It is literally always hungry and massively obese, because the normal satiety signaling hormone â leptin â is absent from circulation. Researchers typically use the ob/ob mouse as a model for type II diabetes. When you inject an (obese) ob/ob mouse with leptin, it loses weight and its health markers normalize.
The tank pressure sensor is usually located on the top of the fuel pump assembly.
When the water in the pressures tank drops below the required amount, a pressure switch is activated turning on the pump. The pump then refills the pressure tank. The combination of the pressure tank, pressure switch and the pump is what allows water to flow through your home. Pressure tanks, which also act as reservoirs for the home, are generally set to keep pressure within 20 pounds per square inch (PSI) of your starting and stopping parameters.
