Lots of great suggestions here! Thanks Alicia. I do need to get a non contact voltage tester. I just have a multimeter, which requires you to touch exposed wires, so getting one of those would be much safer. You’ll have to let me know how that gas detector works if you get one. I’m curious to know how they work. I thought that was really smart about using a hose clamp and a piece of bike tire to temporarily fix a leak in a copper pipe.
