Flexible braided hoses, commonly called flexi hoses, are found in almost every modern home. You’ll usually find them under sinks and basins, behind toilets and connected to various plumbing fixtures and appliances. They may be small, but a failed or burst flexi hose can release a significant amount of water into your home very quickly.
With a quick visual check and regular replacement, you can reduce the risk of an unexpected leak and the water damage that can come with it.
What is a flexi hose?
A flexi hose is a flexible water connection that connects a tap, toilet cistern or other plumbing fixture to the water supply.
They typically have a rubber inner tube surrounded by a stainless-steel braided exterior. The flexible design makes them useful where a rigid pipe connection isn’t practical.
You’ll commonly find flexi hoses:
- Under kitchen sinks
- Under bathroom basins
- Connected to toilet cisterns
- Around laundry plumbing
- Behind some appliances and fixtures
Why do flexi hoses fail?
Flexi hoses don’t last forever. Over time, the hose and fittings can deteriorate, particularly if the hose has been incorrectly installed, kinked, twisted or placed under strain. Age and general wear can also affect the hose.
When checking your flexi hoses, look for:
- Rust or corrosion on the stainless-steel braid
- Fraying or broken wires
- Bulging or swelling
- Kinks or twisting
- Cracking or deterioration
- Dampness or signs of leaking around the hose or fittings
If you notice any of these signs, it’s worth having the hose checked and replaced.
How long do flexi hoses last?
There isn’t one replacement date that applies to every flexi hose. Lifespan can vary depending on the product, installation and conditions. As a general guide, flexi hoses are commonly considered to last around 5–10 years.
At H2Pro, we recommend replacing flexi hoses every 5 years as a preventative plumbing measure.
That doesn’t mean a five-year-old hose is automatically about to fail. It’s simply a sensible point to have your flexi hoses inspected and consider replacing them before they become an unexpected problem. Regular visual checks are still important, even if your flexi hoses are less than five years old.
What happens when a flexi hose bursts?
A burst flexi hose can release a large amount of water very quickly. If it happens while you’re asleep or away from home, the water can continue flowing until someone notices and turns off the supply.
Depending on where the hose is located, the resulting water can damage:
- Kitchen and bathroom cabinetry
- Flooring and carpets
- Walls and plaster
- Furniture and other contents
- Electrical components and appliances
Australian insurance research has highlighted the potential impact of burst flexi hoses. CHOICE reported that, according to Suncorp data, burst flexi hoses accounted for 10% of home insurance water-damage claims in 2024, with average claims of around $30,000. That’s why spending a few minutes checking the flexi hoses around your home can be worthwhile.
How to check your flexi hoses
You don’t need to be a plumber to have a quick look.
Every six months, take a look underneath your sinks and basins and around your toilets.
Check for rust or corrosion
Look closely at the stainless-steel braided section. Any visible corrosion is worth investigating.
Look for fraying
Check the braid for broken, loose or damaged wires.
Look for bulging
A hose that looks swollen, distorted or different from the others should be checked.
Check for kinks or twisting
Flexi hoses shouldn’t be excessively bent, twisted or under strain.
Look for leaks or dampness
Check around the hose and its connections for moisture, water marks or signs of previous leaking. If something doesn’t look right, don’t wait for it to get worse.
How to reduce the risk of a burst flexi hose
A few simple maintenance steps can help reduce the risk of an unexpected failure:
Inspect them regularly
Have a look under your sinks, basins and around toilets at least twice a year.
Replace older flexi hoses
H2Pro recommends replacing flexi hoses every 5 years as a preventative measure.
Don’t ignore warning signs
Rust, fraying, bulging or dampness should be checked rather than left until there’s a problem.
Have them professionally replaced
A licensed plumber can make sure the correct hose is used and installed properly.
What should you do if a flexi hose bursts?
If a flexi hose suddenly bursts, the first priority is to turn off the water supply.
If you can safely access the isolation valve for the affected fixture, turn it off. If you can’t, turn off the main water supply to your property.
Then contact a licensed plumber to inspect the hose and connection and replace it where required.
If your home has suffered water damage, contact your insurer and follow their instructions. Insurance cover varies between policies, so check your Product Disclosure Statement rather than assuming a particular type of damage will or won’t be covered.
Should I replace my flexi hoses?
If your home has older flexi hoses, or you don’t know when they were installed, it’s worth having them checked. At H2Pro, we recommend replacing flexi hoses every 5 years as part of our PlumbCare preventative plumbing maintenance. It’s a relatively small plumbing job, but replacing ageing flexi hoses can help reduce the risk of an unexpected water leak and the damage that can follow.
