How To Increase Water Pressure In Kitchen Sink?

If you discover that the low water pressure only occurs in the kitchen sink faucet, it is very likely caused by a blocked aerator or cartridge.

Knowing how to resolve the issue will help you increase water pressure in kitchen sink.

How To Increase Water Pressure In Kitchen Sink?

If the water pressure is low in other locations, the latter four reasons are more likely to resolve. 

1. Clogged Aerator

A faucet aerator is a mechanism that controls the flow velocity of the faucet and is usually situated around the top of the faucet. Mineral particles and detritus can typically clog the aerator. If this is the case, your kitchen sink may gradually lose water pressure. Most of the time, cleaning the aerator will restore the water pressure.

Remove the aerator by hand rotating it anticlockwise. If opening it by hand is difficult, use a set of sliding joint pliers with tape wrapped around the teeth for a firmer grip.

After removing the aerator, immerse it in vinegar and brush out the sediment. In most cases, soaking the aerator overnight is adequate. To summarize, if the particles are too resistant to fall off, they can be replaced at any time.

2. A Faucet Cartridge That Has Become Clogged

Low water pressure in the sink might also be caused by a clogged faucet cartridge. The cartridge regulates the flow of water from the faucet. In other words, by twisting the handle, the cartridge opens the valve and allows water to flow. Cleaning the cartridge is obviously more difficult than cleaning the aerator.

Before beginning to disassemble the faucet, close the shut-off valve to allow all of the water to drain, ensuring that there is no leftover water in the pipeline. Then, close the sink plug to prevent debris from going down the drain. Pry off the handle cover with a flat-bladed screwdriver.

After removing the handle, remove the fastening nut with a pair of sliding joint pliers. This will aid in sticking tape around the pliers’ teeth to improve grip. It can also keep the tap from getting scratched. Then, with a pair of regular pliers, pull the retaining clip down. Finally, the ink cartridge will be accessible through the opening.

3. Water Line Ruptures

The waterline in the faucet may occasionally break. However, checking it out may not be so simple. If your kitchen sink loses water pressure, the water line is likely to be broken as well.

Check your waterline for interruptions by reading the meter. Close all faucets and outlets, then take a meter reading. Read the meter again after roughly four hours.

The shift in the reading suggests that a water pipe somewhere collapsed, resulting in a leak. It is recommended that you contact a professional plumber if you suspect a break in your water lines.

Is The Issue Localised Or Widespread?

 Kitchen Sink?

The first step in resolving the low water pressure issue in the kitchen faucet is to determine the scope of the problem. Other outlets in your home may be affected by low water pressure.

The power with which water flows through your plumbing system is referred to as water pressure. It varies during the day depending on how much water is required.

Low water pressure can have an impact on the entire house. You should inquire with your neighbors to see whether they are experiencing the same issue. The issue could be with the municipal supply.

If this is the case, and you are unable to live with it, you may need to invest in a water booster. This will boost the pressure in your outlets. If your neighbors are happy with their water pressure, the fault is not with them.

What is the reason for the low water pressure in kitchen faucets?

 There are several methods for determining whether your kitchen faucet or all of the taps in your home have low water pressure. Examine each faucet in your home. If they all have the same pressure, the municipality’s pipeline may be an issue. You can also seek confirmation from your local municipality.

If cold water flows at the correct pressure from the faucet but hot water pressure lowers, the problem is with the water heater. The faucet works flawlessly.

Is it possible for a plumber to fix low water pressure?

Most major water problems, such as low water pressure in your home, should be handled by a professional plumbing firm. If you have issues with subterranean pipes and fixtures that only the utility company has access to, you will be unable to make repairs on your own.


Water pressure issues can be aggravating, but they are usually simple to resolve. If the problem is in the municipal water system, the fix may take a little longer, but it should not require much from you other than alerting the proper authorities.

The only high-risk issue is a leaking pipe. If this is the reason for your kitchen sink’s low water pressure, a leak in the incorrect spot might have severe consequences for your entire home.

In that way, seeing decreasing water pressure might be a blessing in disguise, as it is the symptom that alerts you to a larger issue. In any other scenario, the issue should be milder and easier to resolve.
