Demand Water Pump - dumb question
Our rig has a "demand" water pump. I know that when the pump is powered, it'll come on if the outside water pressure drops below a certain point. What I don't know is where the pump is then getting...

When the shore water pressure is low and our water pump is turned on, the water pump will try to raise the pressure by pumping more water. The water comes from the on board tank. If there is no water in the tank, the water pump will still run to try to improve the pressure. We always keep water in our on board tank so the pump increases the water pressure in low pressure situations (like the one we had yesterday).
