Frost-free Hose Bibbs (Bellingham Real Estate Inspections)
Frost-free hose bibbs are nifty devices.  For the most part, they end the worry about outside faucets freezing in winter. At least they do the job here in Whatcom County's maritime climate, where it never gets too frigid.
I have seen problems with the devices but that is, usually, due to a lack of common sense on the part of a homeowner or a builder. In the case of the homeowner, if hoses are left on the faucets during the winter, expect both the hoses and the faucets to freeze.  In some instances, if a builder has run a long supply pipe to a hose bibb through an uninsulated wall, the pipe in the wall might freeze.
Clients often wonder how a frost-free hose bibb operates. It is fairly simple. When you turn the water off with the handle at the front of the hose bibb, that turns off a valve that is farther inside the assembly (back by the threads at the left side in the photo).
