How to Properly Maintain a Fire Water Tank on a Daily Basis?

A fire water tank is a vital component of a fire protection system, ensuring a reliable supply of firefighting water during the early stages of a fire, particularly when municipal water pressure is low or fire pumps are not yet operational. Its main functions include providing firefighting water, stabilizing system pressure, and serving as an emergency water backup.

What is the function of a fire water tank?

Initial fire-fighting water supply

During the early stage of a fire, the fire water tank supplies water to sprinkler systems, fire hydrants, and other fire-fighting equipment, helping to control the fire quickly.

Pressure stabilization

The fire water tank helps maintain stable pressure in the fire pipeline network, ensuring that sprinklers, hoses, and nozzles operate effectively.

Emergency backup water source

In case of municipal water supply interruption, low pressure, or pump failure, the fire water tank serves as an emergency reserve to guarantee continuous fire protection.

Common types include stainless steel fire water tanks, FRP (fiberglass) fire water tanks, and galvanized fire water tanks, which can be customized according to project requirements.

How should a fire water tank be maintained?

Regular inspection and maintenance are essential to ensure the safety, reliability, and long service life of a fire water tank.

Monthly inspection

• Check water level and ensure it meets design requirements
• Inspect float valves and inlet valves for proper operation
• Ensure overflow and drain pipes are unobstructed

Quarterly maintenance

• Remove sediment from the tank bottom to maintain water quality
• Test the automatic water replenishment and level control system

Annual comprehensive inspection

• Check for corrosion, deformation, or leakage of tank panels
• Pay special attention to weld seams, tie rods, and structural joints
• Evaluate the overall structural integrity and service condition of the tank
