So, if you have low pressure in your kitchen faucet, you have to work out where actually the problem is coming out. Is this problem only in your house? Or this problem throughout your house? Or this problem is in your whole neighborhood?

So, the first thing in this situation is to check other water outlets throughout your house. After checking if you have other fixtures low water pressure and not only just the kitchen faucet then it is likely that is a problem to your whole building and if it’s not then it’s only in your kitchen.

If it only affects your whole house, you should also ask your neighbors that they are suffering from this type of similar problem. So if your neighbors also have this type of issue with this low water pressure, then the problem lies with the municipal main water supply. So, you need to contact the authorities and have to deal with this problem.

If you have a problem with low water pressure then there are a lot of ways to get rid of this problem that you can do things.

First, you can try checking the pressure of the water that comes into your house from the mainline – and try to check also when the valve is fully open. There is also another possibility that is the main valve where the whole water enters your house is probably old and that needs replacing. If so, then contact a plumber that can fix or do that work by yourself.


If this type of problem isn’t the problem, then you should also check in your plumbing system if there are any leaks. Leaks can cause the water pressure in your whole house to drop, and for this leaking water can also cause some serious damage. That means you have to identify if there is any possibility for leaks as soon as possible and finally fix the leaks.

Here’s how to check and fix these types of problems.

Blocked Aerator

The aerator fits into this type of the end of the faucet. Its specialty is that it acts as a restrictor which is used to knock off the water flow by adding air. It’s a specialty that has many small holes in it which become clogged with mineral deposits and sediment over time. It is the easiest and most likely way to resolve the water pressure problem.

  1. Remove the aerator from the faucet. Try unscrewing it by hand. This can be surprisingly difficult. You may need to resort to a pair of pliers. Place the plastic tape on the gripping surfaces so that they don’t scratch the metal, or alternatively use a cloth to protect the metal.
  2. If you are unable to remove the aerator, you may have to try to remove any clogging with the aerator still in place. So you can pour vinegar into a plastic bag and tie around the end of the faucet for several hours. This should help to dissolve some of the debris that is causing the problem.
  3. If you get the aerator off, you can soak it in a dish of vinegar and warm water for several hours. After this, if it is still blocked then you can try to use a commercial lime remover to clean it. Failing this you can replace the aerator. They are not very expensive.
  4. While the aerator is off, run your faucet to determine whether you have found the cause of the problem. If the pressure is still low after the aerator is removed the problem must be further down the waterway, and you may have to employ the services of a plumber.
  5. After you have cleared the aerator, rinse it out and screw it back again. Check the water pressure. If you have cleared the mineral deposits and sediments from the aerator your water pressure should be restored.

Another technique you can use is to fill a plastic baggie with vinegar and water with a ratio of 1:1. Fasten the baggie over the faucet head with a rubber band so the faucet head is immersed in vinegar and leave it overnight. This should help dissolve any mineral build-up.

Check the Cartridge

If the problem isn’t the aerator, it may be the cartridge. Here’s how to check and fix this issue – or for a preview, here’s a video with a very clear explanation for how to change a faucet cartridge.

  6. Finally place the cleaned. And replace all the important parts that you have to remove and then you can check water pressure.

Impaired Pressure Reducing Valve

Impaired Pressure Reducing Valve

Some homes are equipped with something called a “pressure reducing valve.” This device regulates the pressure coming from the municipal water supply into your home. It is relatively very easy to locate; look for a bell-shaped device that is sitting on the incoming water line.

If the water pressure is low, you can adjust it by loosening the screw sitting at the top. Turn it counter-clockwise and open the tap again to check for improvements. If it’s still too low, the valve might be worn out — we recommend calling a plumber to check.

Water Line Breaks

Water Line Breaks

It’s very offensive that breaks in your water lines can occur from time to time. And it is very difficult to detect them. A break into your water line is very easy if it’s not only your kitchen sink that has lost the pressure of water.

You can confirm if there is a break somewhere in your water lines by taking the meter reading. For this close all the faucets and also water outlets and now take the meter reading. About four hours take again another reading of the meter. There is also a change in the readings that would be a significant leak caused by a break in the water lines somewhere.

When only the hot water pressure is low

If it is only the hot water pressure that is low, you should check the water heater. The hot water shutoff valve may be faulty or partially closed. If it is even slightly shut it can have an enormous impact on the water pressure.

Once properly closed, check your water pressure again. If the pressure is still not good the problem may lie with the pipework to the heater or with the heater itself. It is hazardous to work with water heaters so it is now time to call the plumber. Plumbers have diagnostic tools that they can use to locate blockages and leaks in pipes.
