What problems should be paid attention to in the selection of water supply equipment?

1, the domestic water supply system adopts frequency conversion water supply mode without negative pressure. The local water supply department should agree to install variable frequency and constant pressure water supply equipment.

2. In conventional water supply, the total amount of water can't reach the total amount; The pressure of water supply network is small, the pressure fluctuates greatly, and the diameter of water supply pipeline is small. The water supply unit thinks that frequency conversion and constant pressure water supply equipment cannot be installed. It is not suitable for use in the field without negative pressure variable frequency water supply.

3. When the water consumption is relatively concentrated, the water consumption is large or the water supply guarantee rate is high, the water consumption should be considered when selecting the stable water tank when using the variable frequency constant pressure water supply equipment.
