Thanks- I'll be using a plumber. Just wanted to know if I could source fixtures that would allow using the same wall location.1. We do not stub out that far anymore. We stub close to wall and use flex lines up to the faucet.
2. Lavatory sink pop-up drain in all metal is available readily as are chrome p-trap.
3. You need a plumber.
Probably both. The water is very acidic and there is a lot of corrosionWhat are you planning on replacing? Drain lines, or water lines
