Why Does My Kitchen Faucet Pulsate?

Having a clean kitchen is a necessity for every home. When our kitchen faucet starts to pulsate, it makes our daily kitchen duties a bit more difficult; it can also get annoying fast. Given the importance of your kitchen faucet, it might make sense to learn to fix this annoying problem.

This blog will help you to find out why does my kitchen faucet pulsate? and give you some solutions for it.

Why Does My Kitchen Faucet Pulsate?

The main reason for pulsating your kitchen faucet is most likely due to water surging. This happens because air pressure in the water tank is low, causing water to fill the tank too much, causing an overflow and then surging that excess water through your tap.

What Causes a Faucet to Pulsate

There are many reasons why a faucet starts making unusual noises when you turn it on. Because there is not enough air going through it, water will be stuck in the pipes. In simple terms, the force behind water pushing through pipelines is caused by air compressing the water. The sudden closing of taps causes air to get trapped inside the pipes.

What to Do If Your Faucet Is Pulsing?

Early Action Is Crucial.

Unfortunately, it’s not uncommon for people to realize too late that there is an issue with their water pipes. The longer a problem goes unaddressed, the more severe it becomes and therefore the more costly it is to fix. It can also badly influence your system.

Check The Air Pressure In The Tank

The most likely problem we’re facing when starting up an air compressor is too much pressure in your tank, so it is vital to check the air pressure. You should switch off the electricity first, then empty the tank and the water pump. 

After that, the bladder value will appear in the water tank. You can use pliers to keep them away and use a tire pump to inflate the bladder so that you can test it with a pressure gauge. 

If the pressure is too high, you can reduce the air in the valve. If it is not high enough, you need to continue pumping.

However, when the pressure is in a suitable range (2PSI lower than your pressure switch), the pressure does not cause any problems.

Examine Your Pressure Switch

You need to check the pressure switch carefully because it can be clogged, corroded for a long time. If you don’t do so, you will take time to detach and arrange them again.

Taking care of it more frequently can save your money to repair or change some old ones. 

Adjust The Pipe That Connects To The Kitchen Faucet

Finally, you need to check the quality of the water pipes in your system. The loose pipe can cause pulsating, so you need to keep it tight.

Seek Professional Assistance

If you try all the above problems and still do not find the cause, you should contact an expert for help. You should not damage some vital or expensive details because it is complex to repair. Some experts in this field can find the problems quickly and correct them for you quickly.

What Makes Water Pressure Rise?

If the amount of air is not enough, water becomes forced into the tank and causes a rise in pressure. Pressure tanks use a design that allows the air and water to mix so that the excess water slowly evaporates. If the bladder becomes punctured or torn while relieving pressure, all of the contents will empty suddenly.

What Causes My Water Pressure To Vary So Much?

The reason why water pressure fluctuates has multiple contributing factors. Here are a few of the most common sources: air trapped in the pipes, clogged and outdated lines, failed pressure-reducing valves, varying water input, crowded water supply lines, and so on.

What Can I Do If My Water Pressure Drops?

When stopping pressure decreases in water, it’s crucial to first figure out what’s causing them.

  • Keep track of the air pressure of the water tank.
  • Change the balancing valve into the thermostatic to avoid mixing cold and hot water.
  • Take into consideration some high-pressure devices and calculate the time to use
  • Make sure the diverters are new.
  • Check to see if the water lines are clogged and when the busiest times are.
  • Check your water supply frequently.
  • Keep track of the pipe’s leaks.

How Can You Make a Kitchen Faucet Flow More?

Unclog The Aerator

It’s important to keep your kitchen faucet clean and to work properly. To do this, you simply have to add an aerator to your faucet with proper instructions. 

If the aerator becomes blocked with dirt, remove it and soak it in warm water with vinegar combination for a few hours to release the caked-on filth.

Unclog The Cartridge

Cartridges can get blocked by dirt. This prevents the flow of water from reaching your nozzle. Therefore, you should detach it from the tap first and then wash it thoroughly. 

If this doesn’t work after a few tries, it’s best to soak it in vinegar for a few hours and try again. If it fails, you should replace it with a new one.

The main reason for pulsating the kitchen faucets is the rise in water. If you do not find the real cause for this problem, you can contact a professional. They are always ready to help. 

How Do I Get The Air Out Of My Kitchen Faucet?

How Do I Get The Air Out Of My Kitchen Faucet

Here are some quick tips to get the air out of the kitchen faucet:

  • Open up all the water faucets throughout your home at once
  • Repeat step 1 on all the hot and cold faucets.

This helps flush out any sediment that may have built up over time. And this also clears airlocks which can occur when switching from hot to cold temperatures or vice versa.

How Do You Fix Water Hammer?

You will need to use air chambers to repair your old plumbing system. It is a short pipe located immediately behind a valve assembly. It acts as a shock absorber to dampen the water’s impact when the flow is completely stopped.

Air chambers sometimes get their protectiveness nullified by water that has been pressed into them over time. You need to close your home’s main valves and turn on faucets at the highest and lowest installations of your home. When the rest of your plumbing drains, the now well-fitted chambers will form with air automatically, reopening your main valves as you check for noise or problems.

You may want to consider installing air chambers or water hammer arrestors if you aren’t already using them to mitigate the effects of water hammers. Air chambers are sealed devices that do not require maintenance over time, whereas arrestors may need replacing in the years to come.


As you can see, there are many reasons why you might be experiencing a pulsating kitchen faucet. The good news is, with a little bit of knowledge, you can easily fix this problem yourself. We hope this article has helped you determine why does my kitchen faucet pulsate? and how to fix it.
