Quick Answer:
If the outdoor spigot shows clear signs of leaking, freezing damage, or fails simple isolation and repair steps, call a plumber. Before you call, review the symptom list below and write down exactly what you tested so the pro can diagnose faster and avoid unnecessary emergency charges.
Why This Happens
Outdoor spigot problems usually come from a few common causes:
- Worn or torn washers and valve seats inside the spigot.
- Backflow or pressure changes when a hose or irrigation system is attached. See Outdoor Spigot Leaks Only When Hose Is Attached for that specific pattern.
- Water hammer or pipe movement when the spigot closes. The issue can sound like knocking or hammering; see Outdoor Spigot Makes Hammering Noise When Closed for that symptom.
- Freezing that cracked the spigot or supply line.
- Faulty shutoff valve inside the house or corrosion at the connection points.
Knowing which of these fits your situation helps you decide whether it’s a do-it-yourself fix or needs a pro.
Step-by-Step What to Do
1. Look over the symptom list
- Is water dripping steadily from the spigot when it’s closed?
- Does it only leak when a hose or device is attached?
- Is there noise (hammering, knocking) when you close the spigot?
- Do you see frost, cracked metal, or water pooling at the foundation?
- Is water pressure low or are other fixtures affected?
2. Try simple isolation tests
- Turn the spigot fully off and remove any hose or attachments.
- Place a towel under the spigot and watch for leaks for a few minutes.
- Check an indoor shutoff for that spigot (if present) and close it to see if the leak stops.
3. Test the hardware
- If comfortable, open the spigot and feel for roughness in the handle or unusual play that suggests worn parts.
- If the spigot uses a removable packing nut or screw-in stem, note whether the handle assembly is loose or corroded. Don’t force parts that seem frozen.
4. Document everything you tested
Write down what you did and what happened. Include:
- Which tests you ran (hose removed, indoor shutoff closed, towel check, handle movement).
- What you observed (drip rate, noises, whether shutting the indoor valve stopped the leak).
- Any visible damage (cracks, corrosion, ice).
Documenting your checks saves time and money. It gives the plumber a clear starting point so they can decide whether to bring parts or send a team for an emergency repair.
5. Try a basic do-it-yourself fix only if safe
- Replace a worn garden-hose washer if the leak is only at the spout when open and the spigot is otherwise solid.
- Tighten a loose packing nut slightly if the stem packing is leaking, but stop if you see corrosion or breakage.
What Not to Do
- Do not call a plumber without documenting checks. Plumbers need to know what you already tested to give accurate advice and avoid unnecessary visits.
- Do not use an open flame or heat gun on frozen pipes—this is dangerous and can make damage worse.
- Do not force stuck valves or try to cut frozen pipes without turning the water off and knowing where the shutoff is.
When to Call a Professional
- If the spigot leaks despite removing hoses and closing indoor shutoffs.
- If you suspect a frozen or burst supply line (visible cracks, ice, water pooling at the foundation).
- When leaks continue after replacing washers or tightening packing, or if internal parts are corroded.
- If you hear persistent hammering or loud knocking that suggests pipe support or pressure issues.
- If water is entering the house foundation or affecting multiple fixtures—this can indicate a larger supply problem.
- If you can’t locate or safely reach the shutoff valve or the repair requires soldering, replacing buried lines, or cutting into siding or foundation.
When you call, tell the plumber the documented tests you performed and the symptoms you observed. That information helps them arrive prepared and may avoid extra trips.
Safety Notes
- Always shut off the nearest indoor shutoff or the main water before attempting repairs that open the spigot hardware.
- Wear gloves and eye protection when working with corroded fittings or frozen pipes that may break.
- Don’t heat pipes with an open flame; use safe warming methods and call a professional if you’re unsure.
- If water is pooling near the foundation, disconnect power to nearby electrical outlets and call a pro if there’s any risk to wiring.
Common Homeowner Questions
- Q: Can I fix a leaking outdoor spigot myself?
A: Often yes for simple washer or packing issues, but stop and call a plumber if parts are corroded, frozen, or the leak persists. - Q: How should I prepare before a plumber arrives?
A: Document the tests you ran, note exact symptoms, shut off the water if safe, and clear access to the spigot. - Q: Is a noisy spigot an emergency?
A: Not always, but persistent hammering or sudden loud knocks can indicate pressure or support problems that should be checked promptly.
