Why Your Outdoor Hose Bib Might Leak This Spring — And What to Do About It

As the weather warms up around Spencer and the rest of Worcester County, a lot of homeowners head outside to hook up the garden hose for the first time. It’s usually a sign that spring has officially arrived… until suddenly you hear running water where it definitely shouldn’t be.

Every year, one of the most common spring plumbing surprises we see is a broken outdoor hose bib (also called a spigot or sillcock) that cracked during the winter. You often won’t know it’s damaged until you turn it on for the first time—because the leak doesn’t show up outside. It shows up inside your home.

Why Hose Bibs Break Over the Winter

Even “frost-proof” hose bibs can fail if they weren’t fully drained before freezing temperatures hit. When water gets trapped inside the line, it expands as it freezes, and the pressure can crack the internal pipe. The exterior portion may look perfectly fine, so many homeowners don’t realize anything’s wrong.

But the first time you open that valve in April or May, water rushes through the cracked section—often inside the wall—causing leaks, water damage, or even mold if it goes unnoticed.

How to Check for a Broken Hose Bib

Before you let that hose run for the season, do a quick check:

  • Turn the hose bib on slowly. Listen for dripping or rushing water behind the wall.
  • Go inside the house near where the bib is located. Look for damp drywall, water stains, or swelling baseboards.
  • Check the basement. Many hose bib connections run through unfinished basement areas—look for dripping around the sill plate or copper piping.
  • Watch the water meter. If it continues moving when no water is running inside, you may have a hidden leak.

What to Do If Water Starts Leaking Inside

If you notice water coming into the house after turning on your hose bib, here’s what to do:

  • Shut the hose bib off immediately. This stops additional water from entering the wall.
  • Turn off the water supply to the hose bib. Many homes have an interior shutoff valve for exactly this reason.
  • Dry the area as much as possible. Towels, fans, and dehumidifiers help reduce moisture and prevent mold.
  • Do not use the outdoor faucet again until it’s been repaired or replaced.
