Flexi Hoses: One of the Leading Causes of Internal Flooding
Flexible braided hoses are commonly found under sinks, behind toilets, and behind appliances. These small plumbing components are one of the most common causes of sudden internal flooding in Australian homes.
Because flexi hoses operate under constant pressure and are exposed to heat and vibration, they can fail without warning.
The Five-Year Replacement Rule
Most flexi hoses should be replaced approximately every five years — even if they appear undamaged. Many Queensland homes still have hoses well beyond their recommended lifespan.
Where to Check Flexi Hoses
- Under kitchen sinks
- Under bathroom basins
- Behind toilets
- Behind washing machines
- Under laundry tubs
- Fridge water connections
Proactive replacement reduces the risk of water damage, insurance disputes, and emergency plumbing callouts.
Added Protection: Isolation Valves
Isolation valves allow individual fixtures to be shut off quickly without turning off water to the entire home. If a hose fails, the affected fixture can be isolated within seconds, significantly limiting water damage and reducing repair costs.
