My ZeroWater pitcher is leaking — what should I do?Updated 2 months ago
The most common cause: a loose filter
The vast majority of leaking pitchers are caused by a filter that hasn't been fully tightened into the upper reservoir. Before anything else, try this:
- Empty the upper reservoir completely.
- Remove the filter by turning it counter-clockwise.
- Reinsert the filter and turn clockwise until snug, then give it one firm quarter-turn more.
- Refill the reservoir and check for leaks before placing it back on the pitcher.
Other common causes
- Cracked reservoir or pitcher body: Inspect the upper reservoir and the pitcher body for hairline cracks, especially around the base of the reservoir and along the spout. Cracks can result from dropping or dishwasher heat.
- Damaged filter seal: Check the rubber O-ring or gasket around the filter neck. If it's torn, missing, or deformed, the filter won't seal properly. Contact our customer service team for further assistance.
- Overfilling: The upper reservoir should not be filled above the maximum fill line. Overfilling forces water past the lid seal.
Leaking from the spout
If the pitcher leaks from the spout when tilted, this is usually normal — the lid may not be seated perfectly flat. Make sure the lid is pressed down evenly on all sides.
Still leaking?
