Water Service Repairs

Melbourne

Repairs, replacement and maintenance of water mains and water services on industrial and commercial sites, including leaks, failed valves and backflow prevention devices.

Water Service Repairs and Replacement for Industrial and Commercial Sites

A burst or leaking water main on a large site wastes water, undermines slabs and roads and can leave production and amenities without supply. Older copper, galvanised steel and early plastic services are reaching the end of their life on many Melbourne industrial estates.

SWR Plumbing repairs, replaces and maintains water services for industrial and commercial properties. We find the leak, isolate it with as little disruption as possible and repair or replace the failed section.

Water Service Work We Do

  • Leak location and repair: finding and repairing leaks on underground and above ground mains.
  • Water main replacement: replacing aged or undersized services with modern materials.
  • Isolation valves: adding and replacing valves so sections can be isolated without shutting down the whole site.
  • Backflow prevention devices: installation and maintenance of devices protecting the drinking water supply.
  • Pressure and flow issues: diagnosing low pressure and installing booster connections.
  • New connections: water supply to new buildings, equipment and amenities.

Less Disruption, Better Isolation

Many older sites have only one or two isolation valves, which means any repair shuts down water to everything. When we repair a main we look at adding isolation valves so future work can be done section by section.

Where a full replacement is needed, we plan the work so temporary supply can be maintained where possible and the final changeover happens in a planned window.

For hidden leaks in homes and smaller buildings, see our leak detection service.

Water Service FAQs

How do you find a leak on an underground main?

We use a combination of isolation testing, meter readings, listening equipment and site knowledge to narrow down the location before excavating.

Should we repair or replace an old water main?

One leak can be repaired. Repeated leaks on an aged service usually mean replacement is more economical. We give you both options with prices.

Do you install backflow prevention devices?

Yes. We install and maintain backflow prevention devices where the site’s hazard rating requires them.

Will the whole site lose water during repairs?

Not always. Where valves allow, we isolate only the affected section. We also add valves during repairs to make future work easier.

How much does a water service repair cost?

It depends on depth, surface type and access. We quote after locating the problem.
