This chapter will be about getting started with Git. We will begin by explaining some background on version control tools, then move on to how to get Git running on your system and finally how to get it set up to start working with. At the end of this chapter you should understand why Git is around, why you should use it and you should be all set up to do so.
It might be the water fill valve was left open by mistake. This is a valve that allows filling the water tank from the fresh water pipe, when you are in a campground, and if left open can cause the water pump to run, as the water is going from the pressurized fresh water line back into the tank.
If it's a gas water heater then they may think their gas valve is broken or the pilot light or the thermocouple quit working. Flush - every year or so, you should flush the water in your water heater. This helps to wash out sediment build up in the tank, preserving the life both of the tank and the heating element. Drain - if you shut down your water heater during the winter, you should drain the tank entirely to prevent flooding while you're away.
