No water in kitchen but everywhere else? The kitchen faucet not dispensing water is a common scenario that frustrates you when you need the sink. You cannot clean your veggies or utensils or dispense water for other use. It is even more frightening if water flows in other points in your home.  

The primary culprits for no water in kitchen but everywhere else are airlocks, blocked faucets, decreased pressure, frozen water, or water heater problems. Don’t panic, as all the above issues are resolvable. You must examine your tap step by step to analyze and correct the situation. If you aren’t sure about undertaking the task, you can call a kitchen plumber to bail you out. But have a look at the common causes of this annoying issue. 

1. Decreased Pressure

Decreased pressure occurs when there is an issue with your waterline. The top tank may not have enough water, or there flow from your supplier is low. Also, the plumbing system may have issues with blockage or leakage. 

How To Fix

A decrease in pressure has several causes. Before concluding, examine the causes to determine the solution;

• Low Water Level: If the water in your top tank is low, there is no way you will have water in your kitchen faucet. Faucets on a lower level than your kitchen sink will have flowing water. Fixing this error requires you to pump water from your reservoir or ask your provider to resolve the shortage.

• Plumbing System Leakage: A physical examination of the piping system can reveal a leakage causing your kitchen faucet not to dispense water. Such an issue requires the right tools and expertise to resolve. So, call your kitchen and bath plumber.

2. Broken Kitchen Faucet

Your kitchen faucet could be why there is no water in the kitchen sink, but there isn’t everywhere else. Mostly, a broken kitchen faucet will begin leaking at the point of breakage and will not let water flow into the sink.

How To Fix: 

The kitchen faucet not working could mean an airlock. Also, no water coming out of hot faucet means leaks and limescale. However, if it is broken, the best approach to this issue is to replace it with a new one. For all faucet issues, seak expertise. If you are going to attempt the repair, ensure that you order the right match and consider durability. Solid brass kitchen faucets last longer and require minimal care. The metal does not rust and endures hard water. Don’t worry about the price; the faucets cost as little as $150 or less.

3. Blockages 

A blocked kitchen faucet cannot dispense water in your sink. The blockage may result from debris in the system or a blocked aerator. Also, it can be a clogged cartridge that is not allowing water to flow into your kitchen sink. 

How To Fix

The only way to fix a blocked kitchen faucet is to examine and unclog the aerator and the cartridge.  

We begin with the cartridge. This feature on your faucet controls the hot and cold water flow. It mixes the water to achieve the right temperature. The cartridge lies inside the faucet’s handle or body and is replaceable. 

Steps To Unclog Faucet Cartridge;

• Grab a wrench, pliers, and a screwdriver.
• Remove the attaching screw and take off the handle.
• After removing the handle, unscrew the retaining nut to access the cartridge.
• Examine the cartridge and remove any clogs, including debris, sediment, or mineral build-up.
• Use a toothbrush to clean the cartridge gently. To remove stubborn deposits, soak it in a water and vinegar mixture (1:1). 
• If you notice a damaged cartridge, don’t panic, as it is replaceable.
• Turn on the water to flush the faucet.
• Reattach the cartridge and secure the retaining nut and handle.
• Test your faucet by turning on the water supply.

Steps To Unclog Faucet Aerator;

The aerator is the small device at the end of the faucet spout. It helps to mix air with water, thus reducing splashing and conserving your water. Here are the steps to unclog the aerator;

• Turn off the water supply and locate the shut-off valves under the sink.
• Turn the valves clockwise to stop the water flow.
• Locate the aerator at the faucet’s tip. It is a small round device with a mesh screen. 
• Wrap the pliers’ jaws with a cloth to avoid scratching the faucet.
• Grip the aerator tightly and turn it counterclockwise( it should unscrew easily).
• Remove and inspect the aerator for debris and other buildup.  
• Clean it under running water while removing any loose debris.
• Soak the aerator in water and vinegar for 30 minutes to loosen the dirt and remove the lime scale. 
• Install the aerator by screwing it back onto the faucet. Do not over-tighten, as it can damage the faucet threads.
• Turn on the water supply and see if the aerator works. 

4. Frozen Water  

During the winter, water freezes inside pipes. So, water won’t flow, hence the problem you are experiencing.  

How To Fix

Thaw water in the pipes. According to South End company, you can thaw the frozen water in the kitchen pipes by heating the pipe with a hair dryer. An open flame can melt and damage the pipe, so use a hair dryer to heat the pipe for about 30 minutes. Once the water is warm, turn on the faucet and keep the water running for some minutes. It will melt the ice.

5. Faulty Water Heater

No water in rv kitchen sink but everywhere else? Check your under-sink water heater. It may be faulty or have debris buildup. If there is a blockage, the tubes will not allow water to flow with pressure.

How To Fix:

Examine the water heater and clear the sediments. If the unit is broken, get an electrician to replace or resolve the issue.

6. Damaged Water Valve

The water valve has a mechanism that controls the water flow into the water tap. If it closes and doesn’t open or has debris buildup, the water will stop flowing. You need to correct that.

How To Fix

One of the ways to fix a valve issue is to unclog it. Rust, mineral, and debris buildup can damage the internal mechanism. Also, a worn-out seal can cause leakage. You may need a plumber to remove the valve, inspect, clean/replace it.

7. AirLock

An air bubble in the pipe will stop the water flow in your kitchen sink. It can partially affect your home where you have some faucets with flowing water and others dry. An airlock is easy to remove.

How To Fix An Airlock

• Increase the water pressure in the pipes to push the bubble out through the faucet.
• Open all the faucets and leave them running for a minute.
