Quick Answer
Most Trek Tumbler leaks come from a misaligned or dirty lid seal. Realign the lid, clean the gasket, and test with water before assuming a defect.
Common Causes of Leaks
Leaks usually start at the lid. The seal may be out of place, the lid not fully closed, or debris caught in the groove. On the Trek Pivot Tumbler, the interchangeable lid pieces can also come loose if not clicked in fully.
Temperature changes can affect pressure inside the tumbler, causing small drips from the lid vent. This is not a defect, but it can look like a leak.
If you've dropped your tumbler, the lid or body may be damaged. Inspect the lid and rim for cracks or warping.
Diagnose and Fix Your Leak
- Symptom: Liquid drips from the lid or around the rim when the tumbler is tipped or carried.
- Likely Cause: The lid is not fully closed, the seal is misaligned or dirty, or the lid pieces on the Trek Pivot are not locked in place. Check that the lid is fully seated and the seal is clean and centered.
- Corrective Action: Wash the lid and seal with warm soapy water, dry them, then reassemble. Ensure the seal sits evenly in the groove. For the Trek Pivot, press the sipping piece until it clicks. Close the lid firmly until you hear or feel it lock. Test with cold water before filling with hot liquid.
- When to Stop or Choose Another Option: If the leak persists after cleaning and realigning, the seal may be worn or the lid damaged. Contact customer support for a replacement part, or consider a new tumbler if the body is cracked. A damaged lid or body cannot be fixed with cleaning alone.
