Overview of the Job – Kitchen Mixer Replacement and Hidden Plumbing Risks

At a property on Woodmason Street in Malvern VIC 3144, our team at Your Choice Plumbers attended to replace an aged kitchen sink mixer tap with a new gooseneck mixer.

Once the tap replacement was completed, the owners asked us to carry out our Complimentary Property Protection Audit, which they had seen on our website and wanted done because they were not aware of the hidden plumbing risks that can lead to sudden internal flooding.

This is exactly the type of situation where homeowners start asking, “how do I know if my flexi hoses are dangerous?” or “can old hoses under sinks and toilets cause flooding?” As an experienced plumber Malvern, we often find that many properties have hidden flood risks sitting in plain sight, especially around sinks, toilets, and washing machine connections.

Why the Complimentary Property Protection Audit Matters

We explained to the owners that every completed plumbing job with Your Choice Plumbers includes our Complimentary Property Protection Audit to help protect the home from preventable water damage and compliance risks.

As part of that process, we check for issues many homeowners do not realise are putting their property at risk, including:

  • excessive water pressure above 500 kPa
  • flexible braided hoses that are rusted, swollen, poorly supported, or nearing failure
  • hot water temperature concerns, including scalding risks
  • visible signs of ageing plumbing components that may fail unexpectedly

This is particularly relevant on tap and fixture jobs, because repeated failures are often a sign of broader plumbing system stress rather than just one isolated component problem.

What the Audit Found – Rusty Flexi Hoses and Aged Appliance Connections

During the audit, we found several issues that the owners had not previously noticed.

The most important findings were:

  • rusty flexible hoses under the laundry tub connecting to the older sink mixer
  • a rusty toilet flexi hose connecting the mini stop to the toilet cistern
  • aged washing machine hoses that were well beyond the recommended replacement window

These were exactly the kind of hidden issues that can sit quietly in the background until one day they fail and cause major internal water damage.

We documented all of these findings in our report, including the location, condition, and priority of replacement for each affected hose.

Water Pressure and Hot Water Temperature Checks

As part of the audit, we also checked the mains water pressure by connecting our pressure gauge to the front garden tap.

The result confirmed the property was operating at a safe and compliant pressure of 500 kPa or less. The home already had a pressure reducing valve installed, so this check also confirmed that the valve was still operating correctly.

We then checked the hot water temperature at the bathroom tap outlets using our Pocket Temp Digital Probe Thermometer and recorded a compliant delivery temperature of 48°C.

The home had a Rinnai 26 continuous flow hot water system set to 50°C, which meant the system was already regulating hot water appropriately to reduce scalding risk.

This was a very good result, because it showed the home was already protected in two major areas:

  • compliant pressure control
  • compliant hot water temperature delivery

Preventative Plumbing Work Carried Out

Because the owners wanted to deal with the identified risks before they turned into a flooding event, we proceeded with the recommended preventative replacements.

We replaced:

  • the laundry mixer tap, including new flexible hoses
  • the toilet flexi hose
  • the aged washing machine hoses

This turned the job from a simple mixer tap replacement into a much bigger property protection outcome for the home.

Why Flexi Hoses Matter So Much

We explained to the owners that flexible braided hoses are one of the most overlooked flood risks in the home.

Many people simply do not look under laundry tubs, behind toilets, or behind washing machines closely enough to spot:

  • rust staining
  • corrosion
  • bulging
  • ageing rubber internals
  • poor support or twisting

That is why audits like this are so valuable. The owners were genuinely surprised by the condition of the hoses and were relieved the issues had been discovered before they escalated into a failure.

Outcome and Client Result

  • new gooseneck kitchen mixer installed
  • Complimentary Property Protection Audit carried out
  • rusty flexi hoses identified and documented
  • compliant water pressure confirmed
  • compliant hot water temperature confirmed
  • laundry mixer hoses, toilet flexi hose, and washing machine hoses replaced

The owners were very happy to have these hidden issues uncovered early and even happier that they could fix them before they turned into a major flooding event.

Compliance & Prevention Insight

This case highlights why a standard plumbing visit can be the perfect opportunity to identify much bigger hidden risks around the home.

In this case, the original reason for the visit was a kitchen mixer replacement, but the real long-term value came from the audit findings. Without that extra step, the rusty hoses under the laundry tub and at the toilet could easily have remained unnoticed until one of them failed.

It also reinforces why checking:

  • water pressure
  • hot water delivery temperature
  • flexible hose condition

is such an important part of protecting a home from preventable plumbing damage.

Compliance with Australian Standards

All work carried out by Your Choice Plumbers is completed in accordance with the relevant plumbing standards, helping ensure pressure control, hot water delivery, and plumbing component safety are checked properly.

In simple terms, this means the home’s plumbing is not only repaired when something goes wrong, but also assessed for hidden risks that could lead to preventable water damage.
