Introdução

A leaky water key can make playing difficult and a horn sound strange. Instrument repair professionals can fix leaky water keys, but often times all a water key needs is a new cork—an easy fix you can do at home. Water key corks are inexpensive and available at most music stores and online, but a wine cork cut to the right size will work in a pinch.

  1. Obtain a replacement water key cork. If you’re in a rush and don’t have a replacement cork, you can make a temporary one out of a wine bottle cork.

    • Your cork slice should now have four marks equidistant from the center mark.

    • Draw a circle connecting the four marks around the center.

  10. Using your knife, cut out this circle. It helps to slice edges off at angles, one at a time. This might take a few tries, so if you end up with a non-round circle cut out, repeat Steps 3-9 with the remaining wine cork.

    • If your cork is too big, you'll need to cut it a little smaller.

    • If your cork is a little uneven, don't worry. Its job is to seal the water hole, which is much smaller than the cork itself.

  12. With a hot glue gun, put a drop of glue in the water key slot and place the new cork on top. Press firmly on the cork for a few seconds.

If your water key still leaks after replacing the cork, it may need to be bent back into place or may need a new spring. See an instrument repair professional or another online guide for help with this.

Let me suggest that there is an easier way to a permanent solution for leaky corks - remove the water automatically by installing a JoyKey. No more leaking corks, no moving parts, no sptings or having to manually deal with water.
