Troubleshooting a plumbing issue can seem like a daunting task. Thankfully, if you notice no water in the kitchen but everywhere else, you can eliminate larger-scale issues like water main leaks.
The most common reasons for only one faucet to stop working (resulting in no water only in the kitchen) is a leak in the pipes leading up to the tap or a blockage somewhere within the pipes. Another potential issue could be that there is a faulty water valve.

Make sure to check all potential causes of no water or low water pressure.
Leak in a Pipe
Sometimes pipes can wear out or rust. Look underneath your sink and run your hands along the entirety of the pipe. If you can feel the moisture, that means there is a leak, and it is reducing the water pressure from your faucet.
It could be a faulty seal in a pipe joint or a spot that has rusted through in older pipes. Depending on the piece, it may be easily replaced, but if you’re in doubt, you should call a local plumbing company.
A common cause for blockage further down a waterline is sediment buildup. It can also be a sign of heavy metal or calcium deposits. If this is the case, you may need a plumber to perform a cleaning on your pipe systems.
A blockage can also occur on the faucet’s aerator, which is the small screen filter at the end of the faucet. Checking the aerator for sediment or other types of buildup can give you an idea if you have an issue further down in your plumbing line.
Faulty Water Valve
At the base of the faucet near where it meets the counter is something called a cartridge. This holds the water valve that allows water to flow freely. This can also acquire buildup, especially if you have hard water. I’ll discuss how to check and fix this a little bit.
Water Heater Issues
Sometimes you may notice that only the cold water is working and that even though the water pressure is fine, there is no hot water. This signifies a water heater issue. It could be blocked with sediment or broken altogether.
Unfortunately, water heater issues can be tricky to fix on your own, and they can also be expensive. Consult with an expert before you begin to tinker around with your water heater.
Although it will most likely be a widespread issue, a single frozen pipe can stop the flow of water to certain taps. Instances such as this require both patience and finesse to fix.
Tips for Fixing Certain Issues
While there are some potential causes that would require the help of a professional, there are some remedies you can try and check yourself before you shell out the big bucks for a plumber.
Fixing Leaky Pipes
How easy it is to fix a leak in your pipes all comes down to how severe it is and where it is located. A leak from a joint can be fixed by retightening or replacing it or even adding some additional sealant.
If the integrity of a certain section of pipe is compromised from damage or rust, a sectional replacement may be necessary. Depending on the complexity, it can be done yourself with a little pre-education from researching your particular setup.
Blockage in Aerator or Line
To clean your aerator, you need to gently unscrew it from the end of the faucet and make sure you take note of the other pieces inside, such as washers or rubber gaskets – you are going to want to put it back in with the same assembly.
You can remove the mineral deposits from it using vinegar or a CLR-type solution. Afterwards, you can screw it back in and see if that helps with the flow of water.
To fix a sediment clog in a water line, you will either need to remove and clean the blocked portion of the line or use air pressure (or negative pressure) to push out the blockage. There are specialty supply line flush kits you can buy from most home improvement stores.
A word of warning – you need to know where the blockage is in order to clear it effectively.
Fixing Your Water Valve
This can be a tricky repair so make sure you know the style of faucet you are about to take apart before you proceed. Most water faucet valves can be accessed by removing the handle and using a wrench to remove the valve nut on top of the valve.
Afterwards, you can remove your old valve and replace it or inspect it to make sure it’s not damaged (after all, it may not be the issue).
Just as with the aerator, take note of the order in which you remove each part so that you can replace it in the exact same way and avoid any further issues.
Fixing Frozen Pipes
If you are able to determine which section of your pipes is frozen and you can access them, you will want to accelerate the thawing process with heat. You can use a blow dryer or a heating pad placed around the section that is frozen until it thaws enough to allow the free flow of water.
This issue is more commonly seen on taps that are next to an outside-facing wall of your house. If your sink is more interior, it’s unlikely that a frozen pipe caused your kitchen faucet to stop working suddenly.
Although it seems like a headache, there are really only a limited number of reasons why there would be no water coming out of your kitchen faucet. Take some time to examine every part of your plumbing setup, and be sure to check the internal parts, like the valve and the aerator.
Just remember, if the problem seems to be deeper than the pipes you can reach by yourself or if the issue is with your water heater, your best bet is to call a professional plumbing company so that no more damage is done to your lines.
