A drain hose replacement takes 15 to 30 minutes and costs $15 to $50 for the hose itself

You can replace a washing machine drain hose yourself if water is leaking from the back of the machine, the hose is cracked or kinked, or the connection is loose. The job requires no special tools—just a bucket, adjustable wrench, and the new hose. Most people can do this without calling a technician, though you will need to turn off the water supply and pull the machine away from the wall.

The hose connects the pump inside your washer to the standpipe (the vertical drain pipe in your wall) or a sink. Over time, hoses crack from age, kink from being bent too tightly, or develop leaks at the connection points. Replacing it stops water damage and prevents mold growth in the space behind your machine.

Key Takeaways

  • Turn off both the hot and cold water supply valves behind the washer before you start, and unplug the machine from the outlet.
  • The inlet hoses (water in) and outlet hose (water out) are different—buy the correct replacement hose for the drain, which is usually ribbed rubber and larger in diameter.
  • Drain hoses connect with either a slip connection (push-fit) or a threaded connection (screw-on), so check which type yours uses before buying the replacement.
  • After installation, run a test cycle with no clothes to check for leaks at both connection points before pushing the machine back into place.

What you will need before you start

Gather these items before you pull the washer out: an adjustable wrench or slip-joint pliers, a bucket or shallow pan (to catch water still in the hose), a flashlight or headlamp, and the replacement drain hose. You also need to know whether your hose connects with a slip connection (a rubber collar that tightens with a hose clamp) or a threaded connection (a fitting that screws on).

To find the right replacement hose, check your washer's model number on the back or inside the door frame, then search the manufacturer's website or call their parts line. You can also take a photo of the old hose and its connections to a local appliance parts store—they can match it. Drain hoses typically cost between $15 and $50 depending on the brand and length.

How to disconnect the old drain hose

Turn off the water supply by closing both the hot and cold valves behind the washer—they are usually oval knobs on the wall. Unplug the washer from the electrical outlet. If your machine has a power cord you cannot unplug, turn off the circuit breaker for that outlet instead.

Pull the washer away from the wall far enough to see the back. You will see two inlet hoses (usually braided metal, carrying water in) and one outlet hose (the drain, usually ribbed rubber). Place a bucket under the drain hose connection to catch any water still inside it. If the hose connects to a standpipe, you may need to pull it straight out of the pipe opening; if it connects to a sink, it may sit in the sink basin.

Loosen the connection at the pump end (the end attached to the back of the washer). If it is a slip connection, use your wrench to loosen the hose clamp—turn it counterclockwise until it is loose enough to slide off. If it is a threaded connection, use the wrench to turn the fitting counterclockwise. Once loose, pull the hose away from the pump.

Now loosen the connection at the drain end (where the hose meets the standpipe or sink). Use the same method—loosen the clamp or unscrew the fitting. Pull the old hose free and let any remaining water drain into your bucket.

Installing the new drain hose

Before you connect the new hose, check that it is the correct length. Most drain hoses are 4 to 5 feet long, but if your washer sits far from the wall or your standpipe is unusually high, you may need a longer hose. Hold the new hose in place to confirm it reaches both connection points without kinking.

Start at the pump end. If your old hose used a slip connection, slide the hose clamp onto the new hose first, then push the hose onto the pump outlet. Tighten the clamp by turning it clockwise with your wrench until it is snug—do not over-tighten, as this can crack the fitting. If your old hose used a threaded connection, screw the new hose onto the pump outlet by hand first, then use the wrench to tighten it a quarter turn more.

Now connect the drain end. Push or screw the hose onto the standpipe or sink drain using the same method you used at the pump. Make sure the connection is tight enough that water cannot leak out, but not so tight that you crack the fitting. If the hose goes into a standpipe, it should sit inside the opening with a small gap—the gap allows air to enter so water drains freely.

Testing for leaks before you finish

Turn the water supply back on by opening both the hot and cold valves. Plug the washer back in and run a short test cycle—use the rinse-and-spin cycle with no clothes inside. Watch the back of the machine for drips at both connection points. If you see water leaking from a connection, turn off the water and tighten that fitting a little more, then test again.

Let the cycle finish and check the area under the machine for pooled water. If the drain is working correctly, water should flow out smoothly with no leaks. Once you confirm everything is dry, push the washer back into its normal position against the wall.

Common mistakes that cause leaks

The most common error is over-tightening the hose clamp or fitting, which cracks the plastic or rubber and creates a leak that shows up only when water is running. Tighten until snug, then stop—you should not need a wrench to turn it further. Another mistake is using the wrong hose diameter; inlet hoses are narrower than drain hoses, so confirm you have the drain hose before you buy.

A third mistake is pushing the drain hose too far into the standpipe. If the hose sits too deep inside the pipe, it can create a siphon that pulls water out of the machine even when it is not running, leaving puddles on the floor. The hose should sit inside the opening with about an inch of space between the end of the hose and the bottom of the pipe.

Finally, do not reuse the old hose clamps if they are corroded or damaged. New clamps cost a dollar or two and prevent leaks that develop weeks after installation.

When to call a professional instead

If water is leaking from inside the machine rather than from the hose connection, the problem is likely the pump or an internal seal, not the hose. If you cannot reach the hose connections because the machine is wedged too tightly, or if the fitting is cracked and will not hold a new hose, a technician can remove and reinstall the machine or replace the pump. If you are not comfortable working behind the machine or turning off the water supply, a service call costs $150 to $300 but takes the guesswork out of the job.

Frequently Asked Questions

Can I use a regular garden hose as a drain hose?

No. Garden hoses are designed for low pressure (water flowing in), while drain hoses are designed for gravity drainage (water flowing out). A garden hose is also too stiff to fit the connections and will kink easily. Always use a hose made for washing machine drains.

What if the hose connection is stuck and will not turn?

explore a penetrating oil like WD-40 around the fitting and let it sit for 15 minutes, then try again with your wrench. If it still will not budge, wrap a rag around the fitting to protect it and tap gently with a hammer to break the corrosion loose. Do not force it hard enough to crack the plastic.

How often do drain hoses need to be replaced?

A drain hose typically lasts 5 to 10 years depending on water quality and how often the machine runs. If you notice cracks, kinks, or leaks, replace it right away rather than waiting for a failure. Replacing it before it fails prevents water damage to your floor and walls.

Does the hose need to be elevated or can it hang straight down?

The hose can hang down, but it should not loop below the level of the washer tub. If the hose dips too low, standing water can back up into the machine. The ideal setup is a gentle slope downward toward the drain with no sharp kinks or tight bends.
