Quick Answer:

If your outdoor spigot shoots air before water, it is usually trapped air or a pressure issue in the line, not an immediate sign of catastrophic damage. Open the valve with a bucket underneath and watch how long the air bursts last; brief bursts are common and often fixable, while long or repeating bursts that accompany pressure loss or leaks need prompt attention.

Why This Happens

Air can get into plumbing for several routine reasons:

• Recent work on the water line, meter, or nearby mains flushed air into your system.
• A well pump or pressure tank cycling oddly can push air into the pipes.
• Loose or failing fittings let air in when pressure drops.
• Trapped air pockets in low points of the line will sputter out when you open a spigot.

Step-by-Step What to Do

Step 1 — Prepare and observe

Place a bucket under the spigot, then open it fully. Watch and time the air bursts. Note whether they stop after a few seconds, continue intermittently, or never stop. This observation helps decide the next steps.

Step 2 — Purge the spigot

Leave the valve open for a minute to let trapped air escape. If the sputtering stops and steady water flows, the problem may be resolved. If air keeps coming, move to other checks.

Step 3 — Check other outdoor and indoor fixtures

Open another outdoor spigot and an indoor cold tap. If the issue is only at one spigot, the problem is likely local to that valve or its immediate piping. If multiple fixtures sputter, the issue may be in a common supply line, pump, or pressure device.

Step 4 — Inspect the spigot and attachments

Remove hoses and spray attachments and try the spigot again. Look for leaks, drips, or visible corrosion. If you see crusting or damage near the fitting, consider that the valve body may be compromised; also check for signs like **outdoor spigot rusts around threads**. If water sprays around the handle instead of the spout, inspect the packing nut and washer — this is related to **spigot sprays from the handle**.

Step 5 — Note timing and recent events

Record when the sputtering started and any recent work (utility repairs, irrigation work, freeze/thaw events). This information is useful if you need professional help.

Step 6 — If you have a well, watch the pump

Listen to the well pump. Rapid on-off cycling or long run times can introduce air into the system. If you notice odd pump behavior, limit usage and consult the pump manual or a technician.

Step 7 — If the spigot continues to sputter, shut it off and get help

If you can’t stop the air, if pressure is low throughout the house, or if visible leaks appear, close the spigot, shut off the outdoor water supply if possible, and contact a plumber.

What Not to Do

• Do not blame city water without testing — observe other fixtures and contact your water utility only after confirming a broader issue.
• Do not force or hammer the valve if it’s stiff; you can cause more damage.
• Do not attempt major repairs on a pressurized line without shutting the water off first.

When to Call a Professional

• Air continues despite purging and affects multiple fixtures.
• There is pressure loss, visible leaks, or water hammer.
• Your well pump cycles abnormally or you suspect a failing pressure tank.
• You see corrosion at fittings or the spigot is damaged around the body or threads.

Safety Notes

• Turn off the water supply before attempting any repairs that require disassembly.
• Be cautious around electrical equipment when water is present.
• Wear gloves and eye protection if you’re handling corroded fittings or working in cold conditions.
• Don’t use open flame or heat sources near frozen pipes; use recommended thawing methods or call a pro.

Common Homeowner Questions

• Why did this start suddenly?
  Often after nearby utility work, pump cycling, or freeze/thaw events that introduce air into the line.
• Can it damage my plumbing?
  Short bursts rarely harm fixtures, but persistent air and pressure swings can stress pipes and pumps.
• Can I fix this myself?
  Yes for short-term trapped air: purge the spigot and check attachments. Call a pro if it keeps coming back or if there are leaks or pump issues.
