Turning on the tap and getting a burst of air instead of a steady stream can catch you off guard. It’s a common issue, but it often points to something worth fixing before it grows into a bigger repair. If you’ve been asking, “Why is my faucet sputtering?” a plumbing service in Fort Pierce, FL, such as ACS Rooter One, can help you find the cause.
Below, we explain why this happens.
Air in Water Lines Is the Most Common Cause
Air in water lines is one of the primary reasons faucets sputter. When the system loses pressure and comes back on, air pockets can get trapped inside the pipes. As water pushes through, that air escapes at the faucet, creating bursts and uneven flow.
This is often tied to a water supply interruption, such as routine water system maintenance or a temporary loss of pressure. Homes with private wells may experience similar symptoms after a power outage affects the well pump. Knowing facts about faucets can help you understand why air moves through your fixtures the way it does.
How To Clear Trapped Air
Follow these steps to remove trapped air from sputtering faucets:
- Start with the highest faucet: Open the tap farthest from your main water line, often an upstairs bathroom.
- Work downward: Move to lower faucets one at a time.
- Check outdoor spigots last: These sit at the lowest point in the system and should run clear last.
If you’re still asking, “Why is my faucet sputtering?” after this, the cause may run deeper than trapped air.
A Faulty Faucet Aerator Can Mimic Air Issues
Sometimes the problem isn’t in your lines at all. A faulty faucet aerator can restrict flow and cause sputtering that resembles trapped air. Aerators sit at the tip of the faucet and are prone to mineral buildup over time.
When buildup blocks part of the screen, pressure builds behind it and forces its way through unevenly. Unscrewing the aerator and soaking it in vinegar may clear a clog. If it looks worn or cracked, installing a new one from a hardware store usually solves the issue.
Water Pressure Issues and Deeper Plumbing Problems
Water pressure issues from a failing regulator or a supply line problem can cause similar symptoms and are worth ruling out. If every faucet in the house is affected, the issue may stem from your home’s plumbing system rather than an individual fixture.
Plumbing system leaks in underground lines can let air into the system while reducing pressure. Well pump problems can cause similar symptoms in homes on private well systems, since a worn seal or a struggling pump can draw air into the line along with water.
Checking Your Home’s Water Pressure
A pressure gauge attached to an outdoor spigot can help you check your water levels. Consider these readings:
- Normal range: Household pressure typically falls between 40 and 60 psi.
- High readings: Anything above 60 psi can stress pipes over time.
- Low readings: Anything below 40 psi often indicates a supply or regulator problem.
If your reading falls outside the ideal range, it’s worth having a professional take a look.
When To Call a Plumber
Some sputtering issues clear up with a quick fix, but others need professional attention. If you’ve cleared the aerator and run your faucets with no improvement, it may be time to call for help. A plumber can pinpoint whether the issue is coming from a valve, a regulator, or a line leak.
