I swapped out my propane grill for a natural gas grill. There is a gas line stub with a shutoff valve at the right spot on the deck. I've never messed with natural gas before. Any reason this isn't something I can do myself? It looks as simple as removing the "plug" from the wall line with a wrench, hooking up the flexible hose, turning the valve on, and checking for leaks with soap and water... Should I use teflon plumber's tape as well?
