Flexible braided hoses — often called flexi hoses — are a common sight in modern homes. You’ll usually find them under sinks, basins, and connected to toilets. They’re the small stainless-steel braided hoses that connect your taps and fixtures to the water supply.
They may look tough, but flexi hoses are one of the most common causes of plumbing emergencies and water damage in Australian homes. In fact, many insurance companies list burst flexi hoses as one of the top reasons for water damage claims. Some insurers are now even requesting reports on the condition of flexi hoses before renewing policies.
Why Flexi Hoses Fail
Flexi hoses don’t last forever. Over time, the stainless-steel braiding can weaken and the rubber inner tube can deteriorate. Common warning signs that your hose may be close to failing include:
- Rust or discolouration on the stainless-steel braid
- Fraying or loose wires in the braid
- Bulging or blistering sections of the hose
- Leaks or damp patches underneath sinks or near toilets
If you notice any of these, it’s time to act before disaster strikes.
The Cost of a Burst Flexi Hose
When a flexi hose bursts, it can release hundreds of litres of water per hour. If it happens while you’re out or asleep, the damage can be catastrophic — soaking carpets, swelling cabinetry, damaging plaster, and even affecting electrical systems.
Repairs can run into tens of thousands of dollars, and while insurance may cover the damage, it’s still a stressful, time-consuming process that no homeowner wants to go through.
How to Protect Your Home
The good news? Burst flexi hoses are completely preventable with regular checks and timely replacement.
- Inspect regularly: Look under your sinks, basins, and toilets for any signs of rust, fraying, or bulging.
- Replace every 5–10 years (we recommend every 5): Even if your flexi hoses look fine, it’s best to replace them before their lifespan is up.
- Call a licensed plumber: DIY replacement isn’t recommended. A qualified plumber can install new hoses safely and ensure they’re compliant.

Flexi Hose FAQs
How often should I replace a flexi hose?
Flexi hoses generally last between 5–10 years, but we recommend replacing them every 5 years for peace of mind. You should still be making regular visual inspections during this time.
What are the signs a flexi hose is about to burst?
Look for rust, fraying, bulging, or damp spots under sinks and around toilets. Any of these could mean your hose is close to failing.
Will my insurance cover damage from a burst flexi hose?
Some insurance policies will cover water damage, but many are now asking for proof that flexi hoses have been checked or replaced regularly before they renew your policy. Prevention is always cheaper and less stressful than repairs.
Can I replace a flexi hose myself?
It’s not recommended. A licensed plumber can ensure the hose is fitted correctly and meets Australian standards. Incorrect DIY installation can lead to leaks or void insurance claims.
Where should I check for flexi hoses in my home?
Flexi hoses are most commonly found under sinks, basins, toilets, and sometimes behind dishwashers or washing machines.
