Outdoor Spigot Handle Leaking: Packing Nut and Hose Bib Checks
A drip from behind an outdoor faucet handle is different from water leaking at the hose connection or from the wall. It usually means the valve stem packing is loose or worn, but a cracked frost-free sillcock, failed stem, or missing interior shutoff can make the repair more involved. Because an outdoor spigot passes through the exterior wall, a small leak can wet siding, insulation, or a basement ceiling. Start by identifying where the water appears and locating the indoor shutoff. Do not force a frozen handle or attempt to repair a split faucet body under pressure.

Common Symptoms
- Water seeps from behind the handle only while the spigot is turned on
- The faucet handle feels loose, stiff, or needs to be overtightened to stop water
- A drip continues after the handle is closed
- The outdoor faucet leaked after freezing weather or a hose was left connected
- Water appears at the wall, indoors, or from the faucet body rather than the handle area
Most Likely Causes
- 1
Loose Packing Nut
The small nut directly behind the handle compresses packing around the valve stem. It can loosen over time and allow water to escape when the valve is open.
- 2
Worn Stem Packing or O-Ring
Packing material and stem seals wear from use and mineral buildup. Tightening the packing nut may help briefly, but a damaged seal usually needs replacement.
- 3
Worn Valve Washer or Stem
A faucet that also drips from the outlet when closed may have a worn washer, seat, or stem that requires a repair kit matched to the faucet model.
- 4
Freeze-Damaged Frost-Free Faucet
A hose left attached during freezing weather can trap water in a frost-free sillcock. A split tube may leak inside the wall or from the body and requires prompt plumbing repair.

Quick DIY Checks
Do not turn or tighten an outdoor spigot by twisting the entire faucet body. Movement at the wall can damage hidden piping and create a leak inside the house.
Treat water at the wall, in a basement ceiling, or after a freeze as a possible split frost-free faucet. Shut off the water if possible and call a plumber promptly.
Never leave a hose connected to a frost-free faucet during freezing weather. Remove hoses and drain the faucet using the indoor shutoff when your climate requires winterization.
- 1Step 1 — Remove the hose, splitter, and any quick-connect fitting. Dry the faucet, then open it slowly and watch whether water comes from the handle, hose threads, vacuum breaker, or wall. The leak location determines the next step.
- 2Step 2 — Locate the indoor shutoff for the outdoor faucet before loosening anything. If there is no accessible shutoff, water is leaking indoors, or the faucet is in a finished wall, call a plumber rather than working on a pressurized valve.
- 3Step 3 — For a small handle-area seep only, use two wrenches: hold the faucet body steady and tighten the packing nut a very small amount. Do not twist the faucet body or overtighten the nut, which can damage the stem or make the handle bind.

Repair vs Replace
A handle-area seep from a sound faucet is often repairable with a careful packing adjustment or matched seal kit. Replace the faucet when the body or internal tube is cracked, the stem is damaged, or freeze damage has affected concealed piping.
Est. Repair Cost
$3–$20 for packing, an O-ring, or a repair kit; $15–$50 for basic tools
Est. Replacement Cost
$200–$650 for professional frost-free sillcock replacement; more if hidden piping or wall finishes are damaged

Frequently Asked Questions
- Can I tighten the nut behind a leaking outdoor faucet handle?
- Often, but only a small amount. Hold the faucet body steady with a second wrench so you do not twist the piping in the wall. If the seep continues, replace the packing or call a plumber.
- Why does my outdoor faucet leak after winter?
- A connected hose can trap water in a frost-free faucet and allow it to freeze. A split may leak only when the faucet is on and can send water into the wall, so it needs prompt inspection.
- Should I replace a faucet that drips from the handle and outlet?
- Not always. A matched stem repair kit may address both seals if the faucet body is sound. Replace or hire a plumber for a cracked body, damaged stem, or inaccessible interior shutoff.
