Rust, Cracks or Leaks: Which Water Tank Problems Need Professional Repairs?

 Rainwater tanks can develop visible problems over time, including rust, cracks, leaks and damaged fittings. Regular inspection helps identify issues before they become more serious. But which problems require professional attention? The answer depends on the type, location and severity of the damage.

Rust and Corrosion: Check the Extent of the Damage

Rust is particularly relevant to steel water tanks. Steel tanks can be supplied with protective coatings or internal polymer linings designed to reduce corrosion. Damage to these protective layers can increase the risk of corrosion. 

Surface rust may need assessment before you decide whether repair or replacement is appropriate. Extensive corrosion, damaged tank surfaces or corrosion affecting connections should be assessed by someone experienced with the tank material and construction.

Cracks: Don't Ignore Structural Damage

Cracks deserve careful attention because their significance depends on their size, location and cause. Australian home-maintenance guidance recommends professional advice for potentially structural cracks rather than treating every crack as a simple cosmetic defect. 

Professional assessment is particularly important when:

A crack is increasing in size.

Water is escaping through the damaged area.

The tank shows signs of movement or structural damage.

The crack is located around an important connection or fitting.

For significant cracking, attempting an unsuitable DIY repair could fail to address the underlying problem.

Leaks: Find the Source Before Repairing

A leaking tank should be inspected to determine where the water is escaping. The problem may involve the tank itself, pipework, fittings, connections or other components.

We recommend regular inspection of tanks and related components, with defects repaired promptly. 

Professional Water Tank Repairs Brisbane services can assess the source of the leak and determine whether the affected component can be repaired or needs replacement.

Damaged Screens and Fittings Also Need Attention

Water tank problems are not limited to the tank body.

Other components worth checking include:

Inlet and outlet screens

Overflow fittings

First-flush devices

Pipes and connections

Tank access points

When Should You Call a Professional?

Consider professional Rainwater Tank Repairs Brisbane when you find significant corrosion, structural cracks, persistent leaks or damaged components that affect the tank's operation.

If you notice rust, cracks or unexplained water loss, arrange an assessment before the problem becomes more difficult to repair. Professional Water Tank Repairs can help determine the appropriate repair approach based on the tank's condition, material and damaged components.
