Thanks for the updates. Renovations are sometimes complicated, time consuming and expensive, we know that. Just do little at a time.
- Don't mix copper with galvanized. Remove and replace all galvanized parts in there. Brass can stay.
- A stub out for a sprinkler system should be before the main water supply enters the house. Don't forget to install a shut off valve on the stub out. Also, what's the pressure at the meter?
- How far is it from the house to the water meter in the street? I'll tell you why I'm asking: I don't like it to be type K copper. I rather have type L copper.
