Stop a Small Outdoor Leak Before Cold Weather Arrives
An outdoor faucet leaking before freezing weather can be caused by a worn internal washer, loose packing, a damaged hose connection, or trouble inside a frost-free faucet. Even a slow drip deserves attention, because trapped water can freeze and damage the faucet or the pipe connected to it.
Puget Sound homes can see cold snaps and overnight freezes, so late September is a smart time to inspect outdoor plumbing instead of waiting for a freeze warning. We recommend a few simple visual checks, but leaks near the wall, signs of a damaged frost-free faucet, or moisture indoors call for a licensed plumber.
Find the Source of the Leak
Where the water appears can tell us a lot about the problem. A drip from the spout after you turn the handle off may point to a worn washer, valve seat, or cartridge. Water gathering around the handle can mean the packing is worn or the packing nut has loosened.
Leaks at the hose connection are often simpler, but they still need attention before cold weather. A missing hose washer, worn threads, or a loose connection can let water escape while the faucet is running.
Look closely at when and where the leak happens:
- Water drips from the spout after the faucet is shut off
- Water seeps around the handle or stem
- Water leaks only where the hose connects
- Moisture appears at the faucet base, siding, or nearby indoor wall
Sometimes the faucet is not the true source. An attached hose, splitter, timer, spray nozzle, or vacuum breaker can leak and make the faucet seem faulty. Removing those accessories and checking the faucet directly can help narrow down the issue.
Check Simple Problems Without Causing More Damage
Before temperatures fall, we suggest turning off the outdoor faucet and disconnecting the garden hose. Remove splitters, timers, spray nozzles, and other attachments as well. Leaving a hose connected can trap water in certain outdoor faucets and keep the fixture from draining as intended.
A visual inspection can reveal obvious problems without taking the faucet apart. Check the hose washer, connection threads, and handle for corrosion, cracking, or looseness. Replacing a damaged hose washer or gently correcting a loose hose connection may stop a small connection leak.
Avoid forcing a stiff handle or tightening the faucet aggressively. Corroded parts can break under too much pressure, turning a minor issue into a larger repair. If the handle feels stuck, the faucet will not close completely, or you see heavy corrosion, we recommend leaving the repair to a plumber.
If you know which indoor shutoff controls the outdoor faucet, you may be able to turn off that supply and open the exterior faucet to drain the line. Only do this when you are certain which valve serves the outdoor plumbing. A shutoff that will not move, does not fully stop the water, or begins leaking needs professional attention.
Know When a Frost-Free Faucet Needs a Plumber
A frost-free faucet is designed with its shutoff valve farther inside the wall, where it has more protection from outdoor temperatures. That design helps, but it does not make the faucet immune to freezing damage. A hose left attached during a freeze can hold water in the fixture, while a bent faucet or worn internal stem can also lead to failure.
Pay attention to warning signs that suggest the issue may be inside the wall:
- Water leaks from siding or the wall when the faucet runs
- Moisture appears in a basement, crawlspace, garage, or utility room
- The faucet will not fully shut off after basic checks
- Water flow is weak or unusual after a freeze
- The handle is broken or the faucet has visible damage
A cracked pipe inside a wall may not show itself until the faucet is used again. Water near the faucet base, exterior wall, or nearby indoor areas should not be ignored. If water is actively leaking indoors or pooling near the home, shut off the water supply if you can do so safely and arrange prompt plumbing service.
Protect Outdoor Plumbing Before a Puget Sound Freeze
A little preparation can reduce the chance that an outdoor faucet leaking today becomes a bigger problem after a cold night. Before the first forecasted freeze, we recommend disconnecting and draining hoses, storing them where they will not freeze, and removing hose-end accessories. Confirm that each exterior faucet closes fully and does not continue dripping.
Homes with dedicated indoor shutoffs for exterior faucets may benefit from having those lines shut off and drained for the season. Plumbing layouts vary, especially in older homes, so it is better to have a plumber identify the correct valves when there is any uncertainty. Faucet covers can offer limited protection from wind and cold, but they do not replace draining hoses or repairing a leak.
Exposed plumbing in unheated crawlspaces, garages, and exterior utility areas may also need attention before freezing conditions arrive. The practical goal is simple: remove trapped water, address leaks early, and watch closely for moisture around the faucet, wall, and nearby indoor spaces.
