Invest that money in new washing machine hoses and you'll be taking an important step toward avoiding costly damage, mess, inconvenience, and the loss of items that could never be replaced. It's money well spent. To reduce the chances that your hoses will fail, it's a good idea to inspect your washing machine hoses regularly and to take steps to minimize the factors that can cause damage.
Many people can, although some find it preferable to have it done by a professional.
In many cases, it's as easy as hooking up a hose to a water spigot. If you are not comfortable doing this yourself or there is a problem such as the hose will not unscrew easily, then a professional plumber can be hired to do this work. If there's not a shutoff near your washer, close the main shutoff valve in your house. Unscrew the old hoses. Hook up the new hoses.
