Last Updated on May 19, 2023 by River Tree Farms

Before connecting two dishwasher hoses, you need to know a few things. First, the two hoses should be of the same size. Another thing is that the two hoses should be clean. Also, if they are of different sizes, you will need an adapter of the right size.

Here is a quick guide on how to connect 2 dishwasher hoses together. Position the open ends of the hoses such that they are flush with each other. If the two hoses have different diameters, connect the end of one hose to one side of the adapter. Fix the other hose on the remaining side of the adapter. Ensure the connection is tight.

Can You Connect 2 Dishwasher Drain Hoses Together

Yes. It is possible to connect two dishwasher drain hoses together. However, you need to check whether the two hoses have the same diameter. Connecting in such a case becomes easier since you will only need a hose clamp. Hoses of the same size can also guarantee a tight connection.

The problem occurs when the two drain hoses are not the same size. Here, you will require a dishwasher drain hose adapter to connect. Take note that adapters come in different sizes, meaning you need to know the size of your hoses and choose one that fits. An expert plumber can help you choose the right adapter size.

Instead of an adapter, you can also use a hose coupling to connect the two hoses together. A hose clamp is another awesome piece that can connect two hoses of different sizes. Also, remember that some hoses can be of different materials, say, PVC and rubber. In such a case, you will need a rubber coupling to connect the two hoses together.

As mentioned earlier, you need to check whether the two pieces of hose are of the same size before connecting them. For easy connection, you will require the following tools and materials: –

  • Screwdrivers
  • Utility knife
  • Drain hose
  • Drain adapter if needed
  • Hose clamp
  • Hose coupling if needed
  • Drain hose kit


Step 1: Gather the two pieces of hose and examine their sizes. They should be of the same size to achieve a tight connection.

Step 2: Get a dishwasher drain hose adapter if the two pieces of hose are of different sizes.

Step 3: Clean the two hoses to remove any dirt or debris.

Step 4: Fix the open ends of the two hoses together and fasten the connection using a hose clamp. You can also use a dishwasher drain hose clamp to tighten the joint.

Step 5: If the two pieces of hose are not the same size, fix one end of one hose on one end of the adapter. Connect the other hose to the remaining end of the adapter. Please ensure that the connections are tight by fastening them using a hose clamp.

Step 6: Once everything is in place, turn on the water supply and run a dishwasher test cycle to check for leaks. A loose connection or damaged hoses can cause leakage. In case of such, you may have to create proper drainage by redoing the connection or replacing the hoses altogether.

Frequently Asked Questions

What should I do if my drain pipe is not long enough?

A short drain hose can affect the whole performance of your dishwasher. It will not remove the dirty water efficiently. The good news is that you can extend it to your desired length. To do this, look for a flexible hose compatible with your dishwasher’s current drain hose.

You can find it in a drain hose extension kit with a 3ft dishwasher drain hose extension. Connect the dishwasher hose extension with the drain hose and check for any leaks. If you need help doing this, a qualified plumber or service technician can come through for you.

Can I splice a leaking hose?

It depends on the severity of the leakage. If the leakage is major, replacing the drain hose is best. However, for a minor leakage, a simple splice should be able to solve the problem. To splice a leaking pipe, cut a rubber hose big enough to cover the holes. Align the rubber piece on the damaged part and poke holes in each end. Pass a flexible wire through the holes and tie it around the main pipe to secure the rubber piece—test for leakages.


By now, you likely know how to connect two dishwasher hoses together. You need the right tools, which include a screwdriver and utility knife. Essential components include hose coupling, adapter, and hose clamp, depending on the type and size of the hoses. To connect two drain hoses, align the ends so they are flush with each other.

Use a clamp or coupling to fasten the two hoses together and test for leakage. If the drain hoses are of different sizes, use an adapter to fix them together. This process doesn’t involve much. Even so, you can still seek help from a professional service technician if you find it difficult to do.
