Flexible water hoses – commonly known as flexi hoses – are found under sinks, behind toilets, vanities, dishwashers, fridges, and hot water systems in most modern homes. While they’re convenient and widely used, they are also one of the most common causes of sudden household water damage when left unchecked.

A failed flexi hose can burst without warning, releasing large volumes of water into your home within minutes and causing significant damage to flooring, cabinetry, walls, and personal belongings.

Why Flexi Hoses Fail

Flexi hoses are not designed to last forever. Over time, the internal rubber lining and external braided layer deteriorate due to:

• Constant water pressure
• Heat exposure
• Age and wear
• Poor installation
• Corrosion or moisture build-up
• Twisting or kinking of the hose

Because deterioration often happens internally, a hose can appear completely fine on the outside right up until failure occurs.

Recent Client Incident

We recently attended a property where a burst flexi hose caused extensive flooding while the homeowners were away. By the time the leak was discovered, water had spread throughout multiple rooms, damaging flooring, cabinetry, and walls.

What started as a relatively inexpensive plumbing component resulted in a costly insurance claim and major disruption for the homeowner.

Unfortunately, situations like this are becoming increasingly common.

Expected Lifespan

Most flexi hoses should be inspected regularly and typically replaced every 5-10 years depending on:

• Brand and quality
• Water pressure
• Exposure to heat and moisture
• Installation environment
• Frequency of use

If you’re unsure how old your hoses are, it’s worth having them checked as part of routine preventative maintenance.

Key Warning Signs – Replace Immediately

If you notice any of the following, we strongly recommend replacement:

• Rust or corrosion around fittings
• Fraying or damaged braided steel
• Bulging or swelling in the hose
• Kinks or twisting
• Water staining or moisture around connections
• Visible leaks or dripping
• Hoses older than 5-10 years

Additional Risk Factors

Certain homes and properties may face increased risk, including:

• Older homes with ageing plumbing
• Properties left vacant for long periods
• High water pressure systems
• Poor quality or unbranded hoses
• Areas exposed to direct sunlight or excessive heat
• Hoses installed in tight spaces causing tension or bending

Why Preventative Replacement Matters

Replacing flexi hoses before failure is a simple and cost-effective way to reduce the risk of major water damage.

A routine inspection can help identify ageing or high-risk hoses before they become a problem – providing peace of mind and potentially saving thousands in repair costs.
