Air spitting or sputtering from faucets

Air spitting from faucets on a well system means air is entering somewhere. The most common causes are a pump drawing air because the water level has fallen to it, a leak on the suction side of a jet pump, or naturally dissolved gas. If water runs normally for a while, then sputters and stops, then recovers after several hours of rest, the water level is the likely cause.

Three sources of air

The pump is drawing air. The water level in the well has fallen to or below the pump intake, so it pulls a mixture of water and air. This is the serious one and the one most relevant around Prescott.

A leak on the suction side. Only applies to jet pumps, which pull water up rather than push it. Any crack or loose fitting between the water and the pump lets air in, because that side of the line is under vacuum. A leak there may never drip, since it draws air in rather than pushing water out.

Dissolved gas. Groundwater can carry dissolved gases that come out of solution when pressure drops at the tap. This produces cloudy water that clears from the bottom up, not sputtering. It is a curiosity rather than a problem.

How to tell which one you have

Pattern	Points to
Runs fine, then sputters and stops, recovers after hours of rest	Water level at or below the pump
Worse after heavy use such as irrigation or laundry	Well drawdown outpacing recovery
Constant sputtering, jet pump system, pump also loses prime	Suction side leak
Cloudy water clearing bottom to top, no sputtering	Dissolved gas, harmless
Started right after plumbing work, improving daily	Air introduced during the work
Sputtering plus sand or grit	Pump drawing near the bottom of the well

That last combination is worth noting. Air together with sediment often means the pump is operating close to the bottom of the well, where it picks up both. See cloudy or sandy water.

Why the water level explanation matters here

This symptom is more likely to be about the aquifer around Prescott than it would be in most places.

Groundwater levels in the Chino Valley area have been falling for decades. For a well drilled 50 years ago, depth to water has typically increased 80 to 100 feet, and parts of Williamson Valley have seen reported declines as high as 8 feet a year. Domestic wells have gone dry on the western side of Chino Valley. In March 2025, ABC15 reported that a provider north of Prescott had drilled five essentially dry holes and was hauling water by truck. See falling groundwater and what it means for your well for where those figures come from.

Exempt domestic wells, which are the small private wells most households have, are affected earliest because they tend to be shallower than production wells.

If your well is drawing air, the useful next step is having someone measure the current static water level and compare it against your pump setting depth. That measurement tells you whether you are looking at an equipment conversation or a water conversation. See falling groundwater and what it means for your well.

What not to do

Do not keep running it. A pump cycling air overheats. Submersible pumps rely on water moving past the motor to cool it. Running one dry is a reliable way to destroy it.

Do not assume a new pump fixes it. If the water level is the problem, an identical pump at the same depth reproduces the problem immediately.

Do not ignore it because the water still mostly works. Intermittent air is usually the early stage of something that gets worse.

What to tell whoever you call

• Whether sputtering is constant or comes and goes
• Whether it correlates with heavy water use
• How long recovery takes after the system rests
• Whether there is sand or grit alongside the air
• Whether you have a jet pump or a submersible
• Pump setting depth and total well depth if you have the record
