Why Does My Kitchen Faucet Sound Like It Has Air in It?

If your kitchen faucet is sputtering or making strange noises like air is trapped in the pipes, you’re likely dealing with a common plumbing issue. This guide will walk you through the causes and solutions for fixing this problem.

Common Causes of Air in Kitchen Faucets

1. Air in the Pipes

   • Air pockets form when the water supply is disrupted or after plumbing work. These bubbles cause sputtering noises as they move through the pipes.

2. Clogged Faucet Aerator

   • The aerator may become clogged with debris, restricting water flow and allowing air to mix with water, causing sputtering sounds.

3. Faulty Valve Cartridge

   • The valve cartridge controls water flow in your faucet. A damaged or worn cartridge can create air pockets that lead to strange noises.

4. Sediment Buildup

   • Sediment, particularly in homes with hard water, can accumulate in the pipes and restrict water flow, leading to air being trapped.

5. Water Pressure Issues

   • A malfunctioning pressure regulator can cause fluctuations in water pressure, which can result in sputtering sounds.

How to Fix Air in Your Faucet

1. Bleed the Pipes

• How to Bleed the System: Open all faucets in your home and let the water run for a few minutes to allow trapped air to escape.

2. Clean the Faucet Aerator

• Steps to Clean: Unscrew the aerator from the faucet, soak it in vinegar for a few hours to dissolve mineral buildup, scrub with a brush, rinse thoroughly, and reattach it.

3. Inspect the Valve Cartridge

• How to Replace: Turn off the water supply, remove the old valve cartridge, and replace it with a new one from your local hardware store.

4. Flush the Pipes

• How to Flush: Turn off the water supply, open all faucets to drain the system, and then turn the water back on to flush out any sediment.

5. Check for Pressure Regulator Problems

• Test Water Pressure: Use a pressure gauge to test the water pressure. If it's too high or too low, consult a plumber to repair or replace the pressure regulator.

FAQ

Q: Can air in the pipes cause low water pressure?
A: Yes, air pockets can interfere with water flow, leading to low water pressure.

Q: What if my kitchen faucet still sputters after cleaning the aerator?
A: The issue may be with the valve cartridge, sediment buildup, or water pressure. If the problem persists, consult a plumber.

Q: Should I call a plumber if I hear air in my faucet?
A: While most air issues can be fixed with DIY methods, it’s best to consult a plumber if the problem continues or worsens.

Conclusion

A sputtering kitchen faucet is often caused by trapped air, a clogged aerator, or sediment buildup in the pipes. By following these simple steps, you can restore smooth water flow. If the issue persists, a professional plumber can inspect your system and make necessary repairs.
