Why Every Sydney Landlord Should Check Their Flexi Hoses Before It’s Too Late

At Moshav Realty, we regularly see avoidable maintenance issues turn into major and expensive property damage. One of the most overlooked risks in residential properties across Sydney is something many landlords and tenants never think about — flexi hoses.

These small plumbing components are commonly installed throughout kitchens, bathrooms, laundries and behind toilets, quietly doing their job every day. However, when they fail, the damage can be significant.

What Are Flexi Hoses?

Flexi hoses are flexible rubber water pipes encased in a braided stainless steel outer layer. They connect water supply points to taps, toilets, dishwashers, washing machines and other plumbing fixtures.

They became widely used in Australia approximately 25 years ago as a replacement for rigid copper pipe connections because they offer several advantages:

Faster and easier installation
Greater flexibility in tight spaces
Reduced stress on plumbing connections
Ability to absorb movement and pressure changes

While convenient, they do not last forever.

Why Flexi Hoses Fail

Most flexi hose failures happen because of one of the following:

1. Age and Deterioration
Most manufacturers recommend replacement every 5 to 10 years. Over time, the internal rubber lining can weaken and deteriorate.

2. Poor Quality Materials
Low-quality or non-certified hoses are far more vulnerable to corrosion and premature failure.

3. Incorrect Installation
Improper installation by unqualified contractors can cause hoses to kink, twist or place excessive stress on connection points.

4. Exposure to Household Chemicals
Cleaning products stored under sinks can accelerate corrosion and damage the outer stainless steel braid.

5. Lack of Regular Inspection
Many homeowners and landlords simply forget these hoses exist until they burst.

The Cost of a Burst Flexi Hose

A failed flexi hose can release up to 1,500 litres of water per hour.

In some cases, enough water can escape within 24 hours to cause catastrophic damage, including:

Flooded timber flooring
Ceiling collapse in multi-level apartments
Damaged cabinetry and kitchen joinery
Electrical hazards
Insurance claims and excess payments
Temporary displacement of tenants
Damage to neighbouring apartments in strata buildings

For landlords, this can quickly become an expensive repair bill and potentially lead to rental income loss.

7 Ways Landlords Can Prevent Flexi Hose Failures

At Moshav Realty, preventative maintenance is one of the key ways we help protect our clients’ investment properties.

Here are our recommendations:

1. Inspect Hoses Regularly

Check all visible flexi hoses whenever conducting inspections or reviewing utility bills.

2. Install Isolation Valves

Ensure every flexi hose has an accessible isolation tap so water can be shut off immediately if a leak occurs.

3. Replace Every 5–10 Years

Do not wait for visible failure. Preventative replacement is far cheaper than emergency repairs.

4. Use Watermarked Certified Products

Only install plumbing products approved for Australian use and compliant with industry standards.

5. Always Use Licensed Plumbers

Incorrect installation remains one of the leading causes of early hose failure.

6. Keep Chemicals Away

Avoid storing bleach, cleaning products and harsh chemicals under sinks near plumbing connections.

7. Ensure Cupboard Ventilation

Poor ventilation can cause condensation build-up which may accelerate corrosion over time.
