Hi All,
Got a 3 bdrm 1 bath house with galv pipe; replacing from the meter (about 45' away) to the house w/copper.
Couple of questions:
1. There's currently a shutoff valve at the meter and appears to be another shutoff at the house outside, just before the pipe goes under the house into the crawl. Do I need to keep the shutoff at the house? From what I've read about this, you don't want any underground joints in the copper if possible. But if I install a valve at the house, that would certainly require joints underground.
2. Measured the current pressure at the house is about 60 psi. Haven't measured to old galv pipe size as yet but it appears to be at least 1". Could I get by with 3/4" copper or should go with 1"? Was planning on using L grade soft copper or is K required for underground? I'm portland Or area; water Ph is fine (corrosion not an issue).
Thanks for any tips. Background: I'm DIY; have done lots of copper replacement, but not underground before.
