What Makes Your Kitchen Faucet Sputter?

Kitchen faucet that keeps sputtering

Wondering why your kitchen faucet is misbehaving with annoying sputtering water? It’s a perplexing situation that can leave you scratching your head. But fret not! Below, we’ll explore the potential culprits behind this issue and provide practical solutions to help you regain a smooth and consistent water flow in your kitchen sink.

Air in the Water Line

A frequent culprit behind a sputtering faucet is the emergence of air bubbles within the water pipes. This issue commonly arises during winter, when freezing temperatures prevail, or during times of heightened water usage, such as scorching summer heatwaves. Additionally, air bubbles may be introduced into the system during hydrant maintenance activities, where the disturbance of silt occurs.

To determine if there is air present in the water lines, a simple test can be performed. Fill a glass with water and carefully observe whether it clears from the top or bottom. If the water clears at the bottom first, it is likely that air is trapped within the pipes.

Solution: In most cases, sputtering caused by air bubbles is a momentary issue that can be resolved by simply running the cold water taps for a few minutes to purge the air from the pipes. However, if multiple sinks are sputtering or if the issue persists, it could indicate a more significant problem such as damaged plumbing or a break in the main water supply lines. In such cases, it is advisable to contact a professional plumber to inspect and address the issue with the main lines.

Aerator Issues

The aerator is a small device located at the end of the faucet spout that helps regulate water flow and control the spread of water. Over time, sediment, debris, or mineral deposits can accumulate in the aerator, causing it to clog. When water is forced through a clogged aerator, it can result in sputtering or uneven water flow.

Solution: Remove the aerator from the faucet spout and clean it thoroughly with soapy water. Soak it in vinegar to dissolve mineral deposits or use a brush to remove debris. If cleaning the aerator is ineffective, replace it with a new one.

Faulty Valve Cartridge

A clogged or damaged valve cartridge can result in sputtering when you turn on the kitchen faucet. The valve cartridge, responsible for controlling water flow and temperature, can become worn out or clogged with sediment over time.

Solution: Replace the valve cartridge with a new one that is compatible with the faucet model. A professional plumber can handle the replacement to ensure proper installation and functionality of the new valve cartridge.

Water Pressure Problems

Faucet with bad water pressure

Inadequate water pressure or inconsistent water pressure can cause a sputtering faucet. Low water pressure may be due to a variety of factors, including a partially closed water valve, a blockage in the plumbing system, or a problem with the municipal water supply.

Solution: Check the water pressure in other faucets throughout the house to determine if the issue is localized. If it’s only the kitchen faucet, check the faucet’s water supply lines for any kinks or obstructions. Ensure that the water shut-off valves are fully open. If necessary, contact a plumber to identify and resolve any blockages or restrictions in the plumbing system.

Plumbing Blockages

A blockage or restriction in the plumbing system can disrupt the water flow and cause sputtering water. If there is a partial blockage in the water pipes leading to the kitchen faucet, it can result in uneven water flow and sputtering.

Solution: Call a plumber to inspect the plumbing system and locate the blockage. A professional plumber will use tools like drain snakes or hydro-jetting equipment to remove the obstruction. In some cases, disassembling parts of the plumbing system may be required to access and clear the blockage effectively.

Water Heater Issues

Sputtering may specifically occur when using hot water. Sediment buildup in the water heater tank can cause the water to sputter as it flows out. Also, an old or faulty water heater may cause issues.

Solution: A plumber can perform a thorough flushing of the water heater. They will drain the hot water tank to remove sediment and debris, ensuring smoother water flow. They can also inspect the hot water heater for any other issues and address them accordingly.
