Why Is My Kitchen Sink Sputtering?

Sink Water Running

A sputtering kitchen sink can be an annoying and perplexing problem for homeowners. When you turn on the faucet, instead of a steady stream of water, you may hear a series of spitting, spluttering sounds accompanied by intermittent bursts of water. This issue can disrupt your daily activities in the kitchen and make it difficult to perform basic tasks like washing dishes or filling a pot with water. Understanding the causes behind a sputtering sink is crucial in order to resolve the issue effectively.

One of the primary reasons for a sputtering sink is air trapped in the water pipes. When air becomes trapped in the plumbing system, it can create pockets of air that disrupt the flow of water. Another common cause is a clogged or damaged aerator, which is a small device located at the end of the faucet spout that mixes air with water to create a smooth and consistent stream.

How Do You Fix A Sputtering Sink?

Fixing a sputtering sink depends on the underlying cause. Here are a few steps you can take to address the issue:

  1. Check for air in the water pipes: Start by turning on all the faucets in your home, including the ones in the basement and on upper floors. Let the water run for a few minutes to allow any trapped air to escape. If the sputtering persists, move on to the next step.
  2. Inspect and clean the aerator: Remove the aerator from the faucet spout and clean it thoroughly. Over time, mineral deposits and debris can accumulate in the aerator, causing clogs and uneven water flow. Soak the aerator in vinegar or a descaling solution to remove any stubborn deposits. Once clean, reattach the aerator and check if the sputtering has stopped.
  3. Check for plumbing leaks: Sputtering can also be caused by leaks in the plumbing system. Inspect the pipes under the sink and look for any signs of leakage. If you notice any leaks, it is best to call a professional plumber to fix the issue.

Can Air In Water Pipes Cause Damage?

While air in water pipes may not cause direct damage, it can lead to other problems if left unaddressed. When air gets trapped in the plumbing system, it can create pressure imbalances, resulting in sputtering faucets and reduced water flow. However, the presence of air does not typically cause long-term damage to the pipes themselves.

That said, if the sputtering issue persists, it could indicate a larger problem within the plumbing system. Continuous sputtering could put additional stress on the pipes and fittings, potentially leading to leaks or bursts in the future. Therefore, it is essential to identify and fix the underlying cause of the sputtering to prevent any potential damage to the plumbing system.

Why Does My Boiling Water Tap Sputter?

Boiling water taps, also known as instant hot water dispensers, are a convenient addition to any kitchen. They provide immediate access to hot water for various purposes such as making tea, coffee, or cooking. However, if your boiling water tap is sputtering, it can be frustrating and diminish the functionality of the device.

The sputtering of a boiling water tap is often caused by mineral deposits or debris clogging the tap’s filter or nozzle. Over time, water impurities, such as limescale, can accumulate and obstruct the flow of water, resulting in sputtering. Additionally, air trapped in the pipes connected to the boiling water tap can also cause sputtering.

What Causes A Tap To Lose Pressure?

A tap can lose pressure due to various factors, and understanding the cause is essential for resolving the issue. One common reason for a tap to lose pressure is mineral buildup in the aerator or valves, which obstructs the water flow and reduces pressure. Another possibility is partially closed valves, where the tap’s shut-off valves are not fully open, restricting the water flow. 

Additionally, leaks in the plumbing system can lead to a drop in water pressure. It is important to inspect the pipes for any signs of leakage and promptly fix them to prevent further damage. In some cases, a decrease in water pressure may be due to municipal supply issues, so contacting the local water utility provider can help determine if there are any known problems in the area. Clogged pipes can also impede water flow and cause a loss of pressure, requiring professional plumbing services for effective resolution.


A sputtering sink can be a bothersome problem, but with proper troubleshooting, it can be resolved. Air trapped in water pipes, clogged aerators, and plumbing leaks are common culprits behind the sputtering issue. Taking steps such as releasing trapped air, cleaning aerators, and addressing leaks can help restore normal water flow.

Similarly, a sputtering boiling water tap can be fixed by cleaning the filter or nozzle and releasing trapped air. Loss of pressure in a tap can be caused by mineral buildup, partially closed valves, pipe leaks, or supply issues. Identifying the specific cause and taking appropriate measures, such as cleaning, repairing, or contacting professionals, will help restore the tap’s normal water pressure.

If you encounter persistent issues or are unsure of how to address the problem, it is advisable to seek the assistance of a qualified plumber. Promptly resolving sputtering and low-pressure issues will ensure a smooth and functional water supply in your kitchen, making daily tasks more convenient and enjoyable.
