Washer supply hose maintenance checklist
Updated August 2026
Replace washer supply hoses every 5 years, whether or not they look worn, and give them a yearly look for bulges, blisters, rust, or kinks. Fit braided stainless, not bare rubber, and shut the hot and cold valves whenever you leave town for more than a day. A washer hose sits under full house pressure every second, and when one ruptures it can spill hundreds of gallons an hour, one of the most common and costly home water claims.

What neglect costs
Here is the math that makes this the easiest win in the house. A pair of braided stainless hoses costs about $10–20 each and takes twenty minutes to fit. The failure they prevent, a rubber hose that splits or blows off the valve, runs at house pressure with nobody home, and washing-machine hose failures are repeatedly ranked a top source of household water-damage claims. The typical resulting bill lands at $5,000–10,000 once you count soaked drywall, flooring, and everything below a second-floor laundry. Twenty dollars against ten thousand is not a close call.
Leave these to a pro
The swap itself is a DIY wrench job, but call a plumber when the shutoff valves behind the washer are corroded, seized, or weep when you turn them, since a valve that will not close makes hose replacement risky; replacing a pair runs about $150–300. It is also worth hiring one to install a recessed washer box with a single-lever shutoff, or a leak-sensing auto-shutoff ($30–100 for the device), which cuts the water the instant it detects a drip. Any of these is trivial next to the flood it heads off.

Are braided stainless hoses really burst-proof?
More burst-resistant, not indestructible. The stainless braid protects the rubber tube inside from blowing out and resists the pinhole splits that doom bare rubber, which is why it is the standard upgrade. But the inner liner still ages and the crimped end fittings can corrode, so braided hoses are not a fit-and-forget part. Keep the 5-year replacement schedule anyway, and inspect them yearly. If you ever see a bulge, a rust bloom at the coupling, or dampness, replace both immediately rather than waiting for the calendar.
Should I shut the washer valves after every load?
In a perfect world, yes, but almost nobody does, and reaching behind the machine each time gets old fast. The practical answer is to always shut them for trips of a day or more, and to make daily use painless by installing a single-lever valve that closes both hot and cold with one motion. If your valves are the stiff old two-handle type, a plumber can swap them while adding a proper washer box. The point is simply that a closed valve cannot flood.
How do I replace a washer supply hose myself?
It takes about twenty minutes and a pair of pliers. Shut the hot and cold valves, then run the washer on a rinse for a few seconds to drop the pressure. Unscrew the old hoses at both the valve and the machine, keeping a towel and bucket handy for drip. Check that a rubber washer sits in each new braided hose end, hand-thread the couplings straight to avoid cross-threading, then snug them a quarter turn past hand-tight with pliers. Reopen the valves and watch every joint for a full minute.
What is the difference between a fill hose and the drain hose?
They fail very differently. The two fill or supply hoses carry pressurized hot and cold water into the machine, so a failure there sprays continuously, which is the flood this checklist guards against. The single drain hose only carries used water out by gravity and pumping, so a problem there is usually a slow leak or a backup, not a gusher. Both deserve a yearly glance, but the pressurized fill hoses are the ones on a hard 5-year replacement clock.
