Avoiding an appliance water supply hose failure
November 6, 2015
If there is one thing that is easy to overlook it is checking the water supply hoses of washing machines and dishwashers.
Hidden away behind the machine, they are often the last things on the mind of the ever-busy householder.
But these rubber hoses can eventually deteriorate and burst without warning.
A burst rubber hose can easily release up to 2200 litres of water an hour.
Left undetected, often when the house is empty during the day or when the occupants are sleeping at night, that’s an awful lot of water to clear up. It is also likely to cause catastrophic and expensive water damage to the structure and fabric of the house.
Yet changing the hoses on these appliances is a relatively simple procedure.
Replacement hoses are readily available from most DIY stores.
First turn off the electricity supply to your machine and either isolate the water supply where it connects to the hoses or turn off the entire water supply at the mains. Modern appliances only have the one cold water supply hose. If your appliance has a hot water supply hose as well, usually indicated by a red coloured pipe and fitting, you may need to drain down your hot water supply tank if you are unable to isolate it locally.
Now pull the appliance away from the wall carefully to access the hoses. Bear in mind that there will also be a drainage connection at the rear of the appliance, so take care not to damage it. In some circumstances you may need to disconnect this drainage connection.
Now simply remove the old hoses and replace with the new ones, ensuring that they are securely fastened. It is a good idea to place an old towel beneath the old hoses as you remove them to catch any water left in them.
The appliance can then be returned to its original position and the water and power restored.
It is a good idea to inspect appliance hoses at least every two years to check for signs of damage and deterioration.
It is recommended that hoses are replaced at least every five years, regardless of their condition.
For added peace of mind, it is possible to purchase specialized fittings which monitor water pressure and cut off the supply if a change in pressure indicates a leak.
