DIY- Not enough hot water|Water heater temperature knob settings

how can you do if you don't have enough hot water, let's see the bottom of the water heater tank. there should be a gas valve and dial on the gas valve, we can see low a b c very hot, the knob temperature setting shown you here, and you can adjust by your requirement, but normally setting b is enough for you. we don't recommend setting to very hot that may be triggered. relief valve and flooded basement.

This just increases the temperature of the hot water. It will still run out because this doesn’t give you more hot water. Once the tank is empty, it takes time to heat back up

I don’t have any hot water in my mobile home heater. What can I do? I don’t want to call a plumber. I want to troubleshoot it myself before I do call a plumber.
