Easy Steps on How to Shorten Dishwasher Drain Hose

In day-to-day use, the dishwasher hose tends to stretch over time. If it is too long, you might struggle to find a suitable location for it in your kitchen. Luckily, you can shorten the dishwasher hose quite easily and quickly using the following steps:

Step 01: Turn Off the Water Supply to the Dishwasher

First, shut down the water supply to your dishwasher. You can do this by turning off the hot and cold valves beneath your sink. Doing this will prevent water from leaking out while the hose is disconnected.

Step 02: Drain the Remaining Water from the Hose

Now you should drain all remaining water from inside the hose so that there is absolutely nothing in it when you cut it. To do this, plug one end of the hose with your thumb or another object that can block the flow.

The other end should be connected to the dishwasher drain pipe. Then, open both valves to allow water to stream out through your sink’s drain hole.

Now all the remaining water has been drained from inside the hose.

Step 03: Now Measure the Hose

You should now take the time to measure your dishwasher hose before cutting it down to size. This is important as you must make sure all parts are cut down to the same size for a perfect fit.

Using your tape measure, determine how much you need to shorten the hose by, and then mark that length on both sides using your marker.

Step 04: Cut the Hose to the Desired Length

Now you can cut your dishwasher’s drain hose to the desired length using either an adjustable wrench or a large pair of scissors if you don’t have one on hand.

Once both sides are clipped at the same length, you should immediately test them out together with your dishwasher before securing the fittings in place.

Step 05: Clean the Hose before Securing It in Place

Once you’ve cut down your dishwasher’s hoses to the desired length, then it is time to clean them up with some soap and water. Be sure that both ends are entirely free of rust, dirt, or grime before inserting them into the fittings on either end.

Step 06: Reconnect the Dishwasher Drain Hose

You can now finish the job by reconnecting the dishwasher drain hose with your sink’s plumbing. You can do this by inserting both ends into their respective fittings, twisting them clockwise to secure them in place, and then turning on the main water supply.

Once you’re done, run a test cycle on your dishwasher to ensure it is working correctly.

That’s all there is to know about how to shorten the dishwasher drain hose that was too long for your kitchen space. Your dishwasher drain hose should now be short enough and ready for use.

See, it isn’t too difficult to shorten the dishwasher’s drain hose when needed. You can do this easily with a little bit of elbow grease and some simple tools that you probably already have around your home.
