Why Does My Reverse Osmosis Faucet Gurgle Constantly?

One of the most common complaints about a reverse osmosis faucet is that it gurgles constantly. To be honest, this is not an uncommon problem. The reason behind this particular sound is usually because there are small particles or bumps on the surface of your faucet that cause the water to hit them and make a constant buzzing noise. You can easily fix this by cleaning out those annoying bumps!

What Causes a Reverse Osmosis Faucet to Make Noise?

The number one reason why your faucet may be making noise is because there are particles or bumps on the surface of your faucet. These bumps can either cause the water to hit them and make a constant buzzing sound, or they can just prevent the water from flowing smoothly.

Another reason why your faucet may be making noise is because you’re having issues with the seal at the bottom of your faucet. The seal needs to fit snugly in order for it to work properly, so if it’s loose or if there are particles around it, this could lead to a gurgling sound.

The final reason for this problem is that you may need to replace your filter. If you’ve had your sink for more than five years, it’s likely time to get a new filter. Once you replace it, you’ll notice an immediate change in that annoying gurgling sound!

Here are some possible causes of gurgling:


It’s actually quite easy to get rid of the annoying gurgling sound on your faucet. You can do it with some simple tools and cleaning supplies. First, remove any debris that may be blocking the faucet head by removing the sprayer head and opening up the aerator (the small cone thing). Clean out any clogs or debris that you find inside. Second, use a toothbrush or pipe cleaner to scrub away any built up grime around the water spout. Finally, refill your sink with hot water and repeat until all of the air bubbles are gone. If you still hear noise, repeat these steps until they stop!

Over-sized Membrane

In a reverse osmosis faucet, the membrane is on the inside of the water flow. The water passes through a membrane and is filtered. This process removes any impurities from your drinking water.

If there is a particle or bump on the surface of your faucet, it will cause the water to hit it and make a constant buzzing noise. This can happen because of wear and tear of your faucet or if you have not properly cleaned out your faucet in a while.

The best way to fix this problem is by cleaning out those annoying bumps! You can use some vinegar to loosen up dirt that’s been hiding inside the surface of your faucet for years. Then, use a toothbrush to scrub away any stubborn spots. Finally, clean out any loose particles with a good thorough rinse using hot water and soap before turning it off so they don’t build up again.

High Feed Pressure

A high feed pressure is also a common cause for gurgling. This can be due to too many people in your home or it may be caused by the hot water heater being set too high.

To fix this problem you’ll need to turn down your hot water heater and increase the amount of cold water in your faucet.

Defective Flow Control

The most common complaint is that the faucet constantly makes a gurgling noise. This is because there might be particles or bumps on the surface of your faucet that cause the water to hit them and make a constant buzzing sound.

You can easily fix this by cleaning out those annoying bumps! They’re usually found in places like between the handle and spout, or where the water meets the sink.

Misaligned Drain Pipe

If you’ve ever had a problem with your reverse osmosis faucet gurgling, there’s a good chance the sound is coming from the drain pipe. If your drain pipe is misaligned, it won’t be angled properly for water to flow out of it smoothly. This can cause air to become trapped in the pipes and create that annoying sound.

Luckily, this is an easy fix! Simply pull up your faucet and remove the plumbers putty that’s holding the drain pipe in place. Now, turn the tailpiece counterclockwise until you can see where it connects with the drain pipe. Make sure not to turn too far or you’ll disconnect the entire assembly.

Then, use a pair of needle-nose pliers to reposition the tailpiece so that it points directly down at the bottom of your sink before twisting it back into place with your fingers. Finally, reconnect and tighten all connections by hand and make sure they’re on tight and secure before replacing and putting on your faucet (the water should now stop gurgling!).

How to Fix a Noisy Reverse Osmosis Faucet

The most common cause of a noisy faucet is because of small particles or bumps on the surface of your faucet. The water will make a constant buzzing noise because of the way it’s hitting these small things and making a strange noise.

To fix this problem, you simply need to clean out the surface of your faucet. You can use a sponge or any scrubbing tool that will allow you to get into the crevices of the faucet and get rid of those pesky particles. Once you’ve done that, you should notice an instant decrease in the noise!

There are also other ways to get rid of this problem if cleaning doesn’t work for you. For instance, sometimes all that’s needed is replacing the O-rings inside your faucet, which are what causes that annoying sound. This is an easy fix that anyone can do without having to worry about using tools they don’t know how to use.

How Do I Stop My Reverse Osmosis Gurgling?

You may be surprised to learn that a simple cleaning may stop your water from gurgling. When the water hits the bumps, it causes them to make a noise. So, you can easily fix this problem by removing the bumps from the surface of your faucet.

Here are a few ways you can clean off those bumps:

  1. Use a toothbrush to scrub the bumps.
  2. Use a nail file to gently sand the bumps off.
  3. Use an emery board to sand the bumps off, being careful not to scratch the surface of your faucet in the process.
  4. You can also use sandpaper, but be careful not to remove so much that it damages your sink’s finish in any way.

If you don’t want to remove them all together, you can always try covering them up with stickers or other decorations that are available at craft stores or even on Amazon . Another option is using a special spray on product that is made specifically for this purpose and can be purchased at any hardware store.

You will want to make sure that you clean the bumps off of your faucet at least once a month, as often as possible if you are experiencing any issues with them. It is also recommended that you replace the washers on your faucet every year to prevent any other problems from occurring.

How Can I Make My Air Gap Faucet Quieter?

The first step to making your air gap faucet quieter is to clean off the small bumps or particles on its surface. This will make it less likely for water to hit them and create a constant humming sound.

If you don’t have time or can’t get to those pesky particles, you can purchase a special sleeve that sits over the top of your faucet, which will eliminate the noise.

The other option is to install a valve that comes with a built-in air gap. These come in many stylish finishes and are quiet because they allow the water from the tap to flow into a basin below before it reaches your sink.

However, these valves take up more space than other options so it may not be an option if your kitchen is small or doesn’t have room for one of these types of valves.

RO faucet suction/crackling sounds - "3 MOST Common Causes"


A reverse osmosis system is designed to remove contaminants from your drinking water. A noisy or gurgling faucet indicates that the water is flowing too quickly over the membrane. This can be caused by a number of factors, including too much feed pressure, an oversized membrane, or a defective flow control valve.

To get your faucet back to its quieter state, you can adjust the flow control valve to slow the water flow, install an air gap faucet, or replace your membrane with one of a smaller size.
