Why Does My Kitchen Faucet Pulsate

Are you frustrated with your kitchen faucet pulsating? You’re not alone! This is a common issue that many homeowners experience, and it can be pretty annoying.

But don’t worry – we’ve got you covered. In this article, we’ll explain why your kitchen faucet is pulsating and how you can fix it quickly and easily. We’ll also provide some tips on how to prevent it from happening in the future.

So if you’re ready to take control of your kitchen faucet and keep it working smoothly, read on!

Causes Of Faucet Pulsation

One common factor that can lead to this issue is low air pressure in the water tank. When the air pressure is insufficient, it can cause the water to flow in a pulsating manner as it comes out of the faucet.

Another possible cause is a clogged aerator. When debris builds up in the aerator, it can cause the water to flow unevenly and create a pulsating effect.

Trapped air within the water system is yet another factor that can contribute to a pulsating faucet. This can happen when air becomes trapped in the pipes, which can occur during repairs or when the water supply is turned off.

Pressure surges can also lead to a pulsating faucet. When the water flow suddenly stops, it can create a surge of pressure that causes the water to pulse as it comes out of the faucet.

Other potential causes of a pulsating kitchen faucet include leaky supply lines or faucets, excessively hot water, or metal components in the sink and water pipes that expand and contract due to temperature changes.

If a plumber installed the faucet, they may not have used PEX tubing, which can also contribute to a pulsating faucet.

How To Fix a pulsating kitchen faucet

Checking The Faucet For Blockages

First, check the spout for any blockages or obstructions that could be causing the pulsation. Make sure nothing is stuck in the aerator or clogging up the small holes in the nozzle head.

The water pressure should be even when flowing from all sides of the spout; if not, this could be an indication of a blockage somewhere.

Next, use a flashlight to look inside the pipes behind the faucet for any leaks or cracks that could also be causing pulsating water flow.

If you see damp patches or dripping around any joints then these are signs of a leak which needs repairing as soon as possible to stop further damage occurring.

Ensure all washers, seals and fittings are tightly secured and free from corrosion before turning on your tap again to test if this has solved your problem.

Adjusting The Water Pressure

If there are no visible issues with your pipes, then it might be time to take a closer look at your water pressure regulator. This device helps regulate the amount of water flowing through your pipes and can help prevent excessive pressure from damaging them.

To check if yours is working properly, try testing it with a pressure gauge and adjusting the settings accordingly. If this doesn’t fix the problem, you may need to call a professional for assistance.

Sometimes pulsating from a kitchen faucet can be caused by something as simple as a worn-out washer inside the faucet head itself – so don’t forget to inspect that as well!

Testing each component separately can help you pinpoint exactly what’s causing the issue and give you an idea of how to address it quickly and effectively.

With some careful troubleshooting and maintenance, you should have your kitchen faucet running smoothly in no time!

Replacing The Diverter Valve

The first step is to assess the damage and determine whether or not you need to replace the valve.

If it’s clear that it needs replacing, then there are a few simple steps you can take to do it yourself.

First, turn off the water supply and disconnect the supply line. Once this is done, use an adjustable wrench to remove the existing valve.

Then use a pair of pliers to remove any remaining pieces from the old valve. Finally, install the new diverter valve and make sure it’s securely tightened in place.

Now that your new valve is installed, reconnect the supply line and turn on the water supply.

Test out your faucet to make sure everything is working properly – no more pulsating. With a little bit of effort, you’ve fixed your faucet quickly and easily.

Cleaning The Aerator

Cleaning the aerator is an essential part of maintaining a healthy kitchen faucet. It’s a simple process that requires very little in terms of time or resources, yet can dramatically reduce pulsation.

Installing filters and regularly checking for leaking pipes are also key to avoiding pulsating water flow.

To begin, shut off the water supply to the faucet and remove the aerator from the end of the spout. Then, using a pair of pliers, unscrew any debris that has built up on the aerator screen and rinse it thoroughly with warm water.

Once this is done, reassemble your aerator and reinstall it onto your faucet.

This simple process can help keep your kitchen faucet free of pulsation by ensuring that it’s clear of any debris or blockages. By regularly cleaning your aerator and installing filters to catch dirt particles before they enter your pipes, you can keep your kitchen faucet in peak condition for years to come.

Installing A Pressure Regulator

Installing a pressure regulator is another way to help solve your pulsating faucet problem. A pressure regulator will help keep the water pressure balanced throughout your home, and reduce any malfunctions caused by too much pressure in certain areas.

It’s an easy task that requires no special tools and can be done quickly—just make sure you get one that’s suited for outdoor use if necessary.


It’s such a coincidence that so many of us have experienced the same problem with our kitchen faucets – pulsation.

It can be incredibly annoying and even confusing to figure out why it’s happening, but now we know how to fix it!

By checking for blockages, adjusting the water pressure, replacing the diverter valve, cleaning the aerator and installing a pressure regulator, you can get your kitchen faucet back up and running smooth.

Now I won’t have to deal with these pesky little pulses any more – I’m sure you won’t either!

With this newfound knowledge, let’s all take advantage of it and keep our kitchen faucets in perfect working order.

We all deserve that peace of mind that comes with a functioning kitchen faucet.
