Homeowners often ask: “Why is my hose faucet leaking when I turn it on?” or “Why does my outdoor faucet or hydrant only leak when in use?” This is a common issue with hose faucets, outdoor faucets, spigots, and hose bibs—and usually points to internal damage.
These fixtures are designed with a valve that stops water flow when turned off. When closed, water pressure is held behind the valve, so even if there’s a crack or failure, water isn’t actively flowing through the damaged area—meaning no visible leak.
Once you turn the faucet on, water begins moving through the system. If there’s a cracked pipe, worn washer, split fitting, or freeze damage, water will escape under pressure—causing a leak that only appears during use.
In Bend and Central Oregon, freeze damage is a leading cause of outdoor faucet and hydrant failures. Water trapped inside the line can freeze, expand, and create fractures that don’t show until water is flowing again.
Common related questions we hear:
Why does my spigot leak when turned on?
Why is my outdoor faucet leaking behind the wall?
Why does my hose bib only leak under pressure?
Even small leaks can lead to hidden water damage inside walls or crawlspaces. If your hose faucet, outdoor faucet, or hydrant is leaking, it’s best to address it early to prevent larger issues.
