Is your kitchen sink sputtering every time you turn it on? While it may seem like a small nuisance, sputtering faucets can indicate underlying plumbing issues that may need attention. At White’s Plumbing, we aim to help you understand the common causes of this problem and how you can address it. Here’s everything you need to know about why your sink sputters and what you can do to fix it.
What Causes a Sink to Sputter?
Sputtering sinks are caused by interruptions in water flow, and there are several reasons this might happen. The most common culprits include clogged aerators, air in the pipes, and sediment buildup. Sometimes, more complex issues like a faulty pressure regulator or water contamination are to blame.
For a broader look at plumbing issues you may encounter, explore common sink problems. Below, we’ll dig into the specific causes related to sputtering.
1. Clogged Aerator
The faucet aerator is a small screen that filters debris out of your tap water and helps regulate water flow. Over time, dirt, debris, and minerals can accumulate in the aerator, causing blockages and resulting in a sputtering faucet.
How to Fix It:
- Carefully unscrew the aerator by turning it counterclockwise.
- Clean it with soapy water to remove the residue. If it’s heavily clogged, soak it in vinegar for a thorough clean.
- Rinse and reinstall.
Regularly cleaning the aerator once a month can prevent future interruptions.
2. Air in the Pipes
Air trapped in the water lines is another common cause of sputtering faucets. This usually happens when the water supply is interrupted, such as during system maintenance or after pipes freeze in winter.
How to Check for Air in the Pipes:
- Fill a glass with water from the sputtering tap.
- If the water clears from the bottom up, this indicates air in the lines.
How to Fix It:
You can “bleed” the air from your water lines with these steps:
- Turn on all the faucets in your home halfway.
- Allow them to run for two minutes to purge the air from your system.
- Flush the toilets once or twice to ensure no air pockets remain.
If the sputtering persists across multiple sinks, your main water supply line may be damaged. It’s best to contact a plumber in this case.

3. Damaged Valve Cartridge
Inside every faucet is a valve cartridge that controls water flow. Over time, this part can wear out or become damaged, leading to uneven water flow and sputtering.
How to Fix It:
If you’re comfortable with home repairs, follow these steps:
- Consult your faucet’s owner manual for instructions on removing the valve cartridge.
- Take the old cartridge to a hardware store to find a matching replacement.
- Install the new cartridge as directed.
For larger projects, such as replacing fixtures entirely, consider professional help with sink and tub installation.
4. Sediment Buildup in Water Lines
Do you live in an area with hard water? If so, minerals like calcium and magnesium may build up in your pipes over time. This leads to water flow disruptions that can cause your sink to sputter.
Signs of Sediment Buildup:
- Reduced water pressure
- Cloudy or discolored water
- Visible particles (white or brown) coming from the faucet
How to Fix It:
- Turn off your home’s main water valve.
- Open all faucets to drain the system.
- Turn the water back on to flush out any loose sediment.
Installing a water softener is an excellent long-term fix to prevent mineral buildup in the future. If the issue persists, hiring an expert for sink repair near Raleigh, NC can save you further headaches.
5. Faulty Pressure Regulator
The pressure regulator is responsible for keeping your home’s water pressure consistent. If the regulator malfunctions, water flow may fluctuate, resulting in sputtering or uneven pressure.
How to Diagnose a Faulty Pressure Regulator:
- Check your water pressure using a gauge.
- Normal water pressure ranges from 40 to 60 psi. Low or high readings can indicate a problem.
What to Do:
While homeowners can test water pressure, repairing or replacing the pressure regulator is a job for a professional. A plumber can ensure proper installation and consistent pressure going forward.
6. P-Trap Issues
The P-trap is a U-shaped pipe under your sink designed to prevent sewer gases from coming back up. Most sinks need one, but if it’s improperly installed, it can lead to water flow issues or even strange odors. Learn more about the importance of a P-trap for a sink.
7. Contaminated Water or Bacteria
Though rare, contaminants or bacteria in the water supply can also lead to sputtering. Pollutants may enter the water due to broken water mains, aging infrastructure, or improper water treatment.
Signs of Water Contamination:
- Water that smells of sulfur or chemicals
- Cloudy or discolored water
- Health issues, such as stomach discomfort, after drinking from the tap
What to Do:
Stop using the water immediately if you suspect contamination. Contact your local water provider to have the supply inspected and repaired. Once resolved, consider installing a water filtration system to safeguard your home’s water quality.
Quick Fix for Sputtering Sinks
For minor issues like air pockets or clogged aerators, here’s a simple method you can try at home:
- Turn on all faucets in your home halfway.
- Flush all toilets and run water continuously for a few minutes.
- Turn the faucets off one by one.
This method often resolves sputtering caused by trapped air. If the problem persists, it’s time to call in the experts.
Preventing Sputtering Faucets
Prevention is key to avoiding future plumbing issues. Here are a few tips to maintain your plumbing system and ensure smooth water flow:
- Clean faucet aerators regularly to prevent clogs.
- Insulate pipes during winter to avoid trapped air caused by freezing.
- Schedule periodic plumbing inspections to detect and resolve issues early.
- Consider installing a water filtration or softener system to prevent sediment buildup.
