Can a frost-proof outside faucet freeze?

Yes, unfortunately we get calls every spring to replace outside faucets that have sprung a leak in a customer’s basement. In most cases, they are frost-proof outside faucets that have frozen for one of a few reasons. One, a hose was left on the faucet in the winter, not allowing it to completely drain when shut off. Two, and the most common cause, installation error. Frost-proof faucets must be installed properly to eliminate the possibility of freezing. We warranty all installations, so making sure they are installed properly is a must.
