Whether residential or building a normal person may make many repairs to the plumbing system before calling in an expensive trade person.
There exist two separate systems in your home or building. One system brings treated “fresh” water into the structure and the other system takes “waste” water out.
The fresh water is under pressure, as produced by pumps and this fact allows this water to be distributed throughout the structure.
The water as it enters the structure is metered which allows the water used to be monitored.
The main water shut off, is a valve which is located adjacent to the water meter and this is the valve to be closed if there is a pipe burst or major leak in the house.

How to plumb states that as water comes into your home, it passes through a meter that registers the amount you use. The main water shutoff, or stop, valve is typically located close to the meter. In a plumbing emergency, it's vital that you quickly close the main shutoff valve. Otherwise, when a pipe bursts, it can flood your house in no time. If the emergency is confined to a sink, tub, or toilet, however, you may not want to turn off your entire water supply. Therefore, most fixtures should have individual stop valves.
The water available from the main supply is ready for any and all cold water requirements and is referred to as the domestic water system.
The building hot water system requires that domestic cold water is fed to some kind of heater. In a house, it will be hot water heater which is usually gas fired or has electrical heaters. A thermostat on the heater turns the heat section on and off to maintain a preselected tank hot water temperature. This temperature may be as high as 160F but is usually set at 140F. It is suggested that with today’s high energy costs the domestic hot water temperature may be set as low as 120F.
In a commercial facility the hot water heaters will be larger and capable of a much greater volume of water. To move this water around the building it is usual that this system be complete with pumps, which turn on and off to maintain building domestic hot water line pressure.
