Bulge in Washing Machine Hose?
What it means: The hose is ready to burst.
A bulging washing machine hose is an emergency. It may burst next year, next week or right now. But it will fail and it won't just leak—it will gush. In just a few minutes, it can do thousands of dollars in damage.
Replace Rubber Hoses with Braided Stainless Steel
What to do: Immediately turn off the valves connected to the hoses. Before your next load of laundry, you'll need to replace the hoses. Buy new baided steel hoses and while you're at the home center, invest in a pressure gauge that hooks onto a spigot or laundry room faucet. Your rubber hoses may have bulged because your water pressure was too high. It shouldn't be more than 80 psi. If it is, install a pressure-reducing valve (PRV) before you damage other appliances and fixtures in your house. If you already have a PRV, it may be set too high or due for replacement.
