Roof overflow is not siphon rain, but when the downpipe blocked rainwater can not be properly discharged when another drainage. The overflow port is located at a height of about 300mm on the roof. When the rainwater accumulates to 300 inches above the roof, it is discharged from the overflow port. 300 below still need to drain through the drain.
Constant pressure overflow effect: In the metering pump throttling regulation system, the dosing pump provides a constant flow. When the system pressure increases, will reduce the demand for traffic. At this point, the relief valve is opened to allow excess flow to overflow into the fuel tank to ensure that the relief valve inlet pressure is constant, ie the pressure at the pump outlet is constant (the valve port often opens with pressure fluctuations).
