Learn why your Kelso Tumbler might leak and how to fix it. Simple steps to check the lid, spout, and seal.
Quick Answer
A leaking Kelso Tumbler is usually caused by a loose lid, a blocked or worn spout valve, or a damaged seal. Here's how to diagnose and fix it.
Why Leaks Happen
The Kelso Tumbler is designed with a silicone sipper spout that has a built-in valve to stop water flow when no one is drinking. This makes it great for kids and on-the-go use, but like any valve mechanism, it can get clogged or wear out over time. Leaks can also happen if the lid isn't screwed on correctly or if the seal is damaged.
Diagnosis & Fix Guide
- Symptom: Water leaks from the spout when the tumbler is tipped or shaken.
- Likely Cause: The silicone spout valve is blocked with debris or the lid is not fully tightened.
- Corrective Action: Remove the lid and rinse the spout thoroughly under warm water. Use a soft brush to clean the valve area. Ensure the lid is screwed on tightly before use. If leaking stops, the fix worked.
- When to Stop or Replace: If the spout valve is torn, cracked, or missing, or if the lid seal is damaged, the tumbler may need replacement. The Kelso Tumbler is not designed to be leak-proof with a damaged valve. Replace the tumbler if the valve or seal is broken.
