About Low Pressure Kitchen Faucet

Low Pressure Kitchen Faucet

A low pressure kitchen faucet is a kitchen faucet that has a lower water pressure than normal. This is because the low pressure design helps to conserve water by eliminating waste and helping to conserve water.

Low water pressure is good for saving water. In fact, it is estimated that up to 20% savings in household water can be achieved by installing low flow fixtures such as low pressure kitchen faucets.

This means 20% less money spent on utility bills and a positive impact on the environment. Some of the most popular brands that are known for their low flow products are Delta Faucet, Kohler, Moen, American Standard, and Glacier Bay.

Low pressure is good for smaller households where there are no children or adults with long hair who shower regularly over kitchen sinks. Lower water pressure can also be good for households where people use low flow toilets and low flow showerheads, but don’t want to sacrifice water pressure in the kitchen.

The only negative to a low pressure kitchen faucet is the water pressure. If the water pressure is too low it may make filling pots, cooking vegetables, or rinsing dishes more difficult.

The water flow may not be powerful enough to clear the sink and will require more hand scrubbing. Another downside is that if you like power washing your driveway or home, a low pressure kitchen faucet won’t give you that extra boost to remove stubborn dirt or grime.

Factors Affecting Kitchen Faucet Pressure

Low Pressure Kitchen Faucet

The water pressure in your home is determined by the size of the pipes between your house’s pipe and the city water supply. The water pressure is also affected by how far away the city water supply is from the house.

If you live in a sprawling suburb where you’re more than three miles away from your city’s water supply, then you likely have lower-pressured water coming into your house.

The causes of low pressure kitchen faucets are often due to a buildup of minerals inside the pipes, which could cause the water to have a sluggish flow. There are some other causes that include damaged or disconnected water supply lines, faulty shut-off valves, or an inadequate supply of hot water in the home.

Regardless of whether or not there are significant changes in regulations that can affect pressure, not all faucets will reduce their pressure. Factors that may cause these faucets to remain at a high-pressure level include:

1) The appliance has a high-output design, which means it requires more energy to deliver high water flow rates.

2) The faucet is designed to provide higher pressure for safety reasons, such as in households with children or adults with long hair who shower regularly over kitchen sinks.

3) The household demands a lot of water (for example, because there are many people using the kitchen sink at the same time), which causes a higher water pressure.

4) The faucet is designed to provide higher pressure for water conservation reasons, such as households with people who use low flow toilets and showerheads but don’t want to sacrifice kitchen sink pressure.

5) The faucet is older and its design prevents it from conserving water or reducing pressure.

6) The water heater is unable to provide enough hot water (which can cause the faucet to maintain high pressure, as it needs more energy to increase water flow).

7) The faucet has a booster pump that increases pressure.

8.) A leak in the household pipes or appliances is causing constant and significant loss of water.

If the pressure in your house is too high, then it can damage the internal components of your kitchen faucet such as washers and seals. These replacement parts may also need to be replaced more frequently if you’re using a lower-pressure water supply.

Way To Fix Low Pressure Kitchen Faucet

Low Pressure Kitchen Faucet

Check the shower cartridge

– In a shower, there is a cartridge that regulates the pressure of water. The cartridge consists of a rubber washer and stem assembly so it has to be removed for repair.

– Turn off the shutoff valve in your home’s piping system.

– Unscrew the handle from the faucet base or wall. Take off the screw holding the handle in place.

– Remove any washers, O-rings, or packing material that’s around the cartridge inside the faucet. Save them for later use.

– Use pliers to grab and remove the stem assembly from its seat in the faucet body. If your cartridge is corroded or damaged, it’ll be stuck.

– If the stem assembly is hard to remove, soak it in commercial solvent or use a tool such as a center punch so you can push down on the stem and extract the cartridge once the solvent has softened it.

Disconnect The Water Supply Line

A low pressure kitchen faucet can be caused by dirt or mineral deposits that may accumulate in the lines. One way to fix this is to use pliers, to disconnect the water supply line, which is typically located on the back of the faucet.

Once you’ve disconnected the line you should be able to easily remove any debris that’s present in the female coupling on the other end of it. You’ll want to make sure that there are no adapters installed before reconnecting to ensure a tight seal.

Next, you’ll want to turn your household water back on while there’s still air in the faucet tubing. This should allow for air bubbles that may have been trapped to move through and force out any other particles that were blocking the flow. If this process doesn’t work you can repeat it but use a faucet-cleaning tool instead of pliers.

Check Your Thermostat

In case your problem is with hot water, make sure to check your thermostat before making any repairs. It may be necessary to replace a faulty unit in order to fully fix the problem. If this process doesn’t work, there is a possibility that you may have to replace the tubing in your kitchen faucet.

Replace faucet seat washer

– It’s likely that your washer needs replacing if the stems are rusted or corroded. Gently remove it with pliers.

– Put in a new washer of the same type, if you’re unable to find the exact replacement at the store, check your owner’s manual for more detailed information about your faucet.

– Screw back in the cartridge and put everything back together. Turn on the valve and check for leaks.

Clean or replace faucet aerator

– Your water pressure is low because you have a clogged-up aerator, which helps to increase the flow of water from your tap to provide sufficient water pressure.

– Remove the screw under the handle and take off the top of the faucet, this will expose the aerator.

– Unscrew and remove the aerator from underneath by lifting it up and turning counterclockwise.

– Put a paper towel or rag around your faucet to protect the surrounding surface area. Turn on your tap at a low pressure setting and spray water into the rag to clear out any debris blocking the aerator.

– Replace it back onto your faucet, making sure to use pliers if it’s hard to remove. Turn on your water again and check for changes in tap pressure.

Replacing the faucet

Lastly, if all else fails to fix your water pressure issue in your kitchen sink, you may need to replace the faucet with a new one that has a better flow rate and pressure to address low tap water pressure issues.

Step 1: Shut off the Main Water Supply

– Shut off the main water supply to your house. This is easy to find, especially if you have a gas line that runs into your home.

– Turn on each tap in your house one at a time until you can’t shut them off anymore. At this point, you should be able to tell which one is the main water supply.

– Mark this spot with a piece of chalk, because you will need to turn it back on after you finish your faucet replacement project.

Step 2: Remove the Old Faucet

– Once you’ve shut off the water supply, go underneath your sink and locate the old faucet.

– There should be a water supply line that is attached to the faucet with a coupling nut. Remove this coupling nut using channel lock pliers and then carefully unwind the water supply line from the old faucet.

Step 3: Install New Faucet

– Once you remove the coupling on your existing faucet, you’ll need to slide the new faucet base through the opening of your countertop.

– You should see threads for a coupling nut at the bottom of the faucet, so you can just match it up with your water supply line and hand tighten it until secure.

– After that, turn on the main water supply line and check for leaks.

– Once you have no more leaks, use your channel lock pliers to tighten the coupling nut on the bottom of the faucet base for a secure seal.

Step 4: Test your water pressure

– Once you’ve completed a thorough cleaning, reassembled everything, and tightened all the connections, turn on the water supply again to test for leaks.

– Run each tap in your house to check that there are no more leaks underneath or around your new faucet.

– Finally, you can turn off your main water supply again.

Tips To Fix Low Pressure Kitchen Faucet

Fixing the faucet is not too difficult. You’ll be happy to know that it doesn’t require you to call a plumber every time your kitchen’s water pressure slips down. Below are some of the common causes of low water pressure and how you can fix them:

Low Pressure Kitchen Faucet

1) Dirty Aerator – The aerator filters out impurities in the water while allowing air bubbles to escape. If it becomes clogged with dirt, debris, or sediment, it will reduce water flow. To clean this part, unscrew the aerator and scrub it with an old toothbrush or purchase an inexpensive replacement aerator at your local hardware store. Make sure to tighten the aerator back on securely when you’re done.

2) Hose Bib – The hose bib can also reduce your water pressure if it is leaking. A hose bib should have a screw to tighten it in place, but sometimes these screws get loose and start to drip. To fix it, turn off the water to the kitchen faucet and replace the washers or reseal the bib. If the hose bib is old and rusty, better replace it with a new one.

3) Clogged Aerator – A clog in the aerator is another cause of reduced water pressure. You can fix this by snaking out or unscrewing the aerator and cleaning it with an old toothbrush or replacing the aerator entirely.

4) Loose Handle – The handle might need tightening if it feels loose while you’re trying to turn the water on or off. To tighten the faucet handle, remove the screw located underneath the handle and replace it with a new one. You can also refer to your owner’s manual for help with this step.

5) Dirty Filter – Some models of kitchen faucets have a built-in filter that can get clogged with dirt and debris, causing reduced water flow. To clean the filter, simply twist it counterclockwise and soak it in vinegar overnight. Rinse thoroughly before using again.

6) Moen Shower Cartridge – Water pressure with Moen Faucets is controlled by a specific type of cartridge which can wear out after several years. If your water pressure is still low, even after cleaning or replacing the aerator, removing the handle, or tightening it, chances are you need to replace the Moen shower cartridge.

7) Wrong Water Temperature – Check your hot water temperature. If it is too hot, you may have to reduce the temperature setting on your water heater.

8) Clogged Drain Lines – Water pressure problems can also be due to clogged drain lines. Clear the line closest to your hot water heater first, followed by the ones furthest away.

Low Pressure Kitchen Faucet

9) Air in Pipes – You may experience low water pressure if air gets into your pipes. To solve this problem, switch off the main shut-off valve in your home and open all the faucets in your house.

Turn the main shut-off back on once this clears any air out of the pipes. You can check to see if there are air bubbles coming from your showerheads, laundry machine, dishwasher, or washing machine by holding a tissue close to these fixtures while they are running.

10) Common Issues – Different brands of faucets have their own features, designs, and quirks that can affect water pressure. For example, Delta kitchen faucets usually have low water pressure because they are designed to conserve water than provide good flow rates.

A new Delta aerator with 50% more holes helps increase the flow of water. A new Moen single-handle kitchen faucet usually comes with a separate sprayer hose. The aerator on the sprayer is usually a bit larger which increases water pressure, while the aerator on the main faucet has smaller holes to conserve water.

11) Incorrectly Installed – It can happen that an incorrectly installed hose bib or faucet is the reason behind low pressure. If this has happened, hire a plumber to diagnose and correct the problem as soon as possible.

12) Pressure Is Too Low – If none of the above steps solves your problem, there may be a leak somewhere in the waterline. Contact a plumber to find out where it is and how much it will cost to fix.

13) Water Filter – Be sure to check if the reason for low pressure is also because of your water filter. Unscrew the filter and remove it. Clean it with water under pressure or replace it. If this doesn’t solve your problem, contact a plumber to inspect the condition of all components in your pipes system.    


What causes low pressure kitchen faucet?

The low water pressure in kitchen faucets is caused by a variety of things. Low water pressure may be due to the age of the faucet, wear and tear on parts of the faucet, or it could be due to a leaking washer. There are also some other problems that can cause your kitchen faucet to have low water pressure such as a calcium buildup.

Does a low pressure kitchen faucet work on well water?

Yes, as long as it is filtered and not full of sediment. When using low-pressure kitchen faucet to filter large debris before running the water through the system, be aware that the sprayer head on some designs may clog more easily. You will need to replace it with a washer and contact point (usually available at your local hardware store) for normal use after each time you clean out the pipe with a snake.

Do you need a separate sprayer for the sink when installing a low pressure kitchen faucet?

No, you don’t need a separate sprayer. low-pressure kitchen faucets (also called touchless kitchen faucets) use pressure reduction technology to dispense water with very little effort. You can also install a pull-out or pull-down sprayer for your sink instead of the traditional spray head.

How often do you need to replace the gaskets on a low pressure kitchen faucet?

You would have to contact the manufacturer if you wanted an answer for that. We recommend you replace the seals and gaskets on a low-pressure kitchen faucet every 3-5 years to maintain optimum function.

Do low pressure kitchen faucets always come with a pause button?

No, not all touchless kitchen faucets come with a pause button. If you’re looking for a touchless kitchen faucet, be sure to read the product information carefully to see if it has this feature.

Can I install my own Low Pressure Kitchen Faucet myself or should I hire someone to do it for me?

If you’re looking to install a low-pressure kitchen faucet yourself, you will need a bit of plumbing knowledge and a few tools. To bring your new low-pressure kitchen faucet up to code, you will also need to get a plumber’s approval before installing it. For help with installation, we recommend talking to the store where you purchased the low-pressure kitchen faucet for assistance.


Fixing your low pressure kitchen faucet is not as difficult as it may seem. The most common cause of a faucet that doesn’t produce enough pressure is sediment. To fix this, you can use a wrench to unscrew the aerator from your kitchen sink and then remove any buildup with vinegar or boiling water.
