When it comes to protecting your home from unexpected water damage, few plumbing components are as overlooked and as critical as the humble flexi hose. These flexible braided pipes are commonly found under sinks, toilets, and washing machines, connecting your water supply to fixtures. While they may seem harmless, a worn-out flexi hose can become a ticking time bomb.
At Jim’s Plumbing, we’ve seen firsthand how a burst flexi hose can cause thousands of dollars in water damage in mere minutes. The good news? Most flexi hose failures are preventable. You just need to know the warning signs.
Below, we break down the 5 Warning Signs Your Flexi Hose Needs Replacing so you can act before disaster strikes.
1. Visible Rust or Corrosion on the Braided Stainless Steel
Flexi hoses are reinforced with a stainless-steel braid that gives them strength and flexibility. However, if you start to notice rust spots, corrosion, or discolouration on the exterior, it’s a clear sign of deterioration.
This damage is usually caused by moisture build-up, chemical cleaners stored nearby, or poor-quality hose material. Once corrosion sets in, the hose becomes brittle and is much more likely to split under pressure.
Tip from Jim’s Plumbing: Check under your sink or behind your toilet once a month. Shine a torch on the hoses and inspect for any rust patches or fraying.
2. Bulging or Ballooning of the Hose
A flexi hose should look smooth and tight. If it appears swollen, bubbled, or ballooned, this is a red flag. Bulging often occurs when the internal rubber tubing begins to fail, usually from age or prolonged water pressure. The outer braided steel may stretch outwards, but it won’t hold forever.
Think of it as a worn-out tyre: one more pressure spike, and it could burst.
Don't ignore this: A flexi hose that’s ballooning is at high risk of failure. Immediate replacement is recommended.
3. Water Leaks or Dampness Nearby
Water pooling under your sink or behind appliances could indicate a slow leak from your flexi hose. Even if it’s not actively dripping, slight dampness, mould, or a musty smell can signal trouble.
A leaking flexi hose might not burst right away, but it will continue to deteriorate, and the longer you wait, the more extensive the damage can become.
Jim’s Insight: Leaks often start small. A proactive replacement now can prevent major headaches (and bills) down the track.
4. Age of the Hose (Over 5 Years Old)
Like anything else in your home, flexi hoses have a lifespan. Most manufacturers recommend replacing them every 5 to 10 years, depending on water quality, usage, and installation.
If your flexi hoses were installed over 5 years ago—and especially if you don’t know their exact age—it’s safest to replace them. Many insurance policies won’t cover water damage caused by old or poorly maintained plumbing components.
Pro tip: During your next routine plumbing check-up, ask Jim’s Plumbing to assess and date your hoses. We’ll record the installation for your peace of mind.
5. Poor Installation or Kinks in the Hose
Improper installation is one of the most common causes of early flexi hose failure. If the hose is stretched too tightly, kinked, twisted, or rubbing against sharp edges, the chances of wear and rupture increase dramatically.
Hoses should always have a gentle loop and not be pulled taut. If you notice sharp bends or friction marks on the braid, it’s time to replace and reposition them properly.
Our advice: Never DIY your flexi hose replacement unless you’re experienced. Jim’s Plumbing can install it safely and ensure full compliance with Australian standards.
Why Flexi Hose Maintenance Matters
Flexi hose bursts are one of the leading causes of internal water damage in Australian homes. These incidents often occur suddenly and can lead to costly repairs, mould growth, damaged cabinetry, and even electrical hazards.
The cost of a professional replacement is a fraction of the cost of fixing flood damage. That’s why Jim’s Plumbing recommends inspecting your hoses regularly and replacing them before they fail.
