answer:Faucets aren’t typically glued down to counter surfaces, because you’ll likely want to change facets before you’ll want to change counter tops. Usually, a roll of “plumber’s putty” is pressed between the faucet base and the counter top to form a seal that prevents water from leaking under, then nuts secure the faucet from underneath the counter top. The plumber’s putty is non-adhesive and removable. You could easily get some putty at any hardware store (it’s cheap), and re-seat the faucet, making sure that the nuts are securely tightened. The nuts should be doing the lion’s share of the work of holding the faucet in place, with a little bit of help from the putty. You could go with one of the epoxy putties that are on the market, but the faucet would be forever wed to the counter.
