Hose bib

A hose bib is the spigot on the outside of your house. In Iowa the frost-free style matters: it shuts the water off a foot or more inside the warm wall so the exposed part cannot freeze. Leaving a hose attached over winter defeats that design and is one of the most common causes of a split pipe found the following spring.

Why hose bibs cause so much spring water damage in Iowa

A frost-free hose bib only protects you if it can drain: the actual valve sits back inside the heated wall, and the long barrel between valve and spout is supposed to empty after each use. Leave a hose connected into winter and that barrel stays full, freezes, and splits — but here is the cruel part: the split is behind the valve, so nothing leaks until you open the spigot in April. The first long hose session of spring then quietly pours water inside your wall or basement ceiling, and the damage bill has nothing to do with the cheap fixture that caused it.

How to spot a hose bib that has already split

On the first spring use, have someone watch inside — basement ceiling, rim joist, or the wall behind the spigot — while the hose runs for several minutes. Water appearing inside, a spigot with noticeably weaker flow than last year, or one that drips from the handle or barrel after shut-off all point at freeze damage or a worn stem. An older non-frost-free bib on an unheated wall is worth upgrading on principle; the frost-free replacement costs little compared to one drywall repair.
