      You can replace the lines with PEX, but you will have to support them more frequently than if you use copper. The manifolds would have to be black pipe or copper because there are no plastic manifolds, so the plastic would have to be connected with expensive connectors to their manifolds and the copper lines going upstairs. You would have short lines of plastic connecting between the manifolds and the lines. It would be better and more secure to just use copper.
