With our water pump, you turn the switch on and leave it on. If you are going to be using the tank alot don't forget to fill the water heater first or you will use 10 gallons of you water right away. Once the pump has brought the system up to pressure it should shut off and not start back up until a faucet is opened. If it comes on before that you have a leak somewhere in the system. I like the idea of two swithches, we only have one in the kitchen. We will turn ours off when we aren't going to be using it for a period of time, just as a precaution.
