Fire Hydrant Systems Installation & Maintenance

AS1851 is the Australian Standard for the Routine Servicing of a fire protection systems and equipment. In certain circumstances, it is vital that we know the installation Standard that a fire protection system or equipment has been installed and approved ("the Approved Design") in order for us to have a reference point for comparative performance.

Fire Hydrant System Block Plan

Australian Standard AS 2419.1 sets out the requirements for the system design, installation and commissioning of a fire hydrant installation.  Like most Australian Standards this Standard is revised and updated from time to time to reflect changes in best practice and community expectations.

The history of the Standard dates back to 1980;

  • AS 2419:1980 
  • AS 2419.1:1988
  • AS 2419.1:2005
  • AS 2419.1:2017

With each subsequent edition of the Standard there are different expectations of performance of a Fire Hydrant System.

The Ultimate Fire Hydrant System Maintenance Checklist

Don't be confused by the industry language that a "hydrostatic test" is the same as the "five-yearly service"... it's not, the five-yearly service is much, much more than just a hydrostatic pressure test!

Routine Servicing of Fire Hydrant Systems

For routine servicing, this is important because AS 1851 provides a methodology for undertaking the routine servicing but typically does not set out the performance requirement, while AS2419 provides the Standard of performance for subsequent comparison.

Prior to conducting the routine (yearly) flow test or (five-yearly) hydrostatic pressure test, a person conducting the routine service will require specific performance details for the original installation.

For a fire hydrant system this information typically includes the following data which can be found on the block plan, commissioning documentation, operation and maintenance manuals;

  1. Height of the highest fire hydrant landing valve above the booster;
  2. Standard of Performance for the system design (i.e. AS 2419.1:2005)
  3. System Hydrostatic Test Pressure (i.e. 1700 kPa)
  4. System Flow & Discharge Duties (i.e. 20 L/s at 1030 kPa)
  5. Installation Contractors Name
  6. Installation Date (DD/MM/YYYY)
  7. Total number (quantity) of hydrant landing valves

Of particular importance here are items 2, 3 and 4 as they provide the baseline for comparison for subsequent tests set out in AS1851.

This is not a exhaustive explanation of the relationship between the System Design, Installation and Commissioning Standard for Fire Hydrant Systems and the Routine Servicing of Fire Hydrant Systems but it does provide a basic framework for people to understand the relationship between the two Standards.
