Why Your Outdoor Spigot Is Leaking Even When the Water Is Off

The most common cause is a worn washer or damaged valve seat inside the faucet body. When these components fail, water continues to seep through even when the handle is fully closed.

Common Causes of Outdoor Faucet Leaks
Understanding what makes your spigot leak helps you decide whether to DIY or call a professional. Here are the most frequent problems we see in Fairfield County homes:
Worn Washer Failure
Compression faucets use rubber washers that degrade over time. Hard water in Greenwich accelerates this wear, causing the washer to become brittle and cracked. You’ll notice water seeping around the handle when the faucet is off. This is the easiest fix for homeowners comfortable with basic tools.
Corroded Valve Seat
The valve seat is the brass surface where the washer presses to stop water flow. Mineral deposits from Greenwich’s water supply can pit and corrode this surface. Even a new washer won’t seal properly against a damaged valve seat. You’ll need a seat wrench to remove and replace it.
Frozen Pipe Damage
Greenwich experiences freeze-thaw cycles that can split pipes behind walls. A burst pipe may only leak when the faucet is on, but freeze damage can also cause slow seepage through hairline cracks. Feel the wall behind the spigot for cold spots or moisture.
Loose Packing Nut
The packing nut seals the valve stem where it passes through the faucet body. If it’s loose, you’ll see water dripping from around the handle stem when the faucet is on. This is different from washer leaks – the water comes from above the handle rather than the spout.
Broken Vacuum Breaker

Modern frost-free faucets include a vacuum breaker cap on top. When this fails, water drips from the cap opening. This is a safety device required by Connecticut plumbing codes to prevent backflow contamination. A broken vacuum breaker won’t stop the faucet from working but violates code. Plumbing Stamford.
Step-by-Step DIY Fixes for a Dripping Hose Bibb
If you’re comfortable with basic plumbing repairs, you can often fix a leaking outdoor faucet yourself. Here’s the process we recommend for Greenwich homeowners:
- Turn Off Water Supply
Locate the shut-off valve for your outdoor faucet. Many Greenwich homes have separate valves in the basement or crawl space. Turn clockwise until fully closed.
- Drain Remaining Water
Open the outdoor faucet to release pressure. Leave it open while you work to prevent water spray when disassembling.
- Remove Handle
Unscrew the handle screw, usually under a decorative cap. Pull the handle straight off the stem.
- Remove Packing Nut
Use an adjustable wrench to turn the packing nut counterclockwise. If it’s stuck, apply penetrating oil and wait 15 minutes.
- Replace Washer
Remove the old washer from the valve stem end. Take it to the hardware store for an exact match. Install the new washer.
If replacing the washer doesn’t solve the problem, you may need to replace the valve seat or the entire faucet assembly. Greenwich’s older homes often require specialty parts that aren’t available at big box stores.
When a Leaky Spigot Becomes a Plumbing Emergency
Not all leaks are simple DIY fixes. Some indicate serious problems that need immediate professional attention. Here’s when to call United Plumbing at (475) 320-3733:
Water Behind the Wall – If you notice water stains, mold, or soft drywall near your outdoor faucet, you likely have a burst pipe inside the wall. This requires emergency repair to prevent structural damage.
Multiple Fixture Leaks – When several faucets in your home start leaking simultaneously, it often indicates high water pressure or a failing pressure regulator. This affects your entire plumbing system.
Sewer Smell – A foul odor from outdoor drains combined with faucet leaks could mean a broken sewer line. This poses health risks and requires immediate professional remediation.
Flooding – If your leak has caused standing water around your foundation, you need emergency water extraction and plumbing repair to prevent basement flooding.
Protecting Greenwich Homes from Frozen Outdoor Pipes
Greenwich’s coastal location doesn’t prevent freezing temperatures. Our area experiences 20-30 freeze-thaw cycles each winter, according to NOAA climate data. This constant expansion and contraction stresses plumbing components. NOAA climate data.
Frost-Free Faucets – These faucets have a long stem that places the water shut-off inside your heated home. When installed correctly with a slight downward pitch, they drain completely when shut off. This prevents freezing damage.
Shut-Off Valves – The best protection is a dedicated shut-off valve inside your home. Close it in late fall, then open the outdoor faucet to drain remaining water. This eliminates water that could freeze and burst pipes.
Insulation – Foam faucet covers provide minimal protection in Greenwich’s climate. They’re better than nothing but won’t prevent freezing during extended cold snaps. Focus on proper drainage instead.
Heat Cables – For exposed pipes in unheated areas like garages or crawl spaces, heat cables can prevent freezing. Install them with a thermostat to activate only when temperatures drop below 38°F.

Frequently Asked Questions
Why does my outdoor faucet still drip after replacing the washer?
The valve seat is likely corroded or damaged. Hard water in Greenwich causes mineral buildup that pits the brass surface. You’ll need a seat wrench to remove and replace the valve seat, or the entire faucet may need replacement.
How can I tell if my outdoor faucet is frost-free?
Measure the stem length. Frost-free faucets have stems 10-20 inches long, with the shut-off valve inside your home’s heated space. The handle is usually perpendicular to the house rather than angled outward like standard faucets.
Should I turn off my outdoor water in winter?
Yes, if you have a separate shut-off valve. Close it in late fall, then open the outdoor faucet to drain remaining water. This is the most reliable freeze protection for Greenwich homes, even with frost-free faucets. The Most Reliable Drain Cleaning Services in Old Greenwich.
How much water does a dripping outdoor faucet waste?
A faucet dripping one drop per second wastes about 3,000 gallons per year. That’s enough to fill a small swimming pool or take over 180 showers. The EPA WaterSense program estimates this costs the average homeowner $30-50 annually.
Can I use my outdoor faucet in winter if it’s dripping?
No. A dripping faucet indicates a failed seal that allows water to remain in the faucet body. When temperatures drop below freezing, this water expands and can split pipes. Fix the leak before winter use.
