We recently had an abnormal cold spell. The hose bib on the outside froze but that was it. There was running water inside the house. Now the hose bib is releasing air (I'm sure it is not intaking air) and a small drbble of water. I have let it run for a long period and still air is escaping. There is plenty of water pressure inside the house and I don't see any wet spots outside to indicate a leak. What could the problem be?

Which type of hose bib do you have?
