Indoor fire hydrant installation and maintenance matters needing attention

Release time:


1. After installation, the garbage and impurities in the fire-fighting pipeline must be removed; when the valve is closed, the valve flap seal is never allowed to stick to sand, white paint and other impurities.

2. After installation, open the valve regularly (usually half a month) to prevent the valve disc gasket from sticking to the valve seat and damaging it.

3, always check the valve sealing gasket and interface gasket is aging and damage; found that the damage should be replaced in time.

4. Conduct regular water discharge inspection to ensure that the water can be opened in time when a fire occurs.
