Overview of the Problem – Insurance Required a Laundry Flood Prevention Upgrade

At a commercial premises on Huntingdale Road in Huntingdale VIC 3166, our team at Your Choice Plumbers was called out after a serious flood had occurred in the laundry area due to failed washing machine connections.

The damage to the premises was significant, and the insurance company made it clear that a full upgrade of the water delivery system was required before they would proceed with structural repair works.

This is exactly the type of situation where business owners start asking, “how do we stop a washing machine flood from happening again?” or “what plumbing upgrades does insurance require after a burst hose event?” As an experienced plumber Huntingdale, we often find that after a major flood, the real solution is not just replacing what failed — it is rebuilding the setup so the same type of event cannot happen again.

Why This Was More Than a Standard Laundry Repair

Once we inspected the laundry area, it became obvious that the flood was not caused by bad luck alone.

The original setup had been installed in a way that was not suitable for the application, and it was also being exposed to unregulated water pressure.

That meant the job was not just about replacing a few valves. It was about correcting the underlying conditions that had contributed to the original flooding event and then providing the owner with a much stronger level of future protection.

Incorrect Tap Fittings Had Been Used for the Appliance Connection

A key part of the diagnosis was the type of fittings being used on the washing machine supply.

The existing “stops” were actually standard external garden taps.

While these fittings have the same 20mm male thread that will physically accept a washing machine hose, they are not designed to be used as a proper internal laundry appliance connection point. In a commercial environment, where appliances cycle repeatedly and fast-closing valves create sudden force in the line, this kind of setup is especially vulnerable.

That meant the original laundry connection arrangement was fundamentally wrong for the job.

High Water Pressure Was the Other Major Risk Factor

Alongside the incorrect tap fittings, the property was also running with unregulated mains pressure.

That was a major issue because high static pressure places continuous stress on:

  • washing machine hoses
  • valve bodies
  • appliance isolation points
  • internal seals and connections

In this type of setup, pressure-related stress can be made even worse by the sharp valve actions of commercial or heavy-use laundry appliances.

This is something we often explain on burst pipe repairs and pressure limiting valve and PRV installation jobs, because failed laundry hoses and appliance connection floods are often pressure-driven events rather than isolated random failures.

Designing a Multi-Layered Flood Prevention Upgrade

Because the insurer wanted a much safer configuration before restoration works could continue, we designed the replacement laundry setup with multiple layers of protection rather than relying on one single change.

The goal was to create a system that:

  • used proper internal appliance connection valves
  • provided automatic shut-off protection if a hose burst
  • reduced the building pressure to a safe level
  • gave the owner a documented, professional upgrade that could be presented back to the insurer

All required parts were sourced from Reece Plumbing Oakleigh.

Replacing the Incorrect Laundry Taps with Proper Valves

We removed the inappropriate garden tap-style fittings and installed:

two Arco Giro Combi Valves (Lead-Free)

These valves provided the laundry with dedicated appliance connection points that were far more appropriate for internal use and far better suited to the demands of the setup.

This gave the system a proper foundation before the higher-level flood protection measures were added.

Installing Burst Protection Isolation Valves

To add a much stronger layer of protection, we also installed a pair of BurstProof Isolation Valves on the washing machine supply.

These are designed to automatically shut off the water if they detect a sudden abnormal change in flow, such as what happens when:

  • a hose bursts
  • a major connection fails suddenly
  • water begins escaping uncontrollably

That meant the laundry system was no longer relying purely on manual shut-off response. It now had an automatic safeguard built into the appliance supply arrangement itself.

This is exactly the kind of layered protection that makes sense in properties where previous flooding has already occurred and insurance expectations are higher.

Pressure Regulation at the Meter

To protect the entire building and remove the broader pressure-related risk, we also installed an in-line Zurn Pressure Reducing Valve (PRV) at the meter.

This brought the building’s pressure down to a safe and compliant level, which reduced stress not just on the laundry setup, but also on the wider plumbing system serving the premises.

That was a critical part of the project because without correcting the pressure, even upgraded fittings and valves would still be working under unnecessarily harsh conditions.

System Testing and Commissioning

Once the new laundry safety configuration was installed, we tested and commissioned the system to ensure everything was operating correctly.

This included confirming:

  • the new valve arrangement was functioning properly
  • the pressure reduction was stable
  • the safety shut-off valves were responding correctly under simulated failure conditions
  • the laundry setup was ready to be documented back to the insurer as an upgraded, professionally installed system

That final stage mattered because this was not just a plumbing repair — it was an insurance-driven compliance and flood mitigation upgrade.

Why This Upgrade Was the Right Long-Term Outcome

The owner did not just need the damaged setup replaced. They needed the laundry area rebuilt in a way that made a repeat flood event far less likely.

By upgrading the system with:

  • proper appliance valves
  • automatic burst shut-off protection
  • pressure regulation at the meter

the premises now has a much stronger and more defensible plumbing setup than it did before the incident.

That is what gave the insurer and the owner confidence to move forward.

Final Result and Client Outcome

Once the works were complete, the business had:

  • the unsafe garden tap setup removed
  • new Arco lead-free appliance valves installed
  • BurstProof isolation valves protecting the washing machine supply
  • a new Zurn pressure reducing valve at the meter
  • a much safer commercial laundry configuration
  • documentation ready to support the insurance restoration process

The owners were very pleased that the upgrade addressed not just the failed components, but the real pressure and flood-prevention issues behind the original event.

Compliance with Australian Standards

This case directly related to the pressure control requirements referenced under AS/NZS 3500, which requires plumbing systems to operate within safe pressure limits, together with the broader expectation that appliance connection points and water service components be suitable for their intended use.

In practical terms, this meant the solution was not simply replacing what had failed. It was about rebuilding the laundry water supply so it was safer, more appropriate for the commercial setting, and far better protected against another flood event.

All work carried out by Your Choice Plumbers is completed in accordance with the relevant plumbing standards so flood-prone appliance setups can be upgraded properly and documented clearly where insurers or property managers require it.
