Dear experts, I bought a "fixer upper house" built in Memphis in 1920.
All the original water supply plumbing is/was lead from the street meter to each fixture/ The inner diameter of this lead pipe was a little less than 1/2 inch.
Over the years, some people had added assorted copper and pvc here and there under the kitchen. several joints were leaky and the water heater was nasty, so I decided to redo it all since the crawl space is large and easy to work in.
I soldered 1/2 copper to the lead supply line coming out of the dirt, and ran 1/2 copper to everywhere else under the house. It all looks good but the water pressure didn't improve. I have now dug up the main supply line all the way to the street. That's the only original lead pipe still in use.
What size new line should I use there to make things right and improve the pressure?
I would like to leave the 1/2 branch work under the house if I can, but I would like you all to tell how to make it right, whatever that involves. I'm handy and learn fast, but this is my 1st plumbing project other than installing water heaters! Please help!
