Most likely causes
Freeze damage
A hose left connected traps water in a frost-free sillcock, which can split it inside the wall.
Worn washers
Compression-style spigots drip as washers wear.
Missing vacuum breaker
Without a vacuum breaker, hose water can siphon back into the house supply.
Irrigation line leaks
Underground sprinkler lines and valves leak from freeze damage, root pressure or mower strikes, often showing up as soggy patches or a high water bill.
How the problem is diagnosed
- Run the hose and check inside for leaks
- Check washer and stem
- Check for vacuum breaker

Outdoor Plumbing & Hose Bibs: common questions
Why does my outdoor faucet leak inside the house?
A frost-free sillcock that froze with a hose attached can split inside the wall. It leaks only when the faucet is opened, which is why it often appears in spring.
Do I need to shut off outdoor faucets in winter?
In freezing climates, yes for standard spigots: close the interior shutoff and drain the line. Frost-free sillcocks still need the hose removed.
How do I know if a frost-free spigot is installed correctly?
It should slope slightly downward toward the outside so water drains out of the valve body, and the valve seat should sit inside the heated part of the wall.
Can I add an outdoor faucet to my house?
Usually. A plumber taps a nearby supply line, adds an interior shutoff, and installs a frost-free sillcock with a vacuum breaker.
Why is there low pressure at my outdoor faucet only?
A partly closed interior shutoff, a worn valve washer, mineral buildup or a kinked hose are the usual causes when only the outdoor faucet is weak.
