I AM LOOKING FOR AN ADD ON FAUCET THAT AUTOMATICALLY DRIPS WHEN THE TEMP FALLS BELOW FREEZING. I SAW THEM AT A HARDWARD SHOW IN KENTUCKY SEVERAL YEARS AGO BUT CANT REMEMBER THE BRAND OR LOCATION OF COMPANY.
if it is outside for a hose but coming out of the wall many companys make a frost free hose bib that shuts off back in the wall. you should be able to find these at your local hardware store. remeber to take your hose off when it gets cold, if it drips it will freeze. i hope this helps.
