Socket wrench size for water heater?
I have a 2021 Jayco 212QB TT. Does anyone know what size socket wrench I need to empty the water heater in the winterizing process? The TT is stored over an hour from me so it's not easy to go check on it. I was out there today and had a 3/4" but it was too small. Held a tape measure up to it and it seems like 15/16" but I could be wrong. A second socket set I have at home has a 13/16", so I'm wondering if I need to buy a larger set before I head back to the trailer.
