Check the rubber hoses on the back of your washing machine. Are they ten years or older? If so, replace them. If you do not they could burst and cause a flood that goes on and on until someone notices and turns the tap off. The best hoses to get are braided stainless steel hoses. Many come with a warranty to never burst for the life of your appliance. Look for a high “PSI” (Pounds Per Square Inch) rating. You can find one with a 2500 PSI burst strength. This is well above the household pressure, which ranges from 30-70 PSI.
