Reasons Why Your Nakii Water Filter Pitcher Is Leaking


The Nakii water filter pitcher is an effective filtering system that fits nicely on your counter or in your fridge, except for when it’s leaking.

A Nakii water filter pitcher leaks because of a damaged or loos O-ring, incomplete seal, overfilling or cracks or breaks in the pitcher body. Most of these are easy to fix, but any cracks in your pitcher will mean you need a new one. A brand new Nakii pitcher and filter have also been known to leak from a manufacturing fault in the filter stopping it from fitting the housing area properly.

This troubleshooting guide will show you why your Nakii water filter pitcher is leaking, and how to fix it so you can get back to drinking, and enjoying, filtered water.

Reasons Why Your Nakii Water Filter Pitcher is Leaking

There are only a few reasons why a Nakii water filter pitcher leaks. Here’s how to you can tell why your Nakii pitcher is leaking, what to do about it, and how to prevent future leaks.

If your water filter pitcher has turned green, or has some green residue in it then read this article here to fix it.

1. Damaged O-Ring

The O-ring is a small band of flexible material that helps create a watertight seal between the lid and the body of the pitcher. It looks a lot like a rubber band. The O-ring stops water from leaking out of the filter, or around the filter, and helps make sure that it can filter water properly.

How to detect a faulty O-ring

The O-ring can easily be damaged – it can become loose with time, or develop cracks. A good O-ring should sit snugly within its groove. If it looks slack or loose, it’s almost useless as it won’t provide a proper seal. While this problem isn’t so common, it’s almost guaranteed to happen if you have your pitcher for a long time.

How to fix

  • Check for the O-ring running around the inner side of the lid. 
  • Look to see if it is slack, loose or cracked or if any part of it has shifted out of place. 
  • If it has shifted out of place, push it back in until it’s smugly fitted into its place. 
  • If it’s loose you will need to buy a replacement as they can’t be fixed.

To prevent future damage to the O-ring, avoid touching it as much as possible and always be gentle with it. It’s also best to avoid using harsh detergents or other chemicals to clean your pitcher’s lid.

2. Incomplete Seal

With Nakii water filters, a proper seal is needed for it to filter water properly and to not leak. The pitcher’s components, including the filter itself and the housing, must be correctly installed to create a secure seal. This seal makes sure that water passes through the filtration system without leaking out.

If there are gaps during filter installation water will leak out and around the filter, which also means the water won’t be filtered. This can also happen if the replacement filter is a generic (non-Nakii) filter, or is the wrong size and doesn’t fit in properly.

There have also been instances where a brand new filter and Nakii water filter pitcher leak. This is usually because of a fault in the filter from manufacturing resulting in it not fitting the filter housing properly. In this case water will leak directly around the filter and not be filtered. You will need to contact customer support for a replacement filter to fix this problem.

How to Detect Improper Seal or Installation

If water leaks out of the pitcher as you try to pour yourself a cup of water, or you can see the water leaking around the filter into the bottom of the pitcher, your pitcher may have a sealing problem. Each part of the pitcher, including the lid and filter housing, have sealing mechanisms to prevent leakage. For these to work, everything needs to fit in properly.

How to fix

  • Take apart the parts of the water filter pitcher and lay them on a clean surface
  • Use a mild soap and water solution to clean all the components, paying attention to the O-rings on the lid and filter housing. Rinse everything properly under a running faucet. This helps to remove any residues or debris that can prevent proper sealage. 
  • With clean hands, put all the components back together according to the manufacturer’s instructions. Make sure everything is properly aligned and correctly seated and refill your pitcher.
  • Also, when it’s time to replace the filter, make sure you get the right Nakii Aquelen filter size.

How to prevent an improper seal

All the components of the Nakii filter pitcher are made to fit properly into each other. Here’s how you can prevent future problems with leaks due to improper installation.

  • Minimize how often you take off the lid or take apart the pitcher. The pitcher’s lid has an opening for easy and convenient refills. This means you don’t need to remove the lid every time you want to refill. The less you open the lid, the less your chances are of having an improper reinstallation. Also, the more often you take the pitcher’s components apart, the more dirt and debris find their way in which can compromise the integrity of your seal.
  • When you need to replace the filter or take the pitcher apart for any reason, clean the components with mild soap and running water before putting them back together again. 

3. Overfilling

Overfilling the Nakii pitcher is one of the most common reasons for it to leak. You may not think you are overfilling your pitcher, but even filling the reservoir to the top can cause your pitcher to leak.

How to Know You’ve Overfilled Your Pitcher

The Nakii pitcher doesn’t have a clear-cut indicator of how much water is too much. If your pitcher stops leaking after the water level has gone down, then it was likely leaking because it was overfilled in the first place.

How To Fix

To prevent overfilling your Nakii pitcher, leave at least an inch of space after a refill before closing the lid.

4. Breaks or Cracks

The Nakii water filter pitcher has three major external components: The slide open lid, the handle, and the transparent body. 

If there is a break or crack in the body or the lid of the filter pitcher, water can leak out. When this happens to the body of the pitcher, water will leak out of the pitcher and form water stains or pools of water on surfaces.

How To Fix

Check over the body of the pitcher for any cracks or visible damage. You may need to hold it up to the light to see any hairline fractures in the plastic. If there is any, unfortunately you will need to get a replacement pitcher.
