Our house was built within 1992. The faucet is old and requirements to be replaced. At one point we had purchased a Moen faucet, but the up to date faucet had approaching rigid pipe connections whereas the old one have what appears to be soft copper much smaller pipe connections. I'm just wondering if this is something specifically not easily done. Do they still provide the faucets with the soft copper lines? Or do we involve a plumber to do this?

If your asking this cross-question... Get a plumber. It'll cost you allot less in a minute than if you do it yourself and the line leak or breaks when your not around. They can usually do it for around a hundred dollars or less..
