The non-negative pressure water supply equipment of the device, this kind of non-negative pressure water supply equipment uses the water in the steady flow tank as a supplement when the municipal water supply is insufficient. If the water volume drops again, the equipment will implement the second pressure to ensure uninterrupted water supply. Until the water in the steady flow tank is completely supplied, the equipment will automatically stop. However, this non-negative pressure water supply equipment cannot adjust the operating conditions of the booster pump in real time according to the changes in the user's water consumption and incoming water flow, resulting in serious waste of electric energy, and when the municipal water supply decreases, the continuous water supply time of the equipment is short.
