It's an Atwood heater with a nylon drain plug. Let it cool off and turn off water pump. Open a hot side faucet in the RV to relieve pressure. Then remove that big plastic nut to drain the tank. You really don't need to open the pressure relief valve, it will still drain. While the tank is draining go inside and lift the bunk to access the back of the water heater. Set the valves to the bypass position to isolate the water heater tank.
Now go back outside and put the plug back in finger tight. Put the socket on the plug and give about a 1/12th turn. Picture the plug being a clock face and turn it from the 12:00 position to the 1:00 position. That's it, there is no need to go tighter unless it seeps or leaks. Honestly 1/12th is probably still turning it more than you have to.
