Why Is My Tervis Leaking?
Your Tervis may be leaking for a variety of reasons. The most common reason is due to a damaged or worn-out lid or seal. Make sure the lid and seal are properly in place and try tightening the lid to see if that stops the leak. If the issue persists, there may be a crack or hole in the cup itself. Check the cup for any visible damage and consider replacing it if necessary.
