes, I'd quickly tell him he needs to change his
job.... (and show him the door).

And this pipe is not in the house, it's in an underground concrete pit,
where my well storage tank is located. I would not even consider any
other type of pipe in that location. My entire farm is fed from this
pipe.

water flow decreases over time because of rusting from the inside..

till you have no flow, about that time it will begin leaking at all fittings.

if your current homeowners insurance company is sold, gets too expensive or finds out you have this plumbing, bad sidewalks, a fire, or other loss they will require these lines be replaced, bad sidewalks replaced, porches be repaired, new roof, upgrade to circuit breakers, replace all knob and tube wiring. etc etc. heck someone visting trips and you will be getting a visit by the homeowners insurance company inspection service

PEX is so easy to work with, and cheap,
