You should replace washing machine hoses every 5 years as preventative maintenance.
Replacing the washing machine hoses every 5 years is a good idea to prevent a possible ruptured hose which can cause severe damage to your home.
I always replace my washing machine hoses every 5 years regardless of how good they look as the washing machine hoses are cheaper than the damage they could cause if they rupture.
Some rubber washing machine hoses may only last a few years and some may last longer but after 5 years it's always best to replace the washing machine hoses.
Install a water hammer arrestor, which helps absorb the shock of water that increases pressure within the hose after the washing machine cycle ends.
Turn off the water supply to washing machines when they aren't in use.
Signs that your washing machine supply hoses may be ready to fail include blisters in the hose, worn tubing, stress cracks or a loose connection.
Tighten the connection if it feels loose.
Replace the supply hose if it shows any sign of wear.
The most common site of failure is near the connection where the hose bends.
Standard washing machine hoses are made of black rubber.
Unfortunately some of these hoses only last a few years and will eventually fail, causing one big mess and costly water damage.
