The hoses behind your washing machine: the cheap flood-prevention check
In one line: Rubber washer hoses age like tyres, and they burst with the house asleep. The inspection, the upgrade, and the ten-dollar valve habits that protect the floor below.
The two hoses feeding your washing machine are under constant water pressure, every hour of every day - and when one fails, it fails completely. A burst washer hose can release hundreds of litres an hour into a room nobody is standing in, which is why the little valves behind the machine deserve ten minutes of your year.
The inspection (twice a year)
Slide the machine out (unplug it first, and mind the drain hose), then run your fingers along both supply hoses looking for: bulges or ballooning, cracks - especially near the fittings - rust stains at the connections, kinks, and any brittleness. Turn the machine's valves off and on once while you are there; a valve that has not moved in years is often the second failure waiting. Anything soft, swollen or cracked gets replaced this week, not "when there's time" - and make sure you can kill the whole supply if a hose lets go mid-cycle.
The upgrade that ends the worry
Old-style rubber hoses are the failure case. Braided stainless-steel supply hoses are inexpensive, available at any hardware shop, and vastly more resistant to bursting - replacing rubber with braided steel is the single cheapest flood-prevention upgrade in the house. While manufacturers' and insurers' guidance commonly frames rubber hoses as worth replacing within a few years, the honest rule is simpler: inspect often, upgrade to steel once, and stop thinking about it.
The habits that do the rest
Leave a hand's width between machine and wall so hoses don't kink. Shut both valves off if you travel for more than a few weeks - a small ritual that removes the entire risk while you are away. And know the fixture valves' location well enough to show someone else - the machine's other common failure, the no-drain, is a different and cheaper fix.
If the worst has already happened, the sequence matters: valves off, water up with towels and a wet vacuum fast, and the room dried properly - because damp that lingers becomes mould, and the meter test catches the slow leaks this checklist can't see. Ten minutes and the price of two hoses - versus the floor below yours.
