Buying Home - galvanized pipes?

Galvanized water lines rust from the inside and will eventually start leaking. The rust inside also starts to constrict water flow so you don't get as much water coming out of the facet. Hot water lines seem to be worse than cold. My experience is the line running from the meter that is buried will leak long before pipes in your walls. I have replaced that main line and much of the pipe in the walls that I could easily get to. But there are some pipes that would require tearing out sheet rock to get to so I'm hoping that don't start leaking.

I replaced all the incoming plumbing in the house I'm currently living in when I bought it in 92. The house was built in the late 20's and had galvanized pipe for the water supply and it would take 20 minutes to get enough water in the tub to take a bath------completely forget about taking a shower.

I replaced all my lines with copper and it's been no issue since, but I did demo the ground floor ceilings and walls to allow easy access to all water lines since I was going to restructure the ground floor anyway and go back new. I only had 3 places upstairs with water----the kitchen, bath and wash room, so running those lines was a snap.

When I pulled the galvanize pipe, they were almost completely clogged with rust and mineral deposits with some areas no bigger than a lead pencil point clearance.

If PEX leaks it's due to faulty installation, not the PEX tubing or fittings themselves. PEX isn't forgiving of sloppy workmanship unlike copper or threaded fittings but it will out last anything when done right. My house is pier-and-beam and I've replaced all the lines under the house with PEX over the years as well as the plumbing fittings into the kitchen and master bath. No leaks and no worries if we get a hard freeze.
