How do you cap off a dishwasher drain line?

There are a few different ways to cap off a dishwasher drain line. One way is to use a T-fitting. Another way is to use a plastic fitting with a rubber gasket. Still another way is to use plumber’s putty.

Which method you choose will depend on the type of pipe you are using and the type of fitting you have available.

If you are using a T-fitting, simply screw the T-fitting onto the end of the dishwasher drain line. If you are using a plastic fitting, push the fitting onto the end of the pipe and then tighten the clamp around it. For both of these methods, you will need to attach a hose to the other side of the T-fitting or plastic fitting.

If you are using plumber’s putty, push the putty onto the end of the pipe and then screw on a cap. Be sure to wipe off any excess putty that squeezes out from under the cap.

Once you have capped off the dishwasher drain line, you can remove the garbage disposal.
