The Benefits of Sprinkler Tank Relining

Sprinkler tank relining is a crucial maintenance procedure designed to extend the life of fire protection water storage tanks. Over time, tanks can suffer from wear and tear, corrosion, and leaks, compromising their integrity and functionality. Relining is a cost-effective alternative to complete tank replacement, addressing issues and restoring the tank to a fully operational state.

Why Relining Is Necessary

Relining is necessary for several reasons:

  • Preventing Leaks: Over time, tanks can develop leaks due to corrosion or physical damage. Relining seals these leaks, ensuring that water is available for fire suppression.
  • Corrosion Protection: It provides a new protective barrier against corrosion, which can significantly extend the tank’s service life.
  • Water Quality: Maintaining the internal condition of the tank helps prevent contamination of the stored water, which is crucial for systems where water might be used for purposes other than fire suppression.

The Relining Process

The relining process typically involves the following steps:

  1. Inspection and Cleaning: The tank is thoroughly inspected for damage, and all surfaces are cleaned to prepare for the relining material.
  2. Application of Relining Material: A new lining material, often epoxy or a similar durable substance, is applied to the tank’s interior surfaces. This material is selected for its water resistance and ability to bond with the existing tank material.
  3. Curing and Quality Check: The relining material can cure, forming a solid, protective layer. After curing, the tank is inspected to ensure the lining is intact and leak-free.

Advantages of Tank Relining

  • Cost-Effectiveness: Relining is generally more affordable than replacing an entire tank, especially for large or custom-built tanks.
  • Less Downtime: The process is faster than tank replacement, minimising the time the fire protection system is out of service.
  • Environmental Consideration: By extending the life of existing tanks, relining contributes to waste reduction.


When considering tank relining, it is essential to work with experienced professionals specialising in fire protection systems. They can advise on whether relining is the best option based on the tank’s condition, age, and the specific requirements of the fire suppression system.

In conclusion, sprinkler tank relining is an effective maintenance strategy that can save time and money and ensure fire protection systems remain operational and effective for years. It’s a vital part of a comprehensive maintenance plan, ensuring the reliability and efficiency of fire suppression efforts in commercial and residential buildings.
