Frost-free hose bibs are commonly available and a good idea in areas where freezing temperatures occur, but for a potential homebuyer to request these installed is a little unusual. If it were me and I wanted to sell the house, I would offer a $100 credit per spigot towards the sale price. Of course, that price is likely low depending on how difficult access is to the current spigot plumbing. Separate, dedicated interior shut-off valves serve the same purpose (as long as you remember to close them during cold weather). Good luck and let us know what happens...

: Hi all. I'm in negotiations to sell my house and one of the things the potential buyers asked is that I have frost free hose bibs installed on two outside faucets. I've been in this house for 10 years and have never had any problems ( the house is 60 years old). None of my neighbors have them and, sorry guys- i'm not a plumber, I've never heard of them. How necessary are frost free hose bibs in Boise,ID and do any of you have an idea what it should cost to replace them? Thanks.
