Hey "Old Dog" I'm an old dog too. Been doing home repairs for 36 years. It's not easy doing some things AFTER it's done. I once worked on a job of building a "Club" back in Illinois and the bar was installed. Almost 30 feet of beautiful bar and all the tile work done. When they came in to install the beer taps and misc. They found that there was no piping to run the lines from the cooler to the bar!! Someone screwed up big and it cost about $20,000 to tear up the tile and concrete to run the 4" PVC runs for the hoses!!! Think of what you want to accomplish and make sure to make a schedule!!
