Why choose Giant for fire service repairs

  • Hundreds of repairs

    We have carried out hundreds of burst fire service repairs across Victoria, on copper, steel and other fire service pipework.

  • Leak detection and excavation in-house

    Our own leak detection equipment locates the leak and our own excavators expose it, so most of the job stays with us rather than several contractors.

  • Licensed for hydrants and backflow

    Our plumbing licence includes the fire protection class for hydrants and the backflow prevention class.

Frequently asked questions

How do I know a fire service is leaking?

The usual signs are water coming up through the ground, a loss of pressure in the fire service, and water use that is higher than it should be.

Can we reach you after hours?

We attend burst fire services outside normal hours, and 1300 159 857 reaches us after hours.

What if access is difficult?

Concrete cutting and difficult access are common on these jobs, and we handle both ourselves.

What if the burst shows a bigger problem?

A burst can expose badly corroded pipework, a poor previous repair or an ageing underground service. Where it does, we quote that work before it starts.

Do you work for other plumbing contractors?

Yes. Other plumbing contractors pass their burst fire service calls to us, and we work directly for property, facility and asset managers.
