Drain: prevent freezing and cracking in winter.
3.Flange base: connected to the underground water supply network and fixed to the concrete base

Type Classification

2.By regional standard: domestically, GB 4452-2011 "Outdoor fire hydrant" standard is usually followed; internationally, there are different interface specifications (such as American standard, European standard).

Installation Specifications

1.Location: Along roads, communities and other public places, with a spacing of ≤120 meters, ≥5 meters from buildings, and easy to reach.
2.Pressure requirements: The water supply network needs to maintain a working pressure of 0.1-0.5MPa to ensure sufficient water output.

Use And Maintenance

1.Operation steps: Open the interface cover → Connect the water hose → Use a wrench to open the valve stem counterclockwise.
2.Notes: It is strictly forbidden to use it in non-emergency situations; drainage and anti-freezing are required in winter.
