Was the switch turned on? It is usually located on the wall in the kitchen area near the sink or stove.
Yes, there is a switch inside the pump that starts pumping when the pressure goes down, like when you turn on a faucet. You do need 12 volt power to the pump terminals before the internal switch will turn on the pump to draw water from the fresh water tank.Is it possible that the on demand switch be located in the Shurflo 2088?
