Water Filter Keeps Popping Out? Here’s 4 Fixes To Try

Is Your Water Filter Stuck

Water filter keeps popping out? The reason behind might be your water pressure. Here’s 4 fixes to try.

Having water available at all times is a basic human necessity, which is why, being the proud owner of a water filter that can provide the life-giving liquid in a clean, purified way, is a welcome commodity.

The problem is, that when it fails, it turns out to be much more inconvenient than it seems. Sure, you can go back to drinking tap or bottled water, but it will never be the same.

Once you try the good stuff, it’s hard to let go.

This is why I’ve prepared the list below to help you troubleshoot the possible causes behind this occurrence, and find the most convenient solution. The best part is that the majority of these fixes can be done very easily, without taking too much of your time.

Ready? Let’s begin!

Water filters are essential for preserving good health, as they remove unwanted impurities from water such as sediment and bacteria to result in better quality water.

Your Water Filter Keeps Popping Out Due To…

  • High water pressure
  • A botched installation
  • The wrong replacement parts
  • Internal damage

You’d be surprised at how many people experience this issue on a daily basis, only to find the answer to their prayers within arms reach.

While there is always the possibility that your situation could be different, it’s safe to say, that, in 80% of cases, your filter popping conundrum comes from one of the elements on this list. Don’t turn to the tap just yet!

#1 Your Water Pressure Is Too High

Regulate your water pressure

That’s right. Sometimes the problem has nothing to do with your water filter. There’s a very big chance that too much water pressure is the factor to blame when your appliance keeps popping out. How so? Physics.

If your water pressure is too high, the force it carries has nowhere to go, but up. So, when your water filter is not properly positioned, or simply not designed to withstand such forces (most of them aren’t), it pops out and leaves you with a flooded kitchen floor at best.

Moreover, even if your water filter could somehow withstand the pressure, there is also a locking mechanism inside it.

In an ideal scenario, it should always be fully open, but when the water is coming in too strong, it might be staying partially shut. A problem within a problem.

Solution: Try dialing your water pressure back a bit. If you’re unsure as to how you can do this, please do not hesitate to call an expert.

That being said, doing this yourself should not be too complicated. There’s usually a little valve beneath your sink that can regulate how much water passes through. All you have to do is slightly turn it clockwise until the pressure is adequate.

More often than not, you can do this with your bare hands, but in case it proves difficult, having a monkey wrench handy can’t hurt.

This should stop your water filter from popping out.

Depending on your area, your home may be prone to high pressure. Testing water pressure is quick and easy, and all you need is a simple and inexpensive pressure gauge. 

#2 Botched Installation

Hey, we all make mistakes!

There’s a chance that your water filter was installed inadequately by either you, or your technician. This is very common. In fact, I would even go as far as to say it’s probably the most common reason behind a water filter that keeps popping out.

As you can probably imagine, there are parts and mechanisms within your water filter that are responsible for holding it in place and withstanding the incoming water pressure (when it’s not comparable to that of a firefighter’s hose, of course!). When these are not locked in all the way, adhesion is compromised.

Solution: You have two options here.

If you feel confident, you can try and take a look at the attaching mechanisms to figure out how you can securely latch them onto your kitchen surface. It’s usually very simple. Proper positioning and some pressing down should do.

On the other hand, if you feel like that’s too much trouble, you can always call a technician. There are no repairs or spare parts needed, so they should be done in a jiffy.

#3 Wrong Replacement Parts

Your replacement parts might be the wrong size

This will only be your case if you have serviced your water filter recently, or purchased a generic replacement part. Buy cheap, buy twice.

Sadly, most water filter manufacturers build their products in a very specific way, which forces consumers such as yourself to buy their original replacements if they want a properly functioning appliance. I know, it’s frustrating.

There is a very good chance that, if you recently bought a replacement part for your water filter, it could be a couple millimeters too wide, or too thin. Yes, even the slightest differences matter.

Solution: I know I basically said you had to buy your replacements from your manufacturer, but there are some ways around it. That is, if you don’t mind spending some time doing precise measurements.

If possible, take the old part you’re about to replace, and measure it carefully. By doing this, your chances at buying a generic replacement that actually works are increased dramatically.

Alternatively, you can try to use the old part to make space for the new one.

For example, let’s say the problem is that the new part is not opening the locking mechanism properly. You can use the old, original one to hold it open, and then insert the replacement to fit in the way it should.

This is not ideal, but if I can help you save some money, I’m all for it!

#4 There’s Internal Damage

Watch out for “under the hood” damage

Considering this should be your last resort.

As you know, there’s no way to put a broken internal component back together…not if you want it to function properly anyway. If there’s something broken inside your water filter, it could have trouble holding on to your kitchen surface or passing water altogether.

If you have tried all the possible causes above and none of them have worked out, chances are, something snapped inside your appliance.

No matter how precisely you try to pry the locking mechanism open, or check your water pressure, if it’s broken, it’s broken.

Solution: First, you must identify which component is broken. Once you have done that, you can take your water filter and ask for the replacement part you need.

If you feel confident in making the repairs yourself, be my guest. That being said, in this case, it would be wise to let your manufacturer’s technician do the job to protect the new part’s warranty.


Having your water filter keep popping out, leaves you in a very frustrating position.

While it’s not the end of the world, and there are other sources of drinkable water available, once you have tried the purified alternative, going back to anything else is inconvenient, at best.

The good news is that fixing the issues behind this is very simple and DIY-friendly.

More often than not, you won’t even need to buy a replacement, just experiment with your water pressure and make sure everything’s sitting tightly and securely the way it’s supposed to.

Having said that, it’s never a good idea to try and do the repairs yourself when you’re doubtful. Please call a technician if this is the case.

Even if you don’t do it yourself this time, you can still learn from watching the professionals work.
