Why Your Faucets Are Sputtering Air and Water

Experiencing this problem right now? Call us for immediate assistance.

When your faucets sputter air before delivering water—or continuously mix air with water—something is wrong with your well system. This sputtering indicates air is entering your water lines somewhere, and identifying where helps determine the fix.

Common Causes

Low Water Level: If the water table has dropped, your pump may be drawing both water and air from near the surface.
Failing Pump: A pump with worn seals or impellers can draw air through the wear points even when submerged.
Cracked Drop Pipe: A crack or joint separation in the drop pipe allows air to enter when the pump isn't running.
Leaking Foot Valve: A failing foot valve allows water to drain back, letting air into the system.
Jet Pump Suction Leak: For jet pumps, any air leak on the suction side causes sputtering. Even tiny leaks matter.
Methane or Gas in Water: In some areas, natural methane in groundwater causes similar sputtering symptoms.

Warning Signs to Watch For

Air bursts from faucets when first turned on
Continuous bubbling or sputtering during water use
White, cloudy water that clears from the bottom up
Fluctuating pressure during use
Pump cycling more frequently
Problem worse after pump sits idle

How to Fix This Problem

1. Identify When It Occurs

Air only when first using water points to drainage issues. Continuous sputtering suggests ongoing air infiltration.

2. Check Well Water Level

Have a professional measure static and pumping water levels. If the pump intake is too close to the surface, it may draw air.

3. Inspect Jet Pump Connections

For jet pumps, check all suction line connections. Tighten fittings and look for cracks in plastic pipes or worn gaskets.

4. Pressure Test the System

A professional can pressure-test the drop pipe assembly to identify cracks or separations underground.

5. Check for Gas in Water

If you have a sulfur smell with the sputtering, you may have methane or hydrogen sulfide. This requires water testing and possibly treatment.

When to Call a Professional

While some minor issues can be addressed by homeowners, well system problems often require professional diagnosis. Call Southern California Well Service if:

You're not comfortable working with electrical systems
The problem persists after basic troubleshooting
You notice multiple symptoms at once
Your well is over 10 years old and hasn't been serviced

We offer same-day emergency service throughout San Diego, Riverside, and San Bernardino counties.

Frequently Asked Questions

Why does my well water sputter air?

Air enters the system through a leak, low water level, or failing pump. The sputtering is the air being pushed out when you use water.

Is air in well water dangerous?

Air itself isn't dangerous. However, if the air includes methane or other gases, it could indicate contamination requiring testing.

How do I get air out of my well system?

Open faucets (starting farthest from the pressure tank) and let them run until steady water flows. If sputtering continues, the air source must be fixed.

Can a bad pressure tank cause sputtering?

A waterlogged tank causes rapid pump cycling, which can introduce air. Proper tank function helps prevent sputtering.
