A:Answer You can use the old hoses, change the washer,,,, But remember that they will be there for 10 plus years,, Why take a chance.. Then again if they are almost new as you said,,,, One thing to remember is that Hoses do wear out. I have rentals and over the years several have sprung a leak, none have burst.. one was the new metal covered type. Most important is to be sure to level your washer, and not let them get too out of balance. One thing i do is put the sound reducing rubber pads under the feet.
