Removing Gooseneck Pipes from Bathroom Sinks

Gooseneck pipes are common fixtures in bathroom sinks as well as other parts of the home. A gooseneck pipe contains a full 180-degree curve and is designed in order to prevent water from overflowing into areas that it's not meant to go and from flowing in reverse back to the surface of the sink. Occasionally, however, gooseneck pipes do not function as they are intended. In these cases, or if you are conducting a general remodelling of your bathroom or sink fixtures, it may be necessary to temporarily or permanently remove the gooseneck pipe from your sink drainage line. This is a relatively simple procedure that can be done at home without professional assistance.

Step 1—Gather Your Materials

Before beginning to adjust your sink piping in any way, collect the proper materials to complete the job. Ensure that you have the following tools before continuing:

  • Replacement piping or gooseneck pipe of the same size (these often come in pre-set kits that include all necessary screws and other fasteners)
  • Adjustable pliers
  • Teflon tape

Step 2—Shut Off the Water to the Sink

After you've gathered your necessary tools for the removal process, the crucial next step is to disconnect the water supply to your bathroom sink. As with any plumbing job, it is important that you ensure that no water will be flowing through the pipes that you will be working with. Most bathroom sinks have a manual shut-off valve that you can twist by hand. It may be necessary in some cases, however, to shut off water to the entire home or building. Failure to properly shut off the water can lead to flooding, water damage and other complications.

Step 3—Unfasten the Gooseneck Pipe

Adjust your pliers so that they match the size of the screws or nuts that connect the gooseneck pipe to the adjoining pieces of pipe. Ensure that the pliers are not too tight, as this may damage the connecting pieces.

Gently loosen the nuts that attach the gooseneck pipe to the remaining pieces of your sink drainage system. You may find it easiest to begin loosening the nuts with the pliers and then to continue unscrewing them by hand. Adjust the nuts evenly so as to maintain constant pressure during the entire process.

Having removed the nuts, the gooseneck pipe should be free to remove from the adjoining pipe pieces. Carefully lift the pipe out of the drainage area without scraping it against other pipes or any additional surfaces.

Step 4—Replace the Pipe

Before attempting to operate your sink again, and before turning the water supply back on, it is necessary that you replace the pipe underneath the sink in order to complete the line out to the water drain. You may either fit the existing gooseneck pipe back into place, or you may set up the drainage system with a new connecting pipe. In the latter case, ensure that the new piping is the proper size and fit before connecting, and follow all manufacturer or installation instructions before operating your bathroom sink.
