The least expensive, and thus the most common (big surprise?) type of clothes washer supply hoses look like these. They are a black rubber material with metal fittings crimped onto the ends. Water leaks happen when the clothes washer hoses age because the black rubber fails. This almost always happens at the point where the rubber meets the end fitting. It is preceded by a visual bulging or bump in the outside of the hose. When it leaks it usually results in a fine, visually imperceptible spray of water that can go a significant distance. What the homeowner sees is water running from the ceiling or a wall a few to several feet away from the washer! Oops. There are two ways to prevent this weird or unusual water leak and thus save damage, stress or an emergency plumbing visit.
1) Inspect your hoses regularly for any unusual visual symptoms. Better yet,
2) Change the hoses to a braided stainless steel exterior. This provides the best burst resistance available. They also have stainless steel fittings. The cheap black rubber hoses have fittings that rust and then fuse onto the shutoff valves. When the hose ends are fused onto the valves you’ll need to replace both the hot and cold shut off valves and hoses at the same time.
New clothes washer hoses can be an inexpensive way to avoid an expensive and stressful water leak surprise. Having the right hoses installed can also make it much easier and convenient when you replace your clothes washer. This is because the appliance delivery people can then connect the new washer saving a plumbing service visit. A top quality hose has a larger diameter increasing flow by almost 50% saving time every time you do laundry.
