Hello everyone, Was hoping someone can help me get started. I got new counter tops installed and now I need to get my plumbing re-connected. The installer said a plumber can charge a few hundred for this. Do I really have to hire someone for this? Can someone explain what tools and other items I may need to get this done? I have to re-connect my garbage disposal, all the piping and my faucet to the water lines & on top of the granite. FYI, my sink is under mount if that matters. Thank you all for your help.
