If you are connected to the camp site water (shore water) it is pressurized and will feed everything inside your coach. If you want to use the water in the fresh water tank, disconnect shore water (or close the spigot) and turn the pump on. Everything in your coach will be fed by the water in the tank. Another option is to use well water for everything except for drinking. We always bring bottled water. Yet another option would be to install an inline water filter.
