There is a small, unassuming piece of plumbing sitting under your kitchen sink or bathroom vanity right now that has caused more home flooding in Australia than most people realise. Flexible braided hoses, the short corrugated connectors that link your tap fittings to the water supply, have a limited lifespan and a habit of failing without much warning. When they go, they really go. A burst flexi hose can push out hundreds of litres of water in a very short time, and if you are not home when it happens, the damage can be significant.
The good news is that checking your flexi hoses is something any homeowner in Mildura or the Greater Sunraysia region can do with nothing more than a torch and a few minutes. You do not need to touch the plumbing at all. You are just looking. Here is how to do it properly, with the traps called out along the way.
Step One. Know Where Your Flexi Hoses Are
Before you can check them, you need to find them. Most homes have flexi hoses in the following spots.
- Under every kitchen sink (usually two, one hot and one cold)
- Under every bathroom basin or vanity
- Behind the toilet cistern (connecting the water supply to the cistern inlet)
- Under laundry tubs
- Behind dishwashers and washing machines (though these often use a different hose type)
Open the cupboard doors under your sinks and grab a torch. The flexi hoses are the silver braided tubes, usually 30cm to 45cm long, that run between the tap body above and the isolation valve or water supply pipe below. Toilet flexi hoses are usually shorter and sit behind or beside the cistern at floor level.
The trap here is forgetting one. People often check under the kitchen sink and call it done. Make a habit of checking every wet area in the house. It only takes a few extra minutes.
Step Two. Look at the Condition of the Braid
The outer layer of a flexi hose is a stainless steel braid. That braid is not just cosmetic. It is the structural layer that holds pressure. What you are looking for is any sign that this braid has been compromised.
Run your torch slowly along the full length of each hose and look for.
- Rust or brown staining on the braid itself. Light surface discolouration on the fittings is common, but rust eating into the braid wire is a warning sign.
- Broken or frayed individual wires in the braid. You might see a small loop of wire sticking out. That means the braid is starting to fail from the inside out.
- Ballooning or bubbling anywhere along the hose. If the inner rubber lining is pushing through a gap in the braid, that hose is under serious stress and close to bursting.
- Kinks or sharp bends. Flexi hoses should run in a gentle curve, never a tight angle. A kinked hose puts constant stress on the braid and will fail sooner.
The trap people fall into here is only looking at the middle of the hose. The ends, where the hose meets the fitting, are actually the most vulnerable point. Check right up to both ends carefully. Rust and failure almost always start at or near the connections.
Step Three. Check the Fittings and Connections
While you are down there, check the fittings at each end of the hose. These are the threaded metal nuts that connect to the tap and to the isolation valve or pipe.
What to look for.
- Corrosion or green or white mineral buildup around the nut. Some mineral residue from Sunraysia's hard water is normal, but heavy corrosion on the fitting itself is a concern.
- Any sign of moisture or dampness around the connection. Run your finger along the fitting and check underneath. Even a slow weep here means the seal is failing.
- Cracking in any plastic fittings. Some hoses use plastic ends rather than metal. These age and crack, especially in warm undercupboard environments.
If you find any dampness, do not just wipe it and move on. A weeping connection is telling you something. It is worth having a plumber look at it rather than hoping it stays at a weep.
Step Four. Think About Age
This is the step most people skip entirely because they do not know when their flexi hoses were installed. The general industry guidance is that flexi hoses should be replaced every 10 years regardless of how they look. The inner rubber liner degrades over time from the inside and you cannot always see that from the outside.
If your home is more than 10 years old and the hoses have never been replaced, there is a reasonable chance they are overdue. If you genuinely have no idea how old they are, that is worth flagging when you next have a plumber on site for any job. It takes very little time to swap them out while someone is already under the sink for another reason.
The trap here is assuming that because a hose looks fine it is fine. The inner rubber does not advertise its own deterioration. Age is a real factor even when the outside looks okay.
Step Five. Know When to Step Back and Call a Plumber
Everything above is visual and hands off. You are not turning anything, tightening anything, or disturbing anything. That is exactly the right approach for a homeowner check.
Call a licensed plumber if you find.
- Any moisture, dampness or active dripping at a connection
- Visible rust eating into the braid
- Frayed or broken wires in the braid
- Any ballooning or bubbling on the hose body
- Hoses that are clearly kinked or sharply bent
- Hoses you know are more than 10 years old
Replacing a flexi hose is a straightforward job for a licensed plumber and replacing one proactively is a whole lot cheaper and less stressful than dealing with a flooded bathroom. In a place like Mildura where the summer heat can be brutal, undercupboard temperatures run high and that accelerates the degradation of the inner rubber liner. It is worth being across this one.
A quick check two or three times a year takes about five minutes and a torch. Make it part of your routine alongside checking smoke detector batteries. It is one of those small habits that can genuinely save you a lot of grief.
