If all the faucets are turned off (check the outside shower) and the water heater is full, if there are no leaks and the city water connection isn't "flowing water out the hose fitting" then there should be no reason for the water pump to continue running. In other words, if you aren't "losing water" then the pump should stop....
There is a pressure switch in the pump head. In theory, when you open a faucet, the pressure drops and the switch in the pump head turns on the pump to supply pressure until you close the faucet. When closed, pressure will build up in the lines and the pressure switch will turn the pump off.
If there is "pressure leakdown" around that pressure switch, the pump will continue to run because the pump can't build pressure. This could be caused by a defective pressure switch, a hole in the pump diaphragm or a piece of trash (construction debris) that was pulled up from the fresh water tank. You can disassemble the pump head, check for damage or debris, reassemble and it may work. Otherwise, you can buy a new pump head for about $30 or a new pump for about $40.
Before you disassemble the pump head or buy a new pump, be sure that there isn't a hidden leak that you're missing.
